The distance of motion, or displacement, along a fault during an earthquake is known as:

You throw a baseball horizontally, and Jill catches it. Neglect air resistance. The energy transformation that occurs during the catch is A) kinetic E ⇒ chemical E. B) kinetic E ⇒ thermal E. C) chemical E ⇒ kinetic E. D) thermal E ⇒ kinetic E.

As an object moves downhill, some of the energy is A. kinetic and some is potential B. kinetic C. lost due to friction D. potential I tryed C! Its not right

5. A 1052 kg truck, starting from rest, reaches a speed of 20.0 m/s in 6.20 s. a. What is the average acceleration of the truck? b. What is the magnitude of the average net force on the truck during the 6.20 s?

A fan is to accelerate quiescent air to a velocity of 12.5 m/s at a rate of 9 m3/s. Determine the minimum power that must be supplied to the fan. Take the density of air to be 1.18 kg/m3.

Which of the following best describes transverse waves

What are the arrangement of resistors in series

A pilot flies horizontally at 1300 km/h, at height h! 35 m above initially level ground. However, at time t! 0, the pilot begins to fly over ground sloping upward at angle u! 4.3° (Fig. 2-38).

A helicopter flies 30 km 30 degrees north of east, drops of the supplies to a research team; it then heads 50 degrees north of west traveling 70 km to drop the supplies to a filming crew. What is the resultant displacement of the helicopter?

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below).
