A spring scale reads 20 N as it pulls a 4 kilogram box across a table. What is the magnitude of the force exerted by the mass on the spring scale, if the frictional force is assumed to be equal to zero?

What are the base units in the metric system?

A bicyclist rides forward with a positive acceleration. How would her acceleration be different if she had less mass?

At Zion National Park a loud shout produces an echo 34.50 s later from a colorful sandstone cliff. How far away is the cliff?

Recently, some information about a distant planet was learned. It has a radius of 6000000 meters, and the density of the atmosphere as a function of the height h (in meters) above the surface of the planet is given by δ (h) =

Which of the following is not a good approximation of the relationship between independent and dependent variables? A. independent: first, dependent: next B. independent: input, dependent: output C. independent: cause, dependent: effect D.

A force is applied to a 13.0 kg wagon to pull it down the sidewalk at a constant speed. The coefficient of kinetic friction is 0.65. Considering the resulting frictional force, what is the magnitude of the applied force?

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planers in orbit around the Sun.
