Answer:
= 500 Hz
Explanation:
A Period of a wave is the time taken for one complete oscillations by the wave particles. It is measured in seconds.
Frequency on the other hand is the number of complete oscillations covered by a wave in one second. It is measured in Hertz.
Period is the inverse of frequency.
That is; Period, T = 1/ frequency, f
T = 1/f and thus; f = 1/T
Therefore;
f = 1/0.002 seconds
= 500 Hz
There actually three assertions here: one in A and two more in B.
All three assertions, as well as the reasoning described in this mess, are all False.
The correct choice from the list is e), but that doesn't even describe the complete Falseness of this disaster.
Explanation:
Given
mass (m) = 2 kg
acceleration due to gravity (g) = 10 m/s²
Force (F) = ?
We know
F = m * a
= 2 * 10
= 20 N
The force is 20 N.
Hope it will help :)❤
