Explanation:
The water cycle is based on three parts;
1. Evaporation
2. Condensation
3. Participation
Condensation:
It is the process in which water vapor changes into liquid water or in other words, it is the transition from the gaseous state to liquid state.
Precipitation:
It is the process in which any liquid or frozen water such as snow that forms in the atmosphere and falls back to the Earth
Condensation depends on temperature and pressure whereas precipitation depends on the temperature and the concentration of the solution.
This is an example of conduction
Answer:
v = 0.99 c = 2.99 x 10⁸ m/s
Explanation:
From the special theory of relativity:
where,
v = speed of travel = ?
c = speed of light = 3 x 10⁸ m/s
t = time measured on earth = 90 years
t₀ = time measured in moving frame = 6 months = 0.5 year
Therefore,
<u>v = 0.99 c = 2.99 x 10⁸ m/s</u>
Answer:
AC motor........A
Explanation:
Plato, an AC motor is much simpler than a DC motor. As alternating current passes through the coil, it becomes magnetized. Since the current is alternating, the north and south ends keep switching.
Answer:
-3m+7m = 4m
Explanation:
As he walks south, he is going down 3m (-3m). Then he walks up 7m (+7m).
You subtract the final position from the initial position to get displacement.
7m - 3m = 4m
