<span>Answer: 110.12 m/s </span>
We will use the formula A1V1 = A2V2
where 7.8 m/s is divided with 0.0085 m then multiply to 0.12 m, the result will
be 110.117 or 110.12 m/s. This is related to the continuity of fluid flow in
which as liquid moves horizontally, the same amount of liquid goes out as it comes in or the
liquid itself do not change as it moves but the speed does when the diameter changes.
19,600 Newtons (about 4,400 pounds).
On Earth only.
Different in other places.
Answer: force of gravity on the body due to height difference above the earth's surface
Explanation: as you increase the height of a body above ground, you do work against gravity in moving it from a point on the earth's surface to that point. So a body falling has a stored up gravito-potential energy which acts on it downward due to its mass, accelerating it downwards
Answer b): kinetic energy of the body
Explanation: the downward force produces an acceleration of magnitude 9.81m/s2 downwards which means an increasing velocity. This increasing velocity means the kinetic energy of the body is increasing (kinetic energy is proportional to velocity of the body squared)
Energy from the sun is referred to as solar energy.
So energy from the sun is solar energy.
hope it helps!!!
