A spring tide can occur for position A but not for position B.

Answer 2

A spring tide can occur for position A but not for position B. This statement is true regarding the type of tides that can occur. Hence option D is correct.

What is spring tide and neap tides ?

A spring tide, sometimes referred to as a "King Tide," is the term used to describe the tide's springing forth' during new and full moons.

Seven days following a spring tide, there is a period of moderate tides known as a neap tide, which occurs when the sun and moon are at right angles to one another.

The ocean is "tugged" back and forth by the gravitational attraction of the moon and the sun when these bodies interact with the Earth in their monthly and yearly orbits, causing long-period waves to roll around the globe.

Average tidal ranges are a little bit larger during full or new moons, which happen when the Earth, sun, and moon are approximately aligned. That happens twice a month. When the moon lies exactly between the Earth and the sun, it seems fresh (dark). When the Earth is situated between the moon and the sun, the moon seems to be full. In both instances, the Earth's seas bulge a little bit more than usual due to the gravitational attraction of the sun being "added" to that of the moon. This indicates that the high tides are a bit higher and the low tides a little lower than usual.

Hence option D is correct.

Determine the pressure exerted by 2.50 mol of gas in a 2.92 l container at 32 oc.

Answers

I guess you meant "at [tex]32^{\circ}C[/tex]"

Solution:
we can solve the problem by using the ideal gas law, which states:
[tex]pV=nRT[/tex]
where
p is the gas pressure
V its volume
n the number of moles
R the gas constant
T the absolute temperature

Before using this equation, we have to convert the temperature in Kelvin:
[tex]T=32^{\circ}C+273 = 305 K[/tex]
and the volume in [tex]m^3[/tex]:
[tex]V=2.92 L= 2.92 dm^3 = 2.92 \cdot 10^{-3} m^3[/tex]

So now we can re-arrange the ideal gas equation to find the pressure exerted by the gas, p:
[tex]p= \frac{nRT}{V}= \frac{(2.50 mol)(8.31 J/mol K)(305 K)}{2.92 \cdot 10^{-3} m^3}= 2.17 \cdot 10^7 Pa[/tex]

The correct order is the following:

1) An atom fission
2) Neutrons are produced
3) Neutrons find other atoms

Answers

There is a missing data in the text of the problem (found on internet):
"with force constant k=450N/m"

a) the maximum speed of the glider

The total mechanical energy of the mass-spring system is constant, and it is given by the sum of the potential and kinetic energy:
[tex]E=U+K= \frac{1}{2}kx^2 + \frac{1}{2} mv^2[/tex]
where
k is the spring constant
x is the displacement of the glider with respect to the spring equilibrium position
m is the glider mass
v is the speed of the glider at position x

When the glider crosses the equilibrium position, x=0 and the potential energy is zero, so the mechanical energy is just kinetic energy and the speed of the glider is maximum:
[tex]E=K_{max} = \frac{1}{2}mv_{max}^2 [/tex]
Vice-versa, when the glider is at maximum displacement (x=A, where A is the amplitude of the motion), its speed is zero (v=0), therefore the kinetic energy is zero and the mechanical energy is just potential energy:
[tex]E=U_{max}= \frac{1}{2}k A^2 [/tex]

Since the mechanical energy must be conserved, we can write
[tex] \frac{1}{2}mv_{max}^2 = \frac{1}{2}kA^2 [/tex]
from which we find the maximum speed
[tex]v_{max}= \sqrt{ \frac{kA^2}{m} }= \sqrt{ \frac{(450 N/m)(0.040 m)^2}{0.500 kg} }= 1.2 m/s[/tex]

b) the speed of the glider when it is at x= -0.015m

We can still use the conservation of energy to solve this part.
The total mechanical energy is:
[tex]E=K_{max}= \frac{1}{2}mv_{max}^2= 0.36 J[/tex]

At x=-0.015 m, there are both potential and kinetic energy. The potential energy is
[tex]U= \frac{1}{2}kx^2 = \frac{1}{2}(450 N/m)(-0.015 m)^2=0.05 J [/tex]
And since
[tex]E=U+K[/tex]
we find the kinetic energy when the glider is at this position:
[tex]K=E-U=0.36 J - 0.05 J = 0.31 J[/tex]
And then we can find the corresponding velocity:
[tex]K= \frac{1}{2}mv^2 [/tex]
[tex]v= \sqrt{ \frac{2K}{m} }= \sqrt{ \frac{2 \cdot 0.31 J}{0.500 kg} }=1.11 m/s [/tex]

c) the magnitude of the maximum acceleration of the glider;

For a simple harmonic motion, the magnitude of the maximum acceleration is given by
[tex]a_{max} = \omega^2 A[/tex]
where [tex]\omega= \sqrt{ \frac{k}{m} } [/tex] is the angular frequency, and A is the amplitude.
The angular frequency is:
[tex]\omega = \sqrt{ \frac{450 N/m}{0.500 kg} }=30 rad/s [/tex]
and so the maximum acceleration is
[tex]a_{max} = \omega^2 A = (30 rad/s)^2 (0.040 m) =36 m/s^2[/tex]

d) the acceleration of the glider at x= -0.015m

For a simple harmonic motion, the acceleration is given by
[tex]a(t)=\omega^2 x(t)[/tex]
where x(t) is the position of the mass-spring system. If we substitute x(t)=-0.015 m, we find
[tex]a=(30 rad/s)^2 (-0.015 m)=-13.5 m/s^2[/tex]

e) the total mechanical energy of the glider at any point in its motion.

we have already calculated it at point b), and it is given by
[tex]E=K_{max}= \frac{1}{2}mv_{max}^2= 0.36 J[/tex]

Final answer:

To compute the maximum speed, use the equation vmax = Aω. At x = 0, the speed is 0. The maximum acceleration is given by amax = Aω².

Explanation:

To compute the maximum speed of the glider, we can use the equation vmax = Aω, where A is the amplitude (0.040 m) and ω is the angular frequency. The angular frequency is given by ω = √(k/m), where k is the force constant (N/m) and m is the mass (kg). In this case, k = 80 N/m and m = 0.500 kg.

For part (b), the speed of the glider when it is at x = 0 (the equilibrium position) is 0. This is because the velocity is at a maximum when the glider passes through the equilibrium position, and at that point, it changes direction.

The maximum acceleration of the glider can be found using the equation amax = Aω². The magnitude of the maximum acceleration occurs at the position x = -A, so we can substitute -A for x in the equation. Finally, the acceleration of the glider at x = -A can be found by substituting this value into the equation a = -Aω².

If a 100N weight sits in an express elevator what will be the weight when the elevator is traveling at a constant speed

Answers

This is a "trick" question.

If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.

So the 100N weight's weight doesn't change in an elevator traveling at constant speed.

Final answer:

The weight of the 100N weight will remain the same when the elevator is travelling at a constant speed.

Explanation:

When the elevator is travelling at a constant speed, the weight of the 100N weight will remain the same. The weight of an object is the force exerted on it due to gravity, and this force does not change regardless of the elevator's speed or direction. So, the weight of the object will still be 100N.

Jody has a mass of 50 kilograms what is his weight on earth

Answers

Final answer:

Jody's weight on Earth is calculated by multiplying his mass (50 kg) by Earth's standard gravity (9.81 m/s^2), which equals 490.5 newtons.

Explanation:

When calculating the weight of an object on Earth, we need to account for the force of gravity acting upon the object's mass. The standard acceleration due to gravity on Earth is approximately 9.81 meters per second squared (m/s2). To find Jody's weight, we multiply his mass by the acceleration due to gravity:

Weight = Mass times Earth's gravity

Weight = 50 kg times 9.81 m/s2

Weight = 490.5 N (newtons)

Therefore, on Earth, Jody weighs 490.5 newtons.

2. Something causes an object to vibrate.

3. Vibrating air particles bump into other air particles.

4. Air particles around the object begin to vibrate.

5. Energy transfers outward from air particle to air particle.

Answers

Answer: The order is 2,1,5,4,3

Explanation: Hope This helps.

The order in which events occur in the generation and transmission of a sound wave begins with an object vibrating, which transfers energy to air particles, leading to the vibration of surrounding air and the eventual transfer of energy from particle to particle, forming a sound wave.

Sound is produced and travels through a medium via a series of events that can be listed in sequential order:

Something causes an object to vibrate.

The object's energy transfers to the surrounding air particles.

Air particles around the object begin to vibrate.

Vibrating air particles bump into other air particles.

Energy transfers outward from air particle to air particle.

For example, when a tuning fork is struck, its tines vibrate and cause air molecules nearby to oscillate. These vibrations propagate outward as successive air molecules collide, similar to ripples in water when a stone is thrown. This movement of air molecules forms a sound wave, which can be detected by the ear as changes in air pressure and interpreted as sound.

Calculate the diameter of the fifteenth orbit of the hydrogen atom if the diameter of the innermost orbit is 1.06 A. (Hint: Keep three significant figures in your answer.)

Answers

In an atom of hydrogen the orbit radius is given by the formula:
r = n² · α₀

where:
n = number of orbit = 15
α₀ = Bohr radius (innermost radius) = 0.529 Â

Since d = 2 · r, we can write:
d = n² · d₀
= 15² · 1.06
= 238.5 Â

Hence, the diameter of the fifteenth orbit of the hydrogen atom is 238.5 Â.

Certain underwater vehicles are capable of exploring some of the deepest regions of the ocean. consider the density of seawater to be 1025 kg/m3. if such a vehicle were submerged to a depth of 8513 m below the surface, what force would be exerted on the vehicle's observation window (radius = 9.3 cm)?

Answers

The pressure exerted by the water at a depth of h=8513 m below the surface is given by Stevin's law:
[tex]p=p_a + \rho g h[/tex]
where
[tex]p_a =1.013\cdot 10^5 Pa[/tex] is the atmospheric pressure
[tex]\rho=1025 kg/m^3[/tex] is the water density
[tex]g=9.81 m/s^2[/tex] is the gravitational acceleration
[tex]h=8513 m[/tex] is the depth

If we plug the numbers into the formula, we find the pressure exerted on the window of the vehicle:
[tex]p=1.013 \cdot 10^5 Pa + (1025 kg/m^3)(9.81 m/s^2)(8513 m)=8.57 \cdot 10^7 Pa[/tex]

The area of the window is
[tex]A=\pi r^2 = \pi (0.093 m)^2 = 0.027 m^2[/tex]

And so the force exerted on the window is
[tex]F=pA=(8.57 \cdot 10^7 Pa)(0.027 m^2)=2.31 \cdot 10^6 N[/tex]

Find the total translational kinetic energy of 1.5 l of oxygen gas held at a temperature of 0°c and a pressure of 0.8 atm.

Answers

The ideal gas law states that:
[tex]pV=nRT[/tex]
where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature

However, this equation can be also rewritten as
[tex]PV= \frac{2}{3}NK [/tex] (1)
where
N is the number of molecules in the gas, and K is the average kinetic energy of the molecules. Therefore, NK represents the total kinetic translational energy of the gas.

For the gas in our problem,
[tex]p=0.8 atm = 8.08 \cdot 10^4 Pa[/tex]
[tex]V=1.5 L =1.5 \cdot 10^{-3} m^3[/tex]
So, the total translational kinetic energy of the gas is (using eq.(1) )
[tex]NK= \frac{3}{2}pV= \frac{3}{2}(8.08 \cdot 10^4 Pa)(1.5 \cdot 10^{-3} m^3)=181.8 J [/tex]

Final answer:

To calculate the total translational kinetic energy of 1.5 liters of oxygen gas at 0°C and 0.8 atm, use the ideal gas law to find the number of moles and then apply the translational kinetic energy equation (KEtrans = (3/2)nRT).

Explanation:

To find the total translational kinetic energy (KEtrans) of 1.5 liters of oxygen gas at 0°C (273 K) and 0.8 atm, we can use the ideal gas law and the equipartition theorem. The ideal gas law PV = nRT can give us the number of moles of oxygen gas when rearranged to n = PV/RT. Here, P is the pressure, V is the volume, R is the ideal gas constant, and T is the temperature.

Once the moles (n) are calculated, the translational kinetic energy per mole of a gas can be found using the equation KEtrans = (3/2)nRT, where n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. By substituting the values into the equation, we can find the total translational kinetic energy of the gas sample.

Even without knowing the precise value of the pure water resistivity, we can estimate the ratio between the pure water resistivity and the silver resistivity by comparing the two orders of magnitude:

What is Resistivity?

The property of the material that determines the actual resistance offered by the material to the flow of current through a cross-section area, is known as the resistivity of the material.

Pure water is a bad conductor of electricity which means it offers high resistance to the flow of electric current. So, the standard value of the resistivity of pure water is around [tex]10^{3} \;\rm \Omega.m[/tex].

On the other hand, silver is one of the materials which allows higher conduction of electricity through it, hence it has a lower level of resistivity of the order [tex]1.60 \times 10^{-8} \;\rm \Omega.m[/tex]

So, the ratio of resistivity of water to the silver is,

What is the maximum kinetic energy of the photoelectrons when light of wavelength 285 nm falls on the same surface?

Answers

In the photoelectric effect, the energy of the incoming photon is used partially to extract the photoelectron from the metal (work function) and the rest is converted into kinetic energy of the photoelectrons:
[tex]hf=\phi + K_{max}[/tex] (1)
where
h is the Planck constant
f is the photon frequency
[tex]\phi[/tex] is the work function
[tex]K_{max}[/tex] is the maximum kinetic energy of the photoelectrons

In the first part of the problem, we have light with wavelength [tex]\lambda=400 nm=400 \cdot 10^{-9} m[/tex], so the photons have frequency
[tex]f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{400 \cdot 10^{-9} m}=7.5 \cdot 10^{14}Hz [/tex]
where c is the speed of light; and therefore the energy of the photons is
[tex]E=hf=(6.6 \cdot 10^{-34}Js)(7.5 \cdot 10^{14} Hz)=5.0 \cdot 10^{-19} J[/tex]
Converted into electronvolts ([tex]1 eV= 1.6 \cdot 10^{-19} J[/tex]):
[tex]E=5.0 \cdot 10^{-19} J =3.12 eV[/tex]

The maximum kinetic energy of the photoelectrons in this case is
[tex]K_{max}=1.10 eV[/tex], so we can find the work function of the metal by re-arranging eq. (1):
[tex]\phi = hf-K_{max} = 3.12 eV-1.10 eV=2.02 eV[/tex]

In the second part of the problem, we have light with wavelength [tex]\lambda=285 nm=285 \cdot 10^{-9}m[/tex], which corresponds to a frequency of
[tex]f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{285 \cdot 10^{-9}m}=1.05 \cdot 10^{15} Hz [/tex]
And so the photons have energy
[tex]E=hf=(6.6 \cdot 10^{-34} Js)(1.05 \cdot 10^{15}Hz)=6.93 \cdot 10^{-19} J[/tex]
which corresponds to
[tex]E=6.93 \cdot 10^{-19}J = 4.33 eV[/tex]

And if we use again eq.(1), we can now find the new maximum kinetic energy of the photoelectrons:
[tex]K_{max}=hf-\phi=4.33 eV-2.02 eV=2.31 eV[/tex]

Zero degrees Celsius is simply the freezing point of water. At this point, all molecular motion and energy cease, and no heat remains in matter.

It is a fundamental concept in thermodynamics and the basis for the Kelvin temperature scale. Achieving absolute zero is impossible in practice, but scientists have come close, allowing the study of quantum phenomena and materials at extremely low temperatures, leading to breakthroughs in physics and technology.
