If it took Ms. Oldham 37 seconds to lift a 400N (newtons) student up 15m, how much power did she use?

A geologist is studying a rock core sample of a hillside. Which would be the BEST evidence that this hillside was once covered by a body of water? A) The top of the core sample would contain fossils of shells.

Study the scenario. An object is at rest. At five seconds, someone comes over and pushes the object forward with a force of 10 N. Which of the following choices describes the force needed to keep the object in static equilibrium? 1.

How long does it take a 750-W coffeepot to bring to a boil 0.65 L of water initially at 13 ∘C? Assume that the part of the pot which is heated with the water is made of 360 g of aluminum, and that no water boils away.

A 125kg automobile with a tangential speed of 48.0 km/h follows a circular road that has a radius of 35.0m how large is the centripetal force

The Appalachian mountain range in the Eastern United States was once much taller than the Rocky mountain range in the Western United States.

Describe how lighting is just like you walking across a carpet and getting shocked

You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15∘ angle until its height has increased by h.

A 320-m length of wire stretches between two towers and carries a 120-a current. determine the magnitude of the force on the wire due to the earth's magnetic field of 5.0 * 10-5t which makes an angle of 60 ∘ with the wire.

Light acts like a. a wave. b. a particle. c. neither a wave nor a particle. d. both a wave and a particle.
