During an autumn storm, a 0.012 kg hail stone traveling at 20.0 m/s made a 0.20 cm deep dent in the hood of Darnell’s new car. What average force did the car exert to stop the hail storm?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

Match each scenario to the form of energy it represents

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
