What is the application of physics

What has more thermal energy? A giant, frozen iceberg or a swimming pool filled with boiling water? Explain.

A 1200 W refrigerator, a 1500 W electric frying pan, and a 200 W lamp are plugged into the same outlet in a 15 A, 220 V circuit. (these devices are in parallel when plugged into the same socket.) What current (in A) is drawn by refrigerator?

How do you calculate the moment of inertia of a flywheel

Maria's father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In this case, the stored chemical energy in the logs was changed into A) electrical energy. B) mechanical motion.

I'm big boi confused. A beam of light traveling in air enters a substance. If the angle of incidence is 35 ∘ and the angle of refraction is 25 ∘, what is the index of refraction of the substance? n1sin (theta) 1=n2sin (theta) 2 So would it be like 1.

You have two pendulums with cords that are exactly the same length. one is on earth (with an acceleration due to gravity of 9.81 meters/second2) and the other one is on the moon (with an acceleration due to gravity of 1.63 meters/second2).

The magnetic field is 0.0 2M from the wire is 0.1 T what is the magnitude of the magnetic field 0.0 1M from the same wire

A 747 jetliner lands and begins to slow to a stop as it moves along the runway. If its mass is 3.5 x 10 exponent 5 kg, its speed is 27.0 m/s and the net braking force is 4.30 x 10 exponent 5 N, (A) what id its speed 7.
