Answer:
As r decreases, we lose gravitational potential energy - in other words, U G U_G UGU, start subscript, G, end subscript becomes more negative. Because energy is conserved, the velocity must increase, resulting in an increase in kinetic energy.
Explanation:
Answer:
The impulse delivered to the bungee jumper is 1.32 kN.s
Explanation:
The situation can be shown graphically as shown in the figure.
Impulse delivered to the bungee jumper = Area under the curve.
The curve represents a triangle and the area of traiangle = (1/2)base×height
The base of the triangle from the graph = 1.2 seconds.
The height of the triangle from the graph = 2.2 kN
Thus,
<u>Impulse = (1/2)×(1.2 seconds)×(2.2 kN) = 1.32 kN.s</u>
Answer:
Because the energy is waning
Explanation: hope this helps
The answer would be B. Magnetic fields are invisible they cannot be directly observed
Answer:
the water in the tea cup
Explanation:
Kinetic energy is the energy an object or particles possesses as a result of motion.
Liquid in higher temperature possesses more kinetic energy than liquid with lower temperature
