The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
temperature and precipitation
Explanation:
The temperature and precipitation a place receives determines the climate of a particular region.
Climate is the average weather condition over a place for an extended period of time.
- The temperature of a place is factor of the latitude of a region.
- Places at low latitude receives direct insolation from the sun.
- These areas have a very high temperature.
- Precipitation is the amount of water that falls under gravity.
- Temperature differences across different places cause the wind patterns we know.
- The humidity of a place depends on the precipitation.

In both places, there are 2 main seasons. The equator is warm all year round and the poles are cold all year round
Answer: alternative A.
Explanation: Deposition of sediments can happen in any place, because of water flows, wind, gravity, etc. It is possible to <u>analyze the sediments and find out the records of geologic history related to that place, being necessary to chose the most appropriate techniques to do so</u>.
