If a 50kg boulder is 100m off the ground and a 25 kg boulder is 100 m off the ground, which has a stronger gravitational force pulling it towards Earth?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

How do you tell if someone actually cares about you? and just say they do?
