Answer:
E = 62.72 J
Explanation:
Given that,
The mass of a ball, m = 4 kg
The teacher raised the lawn bowling ball to a height of 1.6 meters before
they released it.
We need to find the gravitational potential energy of the ball.
We know that,
E = mgh
Where
g is acceleration due to gravity
So,
E = 4 kg × 9.8 m/s² × 1.6 m
E = 62.72 J
So, the gravitational potential energy of the ball is equal to 62.72 J.
Answer:
The times is 0.688 ms.
Explanation:
Given that,
Inductance L= 0.048 H
Capacitor C= 4\mu F
The current is initially maximum
We know that,
Where,
We need to calculate the time
....(I)
On integrating equation (I)
If
Put the value of
Hence, The times is 0.688 ms.
