3. A 50.0kg diver jumps from a ledge 8.0m above a swimming pool and comes to rest 2.0m below the surface of the water. How fast is she going before she hits the water? What is the average force of water resistance that brings her to stop. If the energy of her dive goes into heating the water which has a volume of 2.5m ^ 3 how much warmer will the water become? The specific heat of water is 4186 J/(kg.^ C)Hey

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
