As the comet slows down, energy is lost from the system. As the kinetic energy of the system increases, the gravitational potential energy of the system decreases. As the comet's kinetic energy increases, the gravitational potential energy of the system also increases. As the comet slows down, the kinetic energy of the system decreases. External work must be done on the system to speed up the comet.

what are the statements? x

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

so easy. just google the electromagnetic waves and it’ll pop up.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
