Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the earth. It comes in many forms like rain, sleet, and snow. Along with evaporation and condensation.
Answer:
Final velocity = 16 m/s
Total distane travelled = 390 m
Explanation:
We can use equation of motion to solve this:
Answer: 15.6 metres
Explanation:
Given that:
length of wave (λ)= ?
Frequency of wave F = 28 Hertz
Speed of wave (V) = 437 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply V = F λ
Make λ the subject formula
λ = V / F
λ = 437 m/s / 28 Hertz
λ = 15.6 m
Thus, the length of the wave is 15.6 metres
The heat remains constant because there’s nothing to cool it down
A paper pinwheel is spinning in the wind.
Which statement is correct about the forces responsible for the rotation?
The components of gravity and the force of wind that point through the pivot are responsible for the rotation.
Only the perpendicular component of wind is responsible for the rotation, because gravity points downward.
Only the perpendicular component of gravity is responsible for the rotation, because wind points toward the pivot.
The perpendicular components of gravity and the force of wind are responsible for the rotation.
Answer:
Only the perpendicular component of gravity is responsible for the rotation because wind points toward the pivot.
Explanation:
A pinwheel is a plaything that is made up of paper that is designed to spin when the wind comes in contact with it. The paper is held fast to its axle by a pin which enables it to spin.
Therefore, if the pinwheel is spun anti-clockwise, it brings electrical energy, converting the wind energy and <u>only the perpendicular component of gravity is responsible for the rotation because wind points toward the pivot. </u>
