How long will it take to complete an orbit and where will it spend most of its time

Answer:

The correct option is;

The voltages become negative instead of positive and keep the same magnitudes

Explanation:

Here we have that there is a change in direction from positive to negative with the direction pointing to opposite of the initial direction whereby the field strength does not change due to the reversal of the. Therefore the voltage becomes negative instead of negative while keeping the the magnitude.

That is there is a electric field reversal or a change electric field direction.

Answer:

460 ohms

Explanation:

Resistance=Voltage/Current

=115/0.25=460

The resistance of the lamp can be calculated using Ohm's law, which states that resistance is equal to voltage divided by current. In this case, the resistance of the lamp is 460 ohms.

To find the resistance of a lamp, we can use Ohm's law, which states that resistance is equal to voltage divided by current.

R = V/I

From the given information, the voltage is 115 volts and the current is 0.25 amperes. Plugging these values into the equation, we get:

R = 115 V / 0.25 A = 460 ohms

Therefore, the lamp's resistance is 460 ohms.

Answer:

The study of Maxwell's equations and Ampere's law are used for analysis

Explanation:

Though There's a magnetic field associated with a changing electric field in TEM propagation of an EM wave through space (which is how it propogates, the changing E field begets the M field, the changeing M field begets the E field, leapfrogging each other).

But between capacitor plates, according to Maxwell and Ampere law, the displacement current in Ampere law was exactly to solve cases like that of a capacitor. A magnetic field cannot have discontinuities, unlike the electric field because there are electric charges, but there are no magnetic monopoles, at least as far as we know in the Universe in its current state. We can therefore conclude that there cannot be a magnetic field outside the capacitor and nothing inside

Answer:

Constructive interference occurs

Explanation

This is because at the point they both occupy the same region of space at the same time, there is a superposition of the waves causing them to add up. Since their amplitudes are equal and positive, they are in phase. and thus there is increase the resultant amplitude..This increase in amplitude is due to constructive interference.

Two wave pulses with equal positive amplitudes moving in opposite directions on a string will result in constructive interference where their displacements add up leading to an increased amplitude at the point of overlap. This is a momentary or transient event.

When two wave pulses with equal positive amplitudes meet each other on a string, moving in opposite directions, what we experience is constructive interference. This happens because the displacement of the two waves at every point adds up. Essentially, they combine to produce a wave of increased amplitude. In this case, the resultant wave would have an amplitude that's twice that of the individual wave pulses. Please note: this phenomenon happens only at the instant when both waves overlap and not any time before or after that. In other words, it's a transient or temporary phenomenon, not a permanent one, causing a momentary increase in the height of the wave at the point of intersection.

Time period of the pendulum T = 2 sec

We have to find acceleration due to gravity g

We know that time period of pendulum is given by

[tex]T=2\pi \sqrt{\frac{l}{g}}[/tex]

[tex]2=2\times 3.14 \sqrt{\frac{2}{g}}[/tex]

So option (E) will be correct answer.

Final answer:

Using the formula for the period of a simple pendulum and given values for length and period, the acceleration due to gravity on the planet is calculated to be approximately 9.87 m/s², which is closest to 10 m/s².

Explanation:

To determine the value of acceleration due to gravity (g) at the surface of a planet using a simple pendulum, we use the formula for the period (T) of a simple pendulum: T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

Rearranging the formula to solve for g gives us: g = (4π²L) / T². Given that the length (L) is 2 m and the period (T) is 2 s, we plug these values into the formula: g = (4π² × 2 m) / (2 s)².

Calculating this gives us: g = (4π² × 2 m) / 4, simplifying further gives g = π² × 2 m. Now substituting π = 3.14159, we find g = (3.14159)² × 2 m ≈ 9.87 m/s², which is closest to choice D: 10 m/s².

Answer:

It was made possible by the new methods of making steel

Explanation:

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron prior to the development of the open hearth furnace. The key principle used was the removal of impurities from the iron by process of oxidation with air being blown through the molten iron. The oxidation also enhances the temperature of the iron mass and keeps it molten. So with the presence of this, building of skyscraper was made possible.

Skyscrapers in the 1800s were made possible by the invention of steel girders and elevators, along with the high prices of real estate in city centers.

The construction of skyscrapers in the 1800s was made possible by several key advancements. One important development was the invention of steel girders that could support the weight of tall buildings. These girders allowed for the construction of buildings beyond the previous limit of 10 to 12 stories.

Another crucial factor was the invention of elevators, both passenger and freight elevators. The introduction of elevators made it feasible for people and goods to reach higher floors easily, making taller buildings more practical.

Additionally, the price of real estate in city centers played a significant role. As the cost of land increased, developers turned to building upwards to maximize space and value. These advancements in construction technology and the need for efficient use of space contributed to the rise of skyscrapers in the 1800s.

Answer:

a) 1.1mm

b) 2.513kg/ms^2

Explanation:

You can use the formula for the calculation of the wavelength of a wave

f=1.40MHz=1.40*10^{6}Hz

1 )

[tex]\lambda=\frac{v}{f}=\frac{1540m/s}{1.40*10^{6}Hz}=1.1*10^{-3}m=1.1mm[/tex]

2)

The Young modulus can be computed by using the expression:

[tex]v=\sqrt{\frac{Y}{\rho}}\\\\Y=v^2\rho[/tex]

where Y is the Young modulus and p is the density of the material. Here, you have considered that the prostate gland can be taken as a vibrating membrane or string.

By replacing you obtain:

[tex]Y=(1540m/s)^2(1060kg/m^3)=2.513*10^9kg/ms^2[/tex]

hence, the Young modulus of the prostate glande is 2.513kg/ms^2

Answer:

1) 1.1 x [tex]10^{-3}[/tex] m

2)2.51 x[tex]10^{9}[/tex]Pa

Explanation:

Given:

Speed of sound in prostate 'V'= 1540m/s

frequency 'f'  = 1.40 MHz = 1.40 x [tex]10^{6}[/tex]Hz

density of prostate'ρ' = 1060 kg/m3

1) As we know that the relationship of the speed of sound, its frequency, and wavelength is the same as for all waves

V= fλ

λ= V/f => 1540/1.40 x [tex]10^{6}[/tex]

λ= 1.1 x [tex]10^{-3}[/tex] m

Thus, the wavelength of the sonogram ultrasound is 1.1 x [tex]10^{-3}[/tex] m

2)The speed of sound in a solid the depends on the Young's modulus of the medium and the density

V=√Y/ρ.

V² = Y/ρ

Y= V² x ρ=> 1540² x 1060

Y= 2.51 x[tex]10^{9}[/tex]Pa

Thus, Young's modulus for the prostate gland is 2.51 x[tex]10^{9}[/tex]Pa

A stationary charge does not experience a force in a magnetic field. A moving charge experiences a force perpendicular to both its velocity and the magnetic field. A ferromagnetic object is attracted to a magnet regardless of its movement.

The magnetic force between a bar magnet and different charged materials can be understood in respect to the properties of the magnetic field, and these forces can range from attractive to repulsive depending on the orientation of the objects in the field and the type of materials involved. For a stationary charge, magnetic forces do not act on it because the magnetic force on a charged particle is always perpendicular to the direction of its motion. Hence, a stationary charged particle does not experience a force.

In the case of a moving charge, a magnetic field exerts force on it. This force is perpendicular to both the velocity of the charge and to the magnetic field, and is dependent on the magnitude of the charge, its speed, and the magnetic field. For example, if you place a moving charge in a magnetic field, the charge will experience a force that's oriented at right angles to both its direction of movement and the field itself. Ferromagnetic objects like iron or nickel will experience attraction to the magnet irrespective of their movement. It is the property of the ferromagnetic material to align its domains in the direction of the external magnetic field (from the bar magnet), thus the entire object acts like a small magnet and feels an attraction.

Answer:

The new angular velocity of the two stones = 160.064 rad/s

Explanation:

This is a case of conservation of angular momentum.

For initial case:

Mass = 50 kg

Radius = 0.75 m

Angular velocity N = 30 rev/s

We must convert to rad/s w

w = 2¶N = 2 x 3.142 x 30 = 188.52 rad/s

Moment of inertia I = m x r^2

I = 50 x 0.75^2 = 28.125 kgm2

Angular momentum = I x w

= 28.125 x 188.52 = 5302.125 kgm2-rad/s

For second case smaller stone has

m = 20 kg

Radius = 0.5 m

I = m x r^2 = 20 x 0.5^2 = 5 kgm2

Therefore,

Total moment of inertia of new system is

I = 28.125 + 5 = 33.125 kgm2

Final angular momentum = I x Wf

Where Wf = final angular speed of the system.

= 33.125 x Wf = 33.125Wf

Equating the two angular moment, we have,

5302.125 = 33.125Wf

Wf = 5302.125/33.125 = 160.064 rad/s

Pressure exerted by statue = [tex]15 kN/m^{2}[/tex]

Explanation:

Weight of the statue (F)= 3600 N

Area of the base of statue(A) = Length of the base x Width of the base

                                              =0.6 m x 0.4 m =0.24 m

Pressure is defined as  force per unit area.

[tex]Hence,\ pressure\ by\ statue= \frac{Force(F)}{Area(A)}=\frac{3600}{0.24} = 15000\ N/m^{2}[/tex]

Pressure exerted by statue = 15000 [tex]N/m^{2} = 15 kN/m^{2}[/tex]

The pressure exerted by the deer statue on the ground is approximately 15000 Pa.

Pressure is a measure of the force exerted per unit area. In physics, it is defined as the force acting perpendicular to the surface of an object divided by the area over which the force is applied.

To calculate pressure (P), we use the formula [tex]\(P = \frac{force}{area}\).[/tex] The force exerted by the statue is its weight, which is the gravitational force acting on it, given by [tex]\(F = mg\)[/tex], where (m) is the mass and (g) is the acceleration due to gravity (approximately 9.8 m/s²).

Given the weight of the statue [tex]\(3600 \, N\),[/tex] we find the mass using [tex]\(F = mg\)[/tex], rearranging to [tex]\(m = \frac{F}{g}\)[/tex], which gives [tex]\(m \approx \frac{3600 \, N}{9.8 \, m/s^2} \approx 367.35 \, kg\)[/tex].

Now, we find the area (\(A\)) of the base of the statue:[tex]\(A = \text{length} \times \text{width} = 0.60 \, m \times 0.40 \, m = 0.24 \, m^2\).[/tex]

Finally, we use the pressure formula [tex](P = \frac{F}{A}\): \(P \approx \frac{3600 \, N}{0.24 \, m^2} \approx 15000 \, Pa\).[/tex]

[tex]F = k \dfrac{q_{A}(q_{A}/3)}{d'^{2}}~~~~~~~~~~~~~~~~~~~~~~~~~~~(2)[/tex]

Equating equation (1) and equation (2), we have

[tex]~~~~&& \dfrac{1}{d'^{2}} = \dfrac{1}{3d^{2}}\\&or,& d' = \dfrac{d}{\sqrt{3}}[/tex]

Let the radius of the moon be "R".

And

The value of acceleration due to gravity is [tex]g_m[/tex] .

Formula:

⇒ [tex]g_m=\frac{GM}{R^2}[/tex]   ...where M is the mass of the moon.

Now

Gravity of the moon at the its surface:

⇒ [tex]g_m=\frac{GM}{R^2}[/tex]    ...equation (i)

Gravity of the moon at a distance of  [tex]4R[/tex]:

⇒ [tex]g_m_1=\frac{GM}{(4R)^2}[/tex]

⇒ [tex]g_m_1=\frac{GM}{16R^2}[/tex]   ...equation (ii)

Dividing equation (i) with (ii) to find the relationship between the two.

⇒ [tex]\frac{g_m_1}{g_m} =\frac{GM}{16R^2}\times \frac{R^2}{GM}[/tex]

⇒ [tex]\frac{g_m_1}{g_m} =\frac{1}{16}[/tex]

⇒ [tex]g_m_1 =g_m(\frac{1}{16})[/tex]

⇒ [tex]g_m_1 =x(\frac{1}{16})[/tex]    ...as gm=x at the surface.

So,

The minimum temperature of hot reservoir is 586K or 313°C

Explanation:

The Carnot cycle is defined as ideal reversible process thermodynamic process which has four successive step. During the expansion and compression of  the substance it can done upto desired point and then reversed up.

Here the energy is used from the hot reservoir to do work and deposited into the cold reservoir. As is it reversible the efficiency of the carnot cycle is the theoretical maximum of the heat engine.

The efficiency of carnot cycle is

η = 1 - [tex]\frac{Tc}{Th}[/tex]    eq 1

Where Tc is the temperature of cold reservoir = 20° = 20°+273K = 293K

           Th is the temperature of hot reservoir.

            η  is the efficency 50% = 0.5

The minimum temperature of the reservoir is related to the maximum efficiency,

Substituting values in eqn 1

0.05 = 1-[tex]\frac{293}{Th}[/tex]

Th = [tex]\frac{293}{1 - 0.5}[/tex] =586 K

The minimum temperature of hot reservoir is 586K.

ie 586K-273 = 313°C

Final answer:

The minimum hot-reservoir temperature required for a heat engine to have 50% efficiency with a cold reservoir at 20°C is 313.15°C.

Explanation:

To determine the minimum hot-reservoir temperature for a heat engine with 50% efficiency where the cold reservoir is at 20°C, we can use the efficiency formula for a Carnot engine: efficiency (e) = 1 - (Tc/Th), where Tc is the cold reservoir temperature and Th is the hot reservoir temperature, both in kelvins. Rearranging the formula to solve for Th gives: Th = Tc / (1 - e).

First, convert the cold reservoir temperature from Celsius to Kelvin: Tc = 20°C + 273.15 = 293.15 K. Now, plug in the efficiency value: Th = 293.15 K / (1 - 0.50) = 293.15 K / 0.50 = 586.3 K. Convert this back to Celsius to get the minimum hot-reservoir temperature required: Th - 273.15 = 586.3 K - 273.15 = 313.15°C.

Therefore, the minimum hot-reservoir temperature required for the proposed heat engine to reach 50% efficiency is 313.15°C.

We pass the distance from Ro = 1.49 10¹¹ m to r = 0.736 10¹¹ m shortens, we write Newton's second law

             F = m a

where the force is the universal force of attraction

            F = G mM / r²

acceleration is central

            a = v² / r

           G m M / r² = m v² / r

            v = √ (G M / r)

When we change the distance, the universal attraction force increases, so that the system is free to reach a new equilibrium, the linear speed of the earth must rise to the calculated value.

We can compare this value with that of the normal orbit

           v₀ = √ (GM / R₀)

            v / v₀ =√ (Ro / r)

           v² r = v₀² R₀

 either of these two expressions gives the relations gives the change in velocity with the radius of the orbit

The table shows mass energy and constant velocity. Let's calculate a constant factor, multiply it by mass, get the energy and see if we can do it. It's very easy. You can do it just in case. Only kinetic energy divided by mass can be produced. That is, the first is 100 and 21.5 divided by 27. Now you have the next 4.5. This is one. Then it is 162 divided by 36. This is 4.5. January 3, 202

Divide 5 by 45 to get 4.5. And hopefully you can see the patterns that are appearing here. In the fourth one, 243 divided by 54 gives 4.5. The fifth 288 divided by 64. Since it is 4.5, you can guess what it will be like. And finally, in the sixth case, it's 3 to 8.5 divided by 73. This is also equivalent to 4. Well, this common factor 4.5 was found.

Kinetic energy is a form of energy that an object or particle has due to its movement. When work is done on an object by applying a net force that transfers energy, the object accelerates, thereby gaining kinetic energy. In physics, the kinetic energy of an object is the energy that the object has due to its motion.

This is defined as the work required to accelerate an object of a given mass from a stationary state to a specified velocity. After the body gains this energy during acceleration, the body retains this kinetic energy unless the velocity changes.

All moving objects use kinetic energy. Examples of kinetic energy are walkers, thrown baseball, bread crumbs falling from a table, and charged particles in an electric field.

Given that,

A space ship is separated into two part

Mass of first part

M1 = 1200kg

Mass of second part

M2 = 1800kg

Magnitude of impulse on each part is

I = 300Ns

We want to find the relative velocity at which the two parts separate

Now,

Impulse is give as

I = ft = mv - mu

Since the body is considered to be at rest before detonation

Then, I = mv

So for first part

I = M1•V1

V1 = I / M1

V1 = 300 / 1200

V1 = 0.25m/s

Also, for second part

V2 = —I / M2

V2 = —300 / 1800

V2 = —0.167 m/s

NOTE: the negative sign is due to the fact that the two bodies are moving away from each other.

The relative speed of the two masses because of detonation is

V = V1 — V2

V = 0.25 — (—0.167)

V = 0.25 + 0.167

V = 0.417 m/s

The relative speed of the two masses because of detonation is 0.417 m/s

Lets say two parts went left and right, one with 1200Kg, call it A ,went right and one with mass 1800Kg went left. Let's establish right as positive and left as negative for our speed convention.

Both have initial acceleration of 300N, assuming for one second, by newton's second law F=ma, 'A' will have acceleration of 1/4m/s^ which will induce velocity of 0.25m/s as well.

So A has velocity of [tex]\frac{1}{4} m/s[/tex] towards right direction.

and B has velocity of - [tex]\frac{1}{6} m/s[/tex] towards left direction.

and 'B' will have acceleration of [tex]\frac{1}{6} m/s^2[/tex] which will also produce velocity of [tex]\frac{1}{6} m/s[/tex].

[tex]V_{AB} = V_{A} -V_{B}[/tex] = [tex]$\frac{1}{4} --\frac{1}{6}= \frac{5}{12}m/s[/tex] (Read as Velocity A with respect to B) (1)

The gravitational force between a proton and an electron is 40 * 10⁻⁴⁸ N

Newton's law of gravitation is given by:

F = Gm₁m₂/r²

Where F is the force, m₁, m₂ are masses, r is the distance between the two masses and G is the gravitational constant = 6.67 * 10⁻¹¹ Nm²/kg²

Given that:

m₁ = 1.67 * 10⁻²⁷ kg, m₂ = 9.11 * 10⁻³¹ kg, r = 5 * 10⁻¹¹ m, hence:

F = 6.67 * 10⁻¹¹ Nm²/kg² * 1.67 * 10⁻²⁷ kg * 9.11 * 10⁻³¹ kg/ (5 * 10⁻¹¹ m)²

F = 40 * 10⁻⁴⁸ N
