The burning of coal is used to heat water in a coal-burning power plant. TRUE or FALSE?

Explain 2 reasons why reactions take place faster at high temperature

If the buoyant force is less than an object's weight, the object?

A 1000 kg car crashed into bearer. the car changed speed from 30 m/s to 20 m/s in 2 seconds. What force did the bearer apply to stop the car?

When the only force affecting an object is gravity, that object is

an object is shot straight upward from sea level with an initial velocity of 250 ft/sec. a) assuming that gravity is the only force acting on the object, give an upper estimate for it's velocity after 5 seconds has elapsed.

What is the average speed of an object with a total distance traveled of 45 meters in 50 seconds

Some machines do not multiply the force that is applied to them

An automotive research facility is testing a new design on bumpers to determine the force at which it will break.

Gravity is greater when there is

A gas has a volume of 6 L, a temperature of 70 degrees C, and a pressure of 2 atm. If the gas is compressed to a volume of 4 L, and the pressure increases to 5 atm, what will be the new temperature of the gas?
