Explanation :
The energy of a wave is given by:
Where,
h is the planck's constant
c is the speed of light
is the wavlength
One more factor on which the energy of the wave depends is the amplitude of the wave.
The maximum displacement of the particle is called the amplitude of the wave.
The particles transports energy from one location to another.
Hence, the correct option is (a) " High energy waves have high amplitudes".
Increasing speed, decreasing speed, or a change in direction
Answer:
10 mm
Explanation:
We'll begin by calculating the spring constant of the spring. This can be obtained as follow:
Extention (e) = 5 mm
Force (F) = 125 N
Spring constant (K) =?
F = Ke
125 = K × 5
Divide both side by 5
K = 125 / 5
K = 25 N/mm
Finally, we shall determine how much the spring will stretch when a 250 N force is applied. This can be obtained as follow:
Force (F) = 250 N
Spring constant (K) = 25 N/mm
Extention (e) =?
F = Ke
250 = 25 × e
Divide both side by 25
e = 250 / 25
e = 10 mm
Thus, the spring will stretch 10 mm when a 250 N force is applied.
The energy of nuclear fission is released as kinetic energy of the fission products and fragments, and as electromagnetic radiation in the form of gamma rays; in a nuclear reactor, the energy is converted to heat as the particles and gamma rays collide with the atoms that make up the reactor and its working fluid, ...
