A golf ball at a certain point in the air had 22j of kinetic energy. The mechanical energy of the ball was 30j how much potential energy did the golf all have at that point

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

A15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°c to 175°c. what is the specific heat capacity of iron?
