Water is transported to a village in a tank pulled by a tractor.
Fig. 1.1 shows the tank being pulled by a tractor.
The combined mass of the tractor and the tank is 4100 kg when the tank is empty and 6500 kg when the tank is full of water.
The density of water is .
Calculate the volume of water in the tank when it is full.
volume = ______
At the start of the journey, the tractor and tank accelerate from rest along a straight, horizontal road. As their speed increases, one form of energy is decreasing.
State the name of the form of energy that is decreasing.
______
Explain what happens to this energy.
The village is located on a mountain at a vertical height of 850 m above the water supply. The gravitational field strength is .
Calculate the gravitational potential energy gained by the water as it is transported from the supply to the village.
energy gained = ______
