Apples of diameter 12cm are picked from a tree and cooled in a stream of cold water to reduce their metabolism so that they store longer. Consider a stream of water at 5°C and a velocity of 0.04 m/s flowing over an individual apple. If each cooling tank contains 1000 apples, and assuming the apple has an initial temperature of 25°C, how much energy (W) do you need to supply the tank to keep it cool (based on the amount of thermal energy being removed from each apple according to the initial conditions)?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
