5. suppose a skydiver (mass = 75kg) is falling toward the earth. when the skydiver is 100m above the earth he is moving at 60m/s. at this point calculate the skydiver’s…….show your work and pe=mgh m= g= h=

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
