How much energy is transported across a 1.00-cm^2 area per hour by a sinusoidal electromagnetic wave whose electric field has a maximum strength of 30.4 V/m? (ε0 = 8.85 × 10-12 C2/N • m2, μ0 = 4π × 10-7 T • m/A, c = 3.0 × 108 m/s)A) 0.44 nJ. B) 0.44 nJ. C) 0.44 mJ. D) 0.44 J.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .

Which best describes the difference between internal and thermal energy?

An object with a mass of 1.5 kg changes its velocity from + 15 m/s to +22 m/s during a time interval of 3.5 seconds. what impulse was delivered to the objects?
