Question

Who has the zero kinetic energy?
Who has/have the most gravitational potential energy? Why? (1)
c)
Identify the change in energy form in the girl as she is moving
down the slide? (1)
d)
Can you identify various forms of energy shown in the picture? (1)
e)
What kind of energy is coming from the headphones?​

Answer 1

Answer:

a   At an object's lowest point, kinetic energy is zero/ maximum while potential energy is zero / maximum.

b   When the planet is closest to the Sun, speed v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases.

c    kinetic energy

e    Headphones act as transducers and convert audio signals (electrical energy) into sound (mechanical wave energy) via a moving diaphragm. Most headphones use magnets and conductive coils (electromagnetic induction) to move these diaphragms back and forth which, in turn, produce sound.

I can only answer these questions.  Hope it will help you.

Answer 2

Explanation:

identify the change in energy from in the girl is she is moving down the soil
