The period of an oscillatory motion is defined as the
average of the time used in completing different numbers of oscillations
time to complete a number of oscillations
time to complete one oscillation
time taken to move from one extreme position to another

A moving object is said to have a uniform acceleration if its
displacement decreases at a constant rate
speed is directly proportional with time
velocity increases by equal amount in equal time intervals
velocity varies inversely with time

42.0N
37.0N
32.0N
10.0N
Correct answer is D
F = \(\frac{mv - mu}{1} = \frac{21 - 16}{0.5} = 10N\)
The tendency of a body to remain at rest when a force is supplied to it is called

4N
5N
48N
60N
Correct answer is C
R.D = \(\frac{m}{m - m_2} = 5 = \frac{60}{60 - m_1} = \frac{240}{5} = 48N\)
