Not going to type it all for you but possible weight difference has a major roll in answering this
because that is the right equation
Calculate them and you will know why the correct answer is D
Frequency = 1/time period = 1/0.05 = 20s^-1.
Explanation:
X-rays are almost same as the visible light as they both electromagnetic waves with same speed. However, the only difference the energy level of photons of X- rays are higher than those of the visible light. This is because the frequency of the X-rays are higher.
E=
h= plank's constant and \nu is the frequency of the wave. So, higher the frequency higher will be the energy of the wave.
Answer:
Yes.
Explanation:
With no extra force acting upon it, it is a still object.
Like laying flat on a bed of nails. With no force pushing you down besides gravity, you will not cut yourself.
