Answer: d. thunderstorms
The option <span>blizzards can be excluded as it is clearly not related to the evaporation. Floods can happen if the condensation rate high, not evaporation. Sometimes the cloud that carries water is just blown up by the wind so the evaporation does not happen in that place.
Thunderstorms happen more in summer because the rate of evaporation and condensation is increased.</span>
The mechanical advantage of a machine is the ratio of the force produced by the machine to the force applied to it. Therefore, we may calculate the applied force using:
Mechanical advantage = force by machine / force applied
6 = 2 / force applied
Force applied = 1/3
Thus, the distance that the effort must move will be 1/3 inch
Answer:
By using Pythagoras Formula
Explanation:
Measure the distance man is sliding. “It will be c”
Measure the distance of between the tower and a post with which wire is attached. It will be “b”
Then apply Pythagoras Formula c2=a2 + b2 and solve it.
It will give the height of tower.
Answer:
The neutral wire and the ground wire.
Explanation:
The black wire is the hot wire
The neutral wire provides the return path for the current provided by the hot wire.
The ground wire is connected to any metal parts in an appliance for example microwave.
A standard electrical outlet has three wires connected to it: the hot, the neutral, and the ground. There is no potential difference between the neutral wire and the ground wire.
Using the mirror formula.
1/v + 1/u = 1/f
1/9.5 + 1/3.2 = 1/f
1/f = 3.2 + 9.5 / 9.5 * 3.2
1/f = 4.82 cm
Radius = 2f
Radius = 2 x 4.82
Radius = 9.64 cm
