Answer:
When it is cloudy, many of the sun’s rays never reach the Earth. It leads to cooler temperatures.
Explanation:
During the day, the sun warms the earth. When the sky is clear, more heat reaches the earth's surface . This leads to warmer temperatures.
However, when the sky is cloudy, a few drops of clouds reflect some of the sun's rays. As a result, less solar energy can reach Earth's surface, causing Earth to heat up more slowly. This leads to cooler temperatures.
If cloudy skies are forecast when forecasting daytime temperatures, expect lower temperatures than you would expect if clear skies were forecast.
Similarly, cloud cover at night has the opposite effect. When the sky is clear, the heat emitted from the earth's surface freely escapes into space, resulting in cooler temperatures.
However, when there are clouds, some of the heat from the earth's surface is captured by the clouds and returned to the earth. As a result, temperatures drop more slowly than when the sky is clear.

Answer:
The magnitude of Adams' force is 88 N
Explanation:
According to Newton's law ∑ forces in direction of motion is equal to
mass multiplied by the acceleration
There are two forces here the friction force and Adams' force
Adams' force is in direction of motion
Friction force is opposite to direction of motion
→ Friction force = μ R,
where μ is the coefficient of friction and R is the normal reaction force
of the boat
→ R = mg
where m is the mass of the boat and g is the acceleration of gravity
→ m = 47 kg , g = 9.8 m/s²
→ R = mg
Substitute the values in the rule
→ R = 47 × 9.8 = 460.6 N
→ Friction force = μ R
→ μ = 0.13 , R = 460.0 N
Substitute the values in the rule
→ Friction force = 0.13 × 460.0 = 59.878 N
→ ∑ Forces in direction of motion = mass × acceleration
→ F - Friction force = mass × acceleration
→ Friction force = 59.878 N , m = 47 kg , a = 0.6 m/s²
Substitute the values in the rule
→ F - 59.878 = 47 × 0.6
→ F - 59.878 = 28.2
Add 59.878 to both sides
→ F = 88.078 N ≅ 88 N
The magnitude of Adams' force is 88 N
The ocean zone that has the most sunlight is Mesopelagic. The correct option is D.
The Mesopelagic zone is a scope of sea depth that beginnings from 650 feet beneath the water's surface to around 3,280 feet underneath. Light entrances from the outer layer of the sea almost scatter at this area. The most widely recognized organic entities found in the mesopelagic zone are little fish, squid, and basic shellfish.
This region receives most of the sunlight.
Thus, the correct option is D.

The answer is D, Mesopelagic.
Answer: there would be no motion
Explanation:
There would be no motion,as the object get stuck
Answer:
Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.
