What are the two factors that determine the strength of the gravitational force between two objects?

a.
size and speed

b.
density and mass

c.
mass and distance

d.
mass and temperature

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?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.
