Why are plate tectonics a theory?

Four particles, one at each of the four corners of a square with 4.5-m-long edges, are connected by massless rods. the masses of the particles are m1 = m3 = 4.0 kg and m2 = m4 = 7.0 kg. find the moment of inertia of the system about the z axis.

A cannonball is launched from a cannon. Which of the following motion graphs for the cannonball will form a parabolic shape? acceleration vs. time None of the listed answers are correct vertical position vs. horizontal position velocity vs. time

Which wave causes the medium to vibrate only in a direction parallel to the wave's motion?

the acceleration of a freely falling body is about 10m/sec/sec. if the ball is dropped from the top of a building what would its velocity be after 2 seconds?

The average distance to the stars that make up the constellations in the night sky around the sun is about

What happen when a light from the sun passes through any type of matter

A projectile is launched at ground level with an initial speed of 53.0 m/s at an angle of 35.0° above the horizontal. It strikes a target above the ground 2.50 seconds later.

A 2650-lb car is traveling at sea level at a constant speed. its engine is running at 4500 rev/min and is producing 175 ft-lb of torque.
