Explanation:
Given that,
Mass of a body, m = 1 kg
Force constant, k = 16 N/m
We need to find the angular frequency and the frequency of oscillation.
(a) The angular frequency of a body is given by :
(b) The frequency of oscillation is given by :
Hence, this is the required solution.
Answer:
Number of electrons, n = 6
Explanation:
Total charge in a single droplet,
The measured charge of any single droplet,
Let n is the number of excess electrons are contained within the drop. According to the quantization of charge :
n = 6
So, there are 6 electrons contained within the drop. Hence, this is the required solution.
Answer:
Explanation:
The volume of the balloon can be find compared the force in each cases so:
reduce 25% from 74kg
So the net force uproad on the balloon is
Now the density of the both gases air and helium are different however the volume is the same change offcorss the mass so:
