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:
14.6 m/s
Explanation:
Momentum is conserved in the north:
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
After the collision, they stick together, so v₁ = v₂ = v.
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v₂
(980 kg) (0 m/s) + (1500 kg) u = (980 kg + 1500 kg) vᵧ
1500 u = 2480 vᵧ
Momentum is conserved in the east:
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v₂
(980 kg) (22.3 m/s) + (1500 kg) (0 m/s) = (980 kg + 1500 kg) vₓ
21854 = 2480 vₓ
vₓ = 8.81 m/s
The angle of v is 45.0°, so vᵧ = vₓ.
1500 u = 2480 (8.81 m/s)
u = 14.6 m/s

Answer:
Tendons connect muscle to bone. These tough, yet flexible, bands of fibrous tissue attach the skeletal muscles to the bones they move. Essentially, tendons enable you to move; think of them as intermediaries between muscles and bones.
