Explanation:
First, we need to calculate the constant force, that is, the ratio between the applied force and the rubber stretch due to the application of the force:
Now, we can know how far will an 18N force stretch the rubber. From (1):
The work done by the external force on the rubber is equal to its elastic potential energy:
Answer:
Explanation:
From the question we are told that
The moment of inertia is
The final angular speed is
The time taken is
The initial angular speed is
Generally the average angular acceleration is mathematically represented as
=>
=>
Generally the torque is mathematically represented as
=>
=>
Displacement can be zero so velocity is zero but the distance won’t be zero so speed won’t be zero
Wait what? I can’t understand. But here is what I understood. About how long does it take the Earth to make 1 revolution around the sun? Answer: 365 days
