What happens when a proton is brought near another proton?

Which statements are explained by Newton's law of universal gravitation? A) Heavier objects fall faster than lighter objects. B) The strength of Earth's gravity decreases as an object gets farther from Earth.

In a football game, the running back takes a handoff and begins running toward midfield at 3.21 yards/s. As he moves through his linemen, he accelerates at a rate of 1.71 yards/s^2 to a velocity of 7.54 yards/s before he is tackled.

Nanotechnology and microtechnology devices are both very tiny. However, one property of nanotechnology distinguishes it from microtechnology. What is this unique property? Nanotechnology can create new products.

Whats the formula for distance if i have time, acceleration and speed

A person wishes to accelerate an object upward uniformly. Which one of the following choices must be true of the force, F, provided by the person onto the object? W represents the magnitude of the gravitational force acting on the object.

When blue light of wavelength 450 nm falls on a single slit, the first dark bands on either side of center are separated by 45.0

An object is moving east, and its velocity changes from 65 m/s to 25 m/s in 10 seconds. Which describes the acceleration? 4 m/s2 in negative acceleration 4 m/s2 in positive acceleration 9 m/s2 in positive acceleration 9 m/s2 in negative acceleration

Two students walk in the same direction along a straight path at a constant speed-one at 0.90 m/s and the other at 1.90 m/s. •How far would the students have to walk so that the faster student arrives 5.50 min before the slower student? A.) 460s B.

During the process of accretion, each planet-in-the-making, or proto-planet, grew in size and mass. The amount of gravity for the proto-planets is best represented by which graph?
