This is a "trick" question.
If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.
So the 100N weight's weight doesn't change in an elevator traveling at constant speed.

Answer: Kelvin ________________
Answer:
a blaring trumpet is sound energy
Explanation:
<span>Formula-
E = hc/ {wavelength}
Given in quation-wavelength=12.4 cm
We know the value of h and c.
h=6.626 * 10^-34 Js
c= 2.997 * 10^8 m/s
wavelength=12.4 cm converted to 0.124 m
E = [ 6.626 * 10^-34 Js * 2.997 * 10^8 m/s ] / 0.124 m
E = 1.60 * 10^-24 J
1.60 * 10^-24 J of energy of exactly one photon of this microwave radiation have.</span>
