A measure of the force of gravity on an object is called

Is the alien theory a scientific claim? Why or why not?

Name the three general categories into which the elements are divided.

Siska hit a golf ball into the air with an initial velocity of 56 feet per second. The height h in feet of the ball above the ground can be modeled by h=-16t^{2}+56t, where t is the time in seconds after Sisika hit the ball.

A hoop and a disk have the same mass and radius. In addition, they both spin about their centers with the same angular speed. Is the kinetic energy greater than, less than, or equal to the kinetic energy of the disk? Explain

How are joules measured?

Why do marine west coast climates have much precipitation

Wright true or false: 1. A baseball has more momentum than a tennis ball traveling at the same speed. 2. A light ball has more inertia than a heavy ball 3. The less momentum a bowling ball has, the easier it is for that ball to knock down pins. 4.

The interference of two sound waves of slightly different frequencies produces

8. A force of 80 pounds on a rope is used to pull a box up a ramp inclined at 100 from the horizontal. The rope forms an angle of 330 with the horizontal. How much work is done pulling the box 25 feet along the ramp?

A raindrop has a mass of 5.4 * 10-7 kg and is falling near the surface of the earth. Calculate the magnitude of the gravitational force exerted (a) on the raindrop by the earth and (b) on the earth by the raindrop.
