PLEASE HELP I WILL GIVE BRALINEST How do friction and gravity affect motion? (Hint: Give an example of how EACH of them affects motion)

What force causes a feather to fall slower than a bowling ball?

What is the difference between mass and weight? (We have discussed this before in previous units)

On a cold day, when the air temperature is 0°c, you empty your lungs and take a deep breath, filling your lungs with 4.2 l of air. if you hold your breath until the temperature of the air in your lungs reaches 37°c, what is the volume of the air in your lungs at that point, assuming the pressure does not change?

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Which is not true about oxygen-17 and oxygen-18?
