Answer:
x = 102.33 m
Explanation:
Given that,
Position where a forest ranger stands is 35 m above the ground. The angle of depression to the base of the fire is 20. We need to find how far from the tower is the fire.
Let the distance is x. We can find x using trigonometry as follows :
Hence, the fire is at a distance of 102.33 m from the fire.

Answer:
This statement is False.
Explanation:
This is because the molecules of gases are randomly traveling and they even sometimes collide with each other. So, it is true that they resist crowding but it is not always possible for the gas molecules to be as far apart as possible because of their random movements. This also makes it impossible for the gas molecules in the tank to be always at the maximum possible distance from its nearest neighbor.
However, the distance between the electrons is not due to random movements like gases. Electrons are placed at the distance from each other due to the forces of repulsion between them, as the same charged particles always repel each other. So, the dispersion of the electron on the copper ball is not due to the random distribution of electrons. However, they will be placed at a distance to each other due to the force of repulsion between them.
