Answer:C
Explanation:
Given
mass is at
mark
mass is at
mark
Scale is Pivoted at
For scale to be in equilibrium net torque must be equal to zero
Taking ACW as positive thus
Therefore a net torque of 0.04 g is required in CW sense which a mass can provide at a distance of
from pivot
therefore in meter stick it is at a distance of
Answer:
The correct options are:
B) They have the same wave speed as visible light
D) They have a lower frequency than gamma rays.
Explanation:
B) Ultraviolet rays, commonly known as UV rays, are a type of electromagnetic ways. As electromagnetic waves, in the layman's term, are all kinds of life that can be identified, all electromagnetic waves (UV rays, visible light, infrared, radio etc) all travel with the same velocity, that is the speed of light, given as v = 3 × 10⁸ m/s
D) The frequency of all electromagnetic rays can be found by electromagnetic spectrum (picture attached below).
We can clearly see in the picture that the frequencies of UV rays lie at about 10¹⁵ - 10¹⁶ Hz which is lower than the frequency of Gamma ray, which lie at about 10²⁰ Hz.
