Answer:
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
If Voq doubles, abN gets multiplied by 16 .
If Voq=3, abN=81 .
Answer:
2.5 x 10⁻⁹ m
Explanation:
E = Energy of photon = 500 eV = 500 x 1.6 x 10⁻¹⁹ J
c = speed of photon = 3 x 10⁸ m/s
λ = wavelength of photon = ?
Energy of photon is given as
inserting the values
λ = 2.5 x 10⁻⁹ m
<span>So we want to know what does occur when light is refracted from a rough and unpolished surface. The correct answer is A. the original pattern of the light is distorted because rough and unpolished surfaces dissipate light in all directions so we cant get a clear image.</span>
