The period of the ball in simple harmonic motion is 0.634 s.
<h3>What is period?</h3>
Period can be defined as the time ( in seconds) taken for a body to complete one oscillation.
To calculate the period of the ball in SHM, we use the formula below.
Formula:
- T = 2π√(m/k)............... Equation 1
Where:
- T = Period of the ball
- m = mass of the ball
- k = spring constant
- π = pie
From the question,
Given:
- m = 2 kg
- k = 196 N/m
- π = 3.14
Substitute these values into equation 1
- T = 2(3.14)√(2/196)
- T = 6.28√(0.010204)
- T = 0.634 s
Hence, The period of the ball in simple harmonic motion is 0.634 s.

Answer:
67 kPa
Explanation:
Given that,
Initial volume, V₁ = 25 cm³
Initial pressure, P₁ = 100 kPa
Final volume, V₂ = 15 cm³
We need to find the change in pressure of the gas. The relation between the volume and pressure of a gas is given by :
or
= 167 kPa
The change in pressure,
= P₂ - P₁
= 167 kPa - 100 kPa
= 67 kPa
Hence, the correct option is (a).
