An object that has momentum can NOT also be _____.
A. In free fall motion
B. At rest
C. Moving along a curved path
D. Slowing down
Answers
Explanation:
The equation to find momentum is velocity*mass. Without velocity, there would be no momentum. Therefore the object CAN NOT be at rest.
Answer:
B
Explanation:
if the object has momentum it can be any other answer except at rest. if it's at rest, it does not have momentum

Stars emit different wavelengths of visible light due to their different
temperatures. How does this phenomenon support the particle model of
light?
A. It is the result of interference.
B. It is the result of diffraction.
C. It is the result of the photoelectric effect.
D. It is the result of blackbody radiation.
Answers
Answer:
D
Explanation:
Just did it
The particles model of light supports the the photoelectric effect, where, light in the form of tiny packets called photons when hit on a metal surface it ejects electrons.
What is photelectric effect?Photoelectric effect is discovered by Albert Einstein. When a light ray hit on a solid surface, the photon or light particle emits from the surface which is having the equal energy as that of the incident photon.
According to wave -particle duality of matter, light can exhibit both particle and wave nature. If light behaves as a particle of specific energy, the light particle is called photon.
Stars emit light in different wavelengths of visible light at different temperatures. The wavelength is equal to the speed of light divided by the frequency. The excitation of electron depends on the temperature also. This effect indicating the particle nature of light.

if your weight is 600 Newton on the earth how far should you go from the centre of the earth so that it will be 300 Newton
Answers
Given :
Our weight is 600 Newton on the earth.
To Find :
How far should you go from the center of the earth so that it will be 300 Newton.
Solution :
Acceleration due to gravity at depth d is given by :
[tex]g' = g( 1 - \dfrac{d}{R_e})[/tex]
At earth surface, mg = 600 N ...1)
At depth d, mg' = 300 N ...2)
Dividing 1) and 2), we get :
[tex]\dfrac{g}{g'} = \dfrac{600}{300}\\\\\dfrac{g}{g'} = 2\\\\g = 2g'\\\\g = 2\times g\times ( 1 - \dfrac{d}{R_e} )\\\\1 - \dfrac{d}{R_e} = \dfrac{1}{2} \\\\d = \dfrac{R_e}{2}[/tex]
Therefore, we should go in the depth of distance half the radius of earth.

why will light from the sun change the color of the cloth when the light from the desk lamp does not
Answers
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

An athlete completes one round of circular track of diameter 200 meter in 40 sec. What will be the distance covered and the displacement at the end of 2 meter 20 seconds ?
Answers
Answer:
400m
Explanation:
If An athlete completes one round of circular track of diameter 200 meter in 40 sec, we can write;
200m = 40sec
To determine the distance after 2min 20secs, we can write;
x = 2,min 20sec
x = 80sec
Divide both expression
200/x = 40/80
200/x = 1/2
x = 2×200
x = 400m
Hence the distance covered after 2min 20secs is 400m
