A proton and an electron are held in place on the x axis. The proton is at x = -d, while the electron is at x = +d. They are released simultaneously, and the only force that affects their motions is the electrostatic force of attraction that applies to the other. Which particle reaches the origin first? Give your reasoning.

Answers

Answer 1

The protons and electrons are held in place on the x axis.
The proton is at x = -d and the electron is at x = +d. They are released at the same time and the only force that affects movement is the electrostatic force that is applied on both subatomic particles. According to Newton's third law, the force Fpe exerted on protons by the electron is opposite in magnitude and direction to the force Fep exerted on the electron by the proton. That is, Fpe = - Fep. According to Newton's second law, this equation can be written as
Mp * ap = -Me * ae
where Mp and Me are the masses, and ap and ae are the accelerations of the proton and the electron, respectively. Since the mass of the electron is much smaller than the mass of the proton, in order for the equation above to hold, the acceleration of the electron at that moment must be considerably larger than the acceleration of the proton at that moment. Since electrons have much greater acceleration than protons, they achieve a faster rate than protons and therefore first reach the origin.

Answer 2

Final answer:

The electron will reach the origin first due to its greater acceleration, which is a result of its much smaller mass compared to the proton, despite the forces on both particles being equal in magnitude.

Explanation:

The question is asking which particle, a proton at x = -d or an electron at x = +d that are released simultaneously under the influence of electrostatic force, will reach the origin first. According to Newton's second law, force equals mass times acceleration (F = ma). Because the proton and the electron have equal and opposite charges, the magnitude of the force acting on them due to their electrical interaction will be the same. However, the mass of the proton is much greater than that of the electron, resulting in much smaller acceleration for the proton. Consequently, the electron, given its smaller mass and therefore larger acceleration, will reach the origin first.

Extend your thinking: household appliances are usually connected in a parallel circuit. why do you think it might be a problem if too many appliances are turned on at once? (hint: current in a wire also produces heat.)

Answers

The equivalent resistance of several devices connected in parallel is given by
[tex] \frac{1}{R_{eq}} = \frac{1}{R_1}+ \frac{1}{R_2}+...+ \frac{1}{R_n} [/tex]
where [tex]R_i[/tex] are the resistances of the various devices. We can see that every time we add a new device in parallel, the term [tex] \frac{1}{R_{eq}} [/tex] increases, therefore the equivalent resistance of the circuit [tex]R_{eq}[/tex] decreases.

But Ohm's law:
[tex]I= \frac{V}{R_{eq}}[/tex]
tells us that if the equivalent resistance decreases, the total current in the circuit increases. The power dissipated through the circuit (and so, the heat produced) depends on the square of the current:
[tex]P=I^2 R[/tex]
therefore if there are too many devices connected in parallel, this can be a problem because there could be too much power dissipated (and too much heat) through the circuit.

There might be a problem of a lot of power being dissipated if too many

appliances are turned on at once.

We can infer from Ohm's law that as resistance decreases, the total current increases.

I= V/R

The power dissipated through the circuit is directly proportional to the square

of the current.

P= I²R

We can therefore state that the power dissipated via heat will be much when

too many appliances are turned on at once.

Therefore;
5273.5t = 1000*4186*(65-20) = 188370000
t = 188370000/5273.5 = 35720.11 seconds = 35720.11/(60*60) hours ≈ 9.92 hours.

An electron has kinetic energy 3.00 ev. find its wavelength.

3 eV corresponds to
[tex]K=3 eV = 3 \cdot 1.6 \cdot 10^{-19}J=4.8 \cdot 10^{-19} J[/tex]

The kinetic energy of an electron is related to its momentum by the formula
[tex]K= \frac{p^2}{2m} [/tex]
where p is the electron's momentum, while m is its mass. Re-arranging the formula, we find
[tex]p= \sqrt{2Km}= \sqrt{2 (4.8 \cdot 10^{-19}J)(9.1 \cdot 10^{-31} kg)}=9.35 \cdot 10^{-25} kg m/s [/tex]

And then we can use De Broglie relationship to find its wavelength:
[tex]\lambda= \frac{h}{p}= \frac{6.6 \cdot 10^{-34}Js}{9.35 \cdot 10^{-25} kg m/s}=7.06 \cdot 10^{-10} m [/tex]

If we plug these numbers into the first equation, we find the muon momentum:

A ground wire provides a conducting path to the earth which is separate and independent from the path of an electrical appliance. Also, a ground wire is an additional pathway for an electric current to safely return to the ground without imposing danger to anyone in the event that a short circuit might occur.

In the absence of air resistance and friction, what will happen to the velocity of an object going at 20 m/s E?

Answers

In the absence of any other forces, the object will continue to move at 20 m/s E.

In fact, Newton's second law states that the resultant of the forces acting on an object is equal to the product between the mass and the acceleration of the object:

therefore, if there are no forces acting on the object, the term on the left is zero, and the acceleration of the object is zero as well. This means that the object will continue its motion with constant speed, and in the same direction.

3. It should be non-obvious which is easily recognizable.
It is easy to understand. The three qualities are being possessed by novel VOLTa as the concept is very new and it will be very beneficial for the world or public.

Final answer:

In advising Volta on patenting a clean energy engine, it is essential to consider thermodynamic laws, which preclude the possibility of engines that produce more energy than used or have 100% efficiency, and acknowledge the efficiency limits set by the Carnot cycle.

Explanation:

When considering a patent for a novel clean energy engine, it is important to understand fundamental principles of thermodynamics, which would challenge the claim of an engine running by burning hydrogen that allegedly produces more energy than it uses. Such a system would violate the second law of thermodynamics, as it implies perpetual motion or over-unity efficiency, which is physically impossible because it would create energy from nothing. Likewise, claiming a 100% efficient motor also breaks this immutable law of physics, as all systems produce waste heat due to inefficiencies.

A typical gasoline car engine cannot achieve 100% efficiency due to these losses through heat, friction, and sound, among other factors. The theoretical efficiency ceiling for a gasoline engine is dictated by the Carnot cycle, which is typically less than 45% for a combustion engine. In terms of adopting clean energy technologies like geothermal power and vehicles running on electric or hydrogen fuel cells, it is important to approach these with a balanced view, recognizing both the environmental benefits and the practical limitations or challenges of these technologies.

The humber bridge in england has the world's longest single span, 1410 m . calculate the change in length of the steel deck of the span when the temperature increases from -3.0 ∘c to 18.5 ∘c.

Answers

Applicable linear expansion equation:
ΔL = αΔTL
In which
ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length

Final answer:

The steel deck of the Humber Bridge would expand by 0.362 meters (362 millimeters)

Explanation:

To calculate the change in length of the steel deck of the Humber Bridge when the temperature increases you need to use the linear thermal expansion formula: [tex]\(\Delta L = \alpha L_0 \Delta T\),[/tex] where [tex]\(\Delta L\)[/tex]is the change in length, \(\alpha\) is the coefficient of thermal expansion for steel [tex](\12 x 10^-6 /\u2103\), \(L_0\)[/tex] is the original length of the steel structure, and \(\Delta T\) is the change in temperature.

First, find the change in temperature: [tex]\(18.5 \u2103 - (-3.0 \u2103) = 21.5 \u2103\).[/tex]

Then, use the given length of the Humber Bridge span (1410 meters) and plug these values into the equation:

[tex]\(\Delta L = (12 x 10^{-6}/\u2103)(1410 m)(21.5 \u2103)\)[/tex]

By doing the calculation:

[tex]\(\Delta L = 0.362 m\)[/tex]

The steel deck of the Humber Bridge would expand by 0.362 meters (or 362 millimeters).

A car moves along a curved road of diameter 2 km. If the maximum velocity for safe driving on this path is 30 m/s, at what angle has the road been banked? (Ignore friction.)

Answers

The maximum velocity in a banked road, ignoring friction, is given by;

v = Sqrt (Rg tan ∅), where R = Radius of the curved road = 2*1000/2 = 1000 m, g = gravitational acceleration = 9.81 m/s^2, ∅ = Angle of bank.

Substituting;
30 m/s = Sqrt (1000*9.81*tan∅)
30^2 = 1000*9.81*tan∅
tan ∅ = (30^2)/(1000*9.81) = 0.0917
∅ = tan^-1(0.0917) = 5.24°

Therefore, the road has been banked at 5.24°.

Final answer:

To calculate the bank angle for a curve of diameter 2 km (radius 1 km) to be driven at 30 m/s without relying on friction, the physics concepts of centripetal force and gravitational force component due to the bank angle are applied.

Explanation:

In this scenario, the safety of driving on a curved road relies on the balance between the inward centripetal force required for the car to maintain its curved path and the normal force exerted by the road on the car. The normal force acts perpendicular to the road surface and has both horizontal and vertical components.

To find the angle at which the road is banked, we first calculate the centripetal force required for the car to negotiate the curve safely. This force is given by the formula [tex]\( F_c = \frac{mv^2}{r} \)[/tex], where [tex]\( m \)[/tex] is the mass of the car, [tex]\( v \)[/tex]is the velocity of the car, and [tex]\( r \)[/tex] is the radius of the curve. Given that the diameter of the road is 2 km, the radius[tex]\( r \)[/tex]is half of this distance.

Once we determine the centripetal force, we recognize that it must be balanced by the horizontal component of the normal force. The vertical component of the normal force counteracts gravity. Therefore, the angle at which the road is banked can be found by taking the inverse tangent of the ratio of the centripetal force to the gravitational force.

By calculating this angle, we can determine the angle at which the road must be banked to safely accommodate the car's velocity while moving along the curved path. In this case, the calculated angle is approximately [tex]\( 5.22^\circ \).[/tex]

The force of the bow on the arrow is equal and opposite to the force of the arrow on the bow, complying with Newton's Third Law. The energy to shoot an arrow comes from converting kinetic energy to potential energy, and then back to kinetic energy upon release. Projectile range is affected by the angle of release and external factors like wind.

Explanation:

When a bow and arrow is fired, the size of the force of the bow on the arrow is equal to the size of the force of the arrow on the bow. This is due to Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In terms of archery, when the archer releases the string, the potential energy stored in the bow is transferred to the arrow, propelling it forward. At the same time, the bow experiences an equal and opposite force.

Energy and Projectile Motion

The energy it takes to shoot an arrow involves converting kinetic energy from pulling the string into potential energy stored in the string. Upon release, this potential energy turns back into kinetic energy, which determines the speed and range of the arrow. For a fixed initial speed, the range of a projectile like an arrow is determined by the angle of release. The smaller angle is often preferable due to minimal air resistance and other factors like wind, while a larger angle may be useful to shoot over obstacles or reach longer distances, as with a football punter using a higher trajectory to maximize hang time.
