Answer:
The answer is h/4
Explanation:
When Peter collides with Fred, the collision is inelastic & they both proceed with a velocity of V/2.
let m represent the masses for Peter & Fred
v represent the initial velocity of Peter
V represent final velocity of both of them
mv + 3m × 0 = (m+m)V
V = v/2
Using the expression; H = v² / 2g .............Eqn 1
Upon substitution of V/2 into Eqn 1 above,
H = (V/2)² / 2g
H = (V²/4) ÷ 2g
Therefore height will be h/4
Answer:

Explanation:
a prism is a cut piece of clear glass or plastic in the form of a triangular prism that separates white light into a spectrum through ----------?
The correct answer is forces are equal but opposite in direction between car and bus.
What do we mean by Collision?
When two objects collide, forces of equal magnitude and opposite direction are applied to each object. Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum).
The force applied to an object to cause an impact—a change in momentum—on it is referred to as the impact force, or momentum. Technically speaking, the Car and the bus would have exerted and felt the same amount of impact force in the event of a collision. Because every action has a corresponding and opposing response, according to Newton's third law.

(a) 
The energy of a photon is given by:
where
is the Planck constant
is the speed of light
is the wavelength
For the microwave photon,
So the energy is
And converting into electronvolts,
(b) 
For the energy of the photon, we can use the same formula:
For the visible light photon,
So the energy is
And converting into electronvolts,
(c) 
For the energy of the photon, we can use the same formula:
For the x-ray photon,
So the energy is
And converting into electronvolts,
