What is the transfer of thermal energy from one material to another by electromagnetic waves?

Is the amount of energy in a sound wave per unit of time and is also related to the loudness of a sound.

How can the newly discovered form of matter time crystals, how can they vibrate without any outside force? Doesn't that defy the currently accepted laws of physics?

A grating whose slits are 3.2x10^-4 cm apart produces a third-order fringe at a 25.°0 angle. What is the wavelength of light that is used?

Let n represent the number of similar resistors in a circuit. Each resistor has a resistance of r. When the resistors are connected in parallel the circuit has a total resistance of R.

What is the momentum of a 0.145 kg baseball traveling at 40.0 m/s

To analyze the motion of a body that is traveling along a curved path, to determine the body's acceleration, velocity, and position. A motorcyclist travels around a curved path that has a radius of 250 ft.

You walk with a velocity of 2 m/s north. You see a man approaching you, and from your frame of reference he has a speed of 3 m/s to the south.

Imagine you are holding an apple. Does this apple have energy? how do you know?

Explain how inertia and the shape of a loop counteract the force of gravity to keep riders from falling out when a roller coaster goes through a loop traveling upside down
