no easy sooooo easy like cmon now
Answer:
Waves and surface currents are wind-generated. The atmosphere pushes the ocean surface along. But as the ocean moves, heat is redistributed and eventually tossed back into the atmosphere. The exchange of heat influences the pressure field in the atmosphere, which modifies the wind field.
Answer:
The maximum height reached by the ball is 20.4 m.
Explanation:
We have,
Mass of a ball is 15 kg
It is thrown straight upward with a speed of 20 m/s.
It is required to find the maximum height reached by the ball. Let the maximum height is h. As energy is conserved, the potential energy at the ball's highest point is equal to the kinetic energy when it is thrown. So,
So, the maximum height reached by the ball is 20.4 m.
The solution for this problem is computed by through this formula, F = kQq / d²Plugging in the given values above, we can now compute for the answer.
F = 8.98755e9N·m²/C² * -(7e-6C)² / (0.03m)² = -489N, the negative sign denotes attraction.
