The value is
Explanation:
From the question we are told that
The mass of the car is
The acceleration is 
Generally the net force applied on the rope is mathematically represented as

Here W is the weight of the car which is evaluated as
=> 
=> 
Generally the net force can also be mathematically represented as
So

=> 
=>

Answer:
r₂=0.1 m
Explanation:
Given that
r₁= 10 m , β₁ = 20 dB
At r₂ ,β₂= 60 dB
As we know that intensity level of sound given as



10² x 10⁻¹² = I₁
I₁=10⁻¹⁰ W/m²


10⁶ x 10⁻¹² = I₂
I₂ = 10⁻⁶ W/m²
I₁=10⁻¹⁰ W/m²
P = I A
P=Power ,I =Intensity ,A=Area


r₂=0.1 m
Answer:
Part a)

Part B)

Part c)

Explanation:
Part a)
As we know that

so we will have





Part B)
Angular speed of the yo-yo

so we have


Part c)
Tangential acceleration is given as
