4. A contestant in a winter sporting event pushes a 45.0-kg block of ice across a frozen
lake as shown below with force of F = 51 N. What is its acceleration?

c.the charges if the proton and electron and gravity

it doesn't. it was imagined up in the middle ages.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
