4
Explanation:
The number 4 in the hydrologic cycle depicts surface runoff.
The hydrologic cycle depicts the cyclic movement of water between different earth components.
It shows water in all its phases.
- From the attached image, runoff is depicted 4.
- Runoff is water that moves on the surface after precipitation.
- Number 1 is evaporation where water changes to vapor.
- Number 2 is condensation where the vapor cools back to liquid.
- Number 3 is precipitation where the liquid water is forced down under gravity.
- On the surface, the water runs as runoff.

The enthalpy difference between the reactants and the products is equal to the amount of energy absorbed from the surroundings. A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. ... Exothermic reactions heat up their surroundings while endothermic reactions cool them down.
You have this in Chemistry. It should be in physics, but never mind that.
A
d = 4 km due east. See note for part B.
t = 45 minutes = 3/4 hour
v = ??
d = v * t
4 = v * (3/4)
v = 4/(3/4) = 4 * 4/3 = 16/3 = 5 1/3
So his rate of travel is 5 1/3 km/hr due east. If you do not give the direction when it says velocity, you are wrong. Velocity has direction.
B
10 45 to 11 45 is 1 hour.
d = v * t
d = 6 km due south (this is actually a displacement which also has direction).
t = 1 hour
6 = v * (1)
6/(1) = v
6/(1) = v
v = 1 km/ hr due south
