HELPP You exert 500N of force on a wall but it does not move. You exert 5N of force on a marble and it moves 10 meters. In which situation has more work been done?​

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

How much energy must a refrigerator absorb from 225 g of water so that the temperature of the water will drop from 35°c to 5°c

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
