The weakest of the four fundamental forces is the gravitational force.
Answer: Option D
<u>Explanation:</u>
The four basic forces are responsible for all kind of interaction in the universe: The gravitational force, electromagnetic force, strong nuclear and the weak nuclear force. Where the electromagnetic force has been given the strength value of 1, the gravitational force ranged from 10 to -40.
Comparing to other 3 fundamental forces, gravity draws the weakest impact on the object and acts the strongest in the absence of other forces. When we place a small magnet near to an iron nail, it gets attracted towards the magnet in a second, leaving the influence of gravity. This is just a single example, there are huge number of examples to prove the worth of this statement.
Answer:
Beats are the difference in frequency.
(a) is correct option.
Explanation:
Beat :
Beat is the difference of the frequency of two waves.
The difference in frequency is equal to the number of beat per second.
Amplitude :
Amplitude of the wave is the maximum displacement.
Frequency :
Frequency is the number oscillations of wave in per second.
Intensity :
Intensity is the power per unit area.
Hence, Beats are the difference in frequency.
