What doesnt change despite what planet you're on

The minimum energy needed to eject an electron from a sodium atom is 4.41 x 10-19 j. what is the maximum wavelength of light, in nanometers, that will show a photoelectric effect with sodium?

A car with an initial velocity of 16.0 meters per second east slows uniformly to 6.0 meters per second east in 4.0 seconds. What is the acceleration of the car during this 4.0-second interval?

Wich theory focuses on how people are different than animals

The acceleration, as related to the net force acting on an object, is

What us fission and fusion

A man runs at a velocity of 6.2 m/s for 11.5 minutes. When going up and increasingly steep hill, he slows down at a constant rate of 0.25 m/s^2 and comes to a stop. How far did he run?
