A change in color, a formation of gas or bubbles, temperature change.
<h2>
Velocity at maximum height is zero.</h2><h2>Acceleration at maximum height is 9.81 m/s² downward.</h2><h2>Acceleration when it just hits the ground is 9.81 m/s² downward.</h2>
Explanation:
For a ball thrown vertically upward, the velocity at maximum height is zero.
Acceleration is a constant for a ball thrown vertically upward, its is acceleration due to gravity.
Acceleration at maximum height is 9.81 m/s² downward.
Acceleration when it just hits the ground is 9.81 m/s² downward.
B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
Our bodies emit heat, and nerve endings in our skin can detect it.
Our eyes can detect visible light, but our bodies don't emit that.
Answer:
B) 12 m
Explanation:
Gravitational potential energy is:
PE = mgh
Given PE = 5997.6 J, and m = 51 kg:
5997.6 J = (51 kg) (9.8 m/s²) h
h = 12 m
