How does the length of a string affect the average time of a pendulum swing?

In the water cycle, which state of matter has the particles closest together?

Explain why this is, using the formula for calculating potential energy in your explanation (PE=mgh)

An ant on a picnic table travels 20 cm eastward then 25 cm northward 5 cm westward and finally 10 cm northward what is the ants displacement relative to its original position

Why can't ice transfer coldness into another substance?

Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 2.1*104 m/s when at a distance of 2.5*1011 m from the center of the sun, what is its speed when at a distance of 4.9*1010 m.

How much energy (in joules) is required to evaporate 0.0005 kg of liquid ammonia to vapor at the same temperature?

It is 5.5 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h (which uses up energy at the rate of 700 W), or you could walk it leisurely at 3.0 km/h (which uses energy at 290 W).

The largest volcanic structures on venus are called:

a block with a mass of 3 kg is swung on a cord in a horizontal circle with a radius of 2m. the speed of the block is 6m/s^. the magnitude of the acceleration of the block is most nearly

A scientific theory becomes more widley accepted as it explains more and more?
