You push a wall with a force of 50 N. If the wall doesn't move, what is the net force on you?

p. s. I'm pretty sure it's either 50 or 100 but I'm not quite sure

How does waters polarity affect living organisms

An object moving at 32m/s takes 8s to come to a stop. What is the object's acceleration?

So if an elephant is walking at 2.25 milers per hour (1 meter per second), slower then a normal human pace, and has a mass of 13,000 kg what would need to be the approximate momentum of a golf ball that has a mass of.

If Superman wants to slow down a fast car with speed 20 m/s and mass 1000 kg, how much force in N does he need to apply if he wants to get it down to zero within 3.2 seconds?

How does a low pressure system determine the weather in an area?

Molecules at room temperature move freely. What happens to the molecules when heat is removed until it freezes? Molecules group together Molecules slow down and contract Molecules speed up and expand Molecules move freely

A spring is used in a lab. It is vibrated at different frequencies and the wavelength is recorded. Using the graph of the data, what is the relationship found between frequency and wavelength? A) Frequency and wavelength are inversely related.

How do you describe the frequency of waves perceived by the observer from the moment the source appears to the moment it disappears?

What causes the stars to appear to move across the night sky?
