Answer:
120 Ns
Explanation:
The impulse exerted on an object is given by:
where
F is the force applied
t is the time taken
In this problem, we have:
F = 40 N
t = 3.0 s
So, the impulse acting on the boat is
If a ball is tossed straight up into the air, at what position is its potential energy the greatest? Question 3 options: When it
1 answer:
The ball has the greatest potential energy when it reaches the top of its flight. Option C is correct.
<h3>What is potential energy?</h3>The potential energy of a body or object is due to its position. The ball has the greatest potential energy when it reaches the highest point.
Where,
- potential energy
- mass
- gravitation acceleration
- height
Since the mass and gravitation acceleration is constant hence potential energy will be directly proportional to the height of the ball.
Therefore, the ball has the greatest potential energy when it reaches the top of its flight.

Explanation:
The magnitude of that other charge will be 9×10⁻⁵ C. The force on the charge is inverse of the distance.
<h3>What is Columb's law?</h3>The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The magnitude of that other charge is found as;
Hence, the magnitude of that other charge will be 9×10⁻⁵ C.
