A hypothetical planet has a radius 2.7 times that of earth, but has the same mass. what is the acceleration due to gravity near its surface?

A 75 force is applied to the side of a crate resting on a level floor. The crate has a mass of 25kg. If the coefficient of static friction is. 15, is the 75 N force enough to make the crate accelerate? Explain why or why not.

A 4.3 kg bowling ball is initially at rest. If a 15 N force acts on it for 0.85 s, what is the final velocity of the bowling ball?

Two identical charges exert a force of + 0.034 N when they are 16 cm apart. What is the magnitude of each charge?

What does ΔP = QR mean in words?

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.

Two students are looking at a brightly lit full Moon, illuminated by the reflected light from the Sun. Consider thefollowing discussion between the two students about what the spectrum of moonlight would look like.
