Answer:
138.46 ft
Explanation:
When the ball is dropped until the moment it hits the water, the ball moves in a uniform acceleration motion. Therefore, the equation that describes the movement of the ball is:
Where X is the distance that the ball has fallen at a time t. 
is the initial velocity, which is 0 ft/s as the ball was simply dropped. 
is the initial position, we will say that this value is 0 in the position where the ball was dropped for simplicity, and it increases as the ball is falling. Now, we replace x with 16 feets and solves for t:
The velocity that the ball will have at the moment the ball that the ball hits the water will be:
The time that will take the ball to reach the bottom from the top of the lake will be t = 5.3s - 1s = 4.3s. And as the ball will travel with constant velocity equal to 32.2 ft/s^2, the depth of the lake will be:
The freshwater reservoirs on earth are ranked by volume, with the one with the biggest volume at the top is-
1. ice caps; 2. groundwater; 3. lakes; 4. rivers.
<h3>Explain the freshwater reservoirs on earth?</h3>
The atmosphere, the earth's surface, and the earth's interior are the three main locations where water can be kept.
- Oceans, glacier ice, underground, lakes, soil humidity, living organisms, atmospheric atmosphere, and rivers are examples of these reservoirs, which are used to store water.
- There is an estimated 1.386 billion km3 (330 million cubic miles) of water on Earth, of which 97.5% is salt water and 2.5% is fresh water.
- Only 0.3% of a fresh water is liquid at the surface.
- More than 70% of freshwater is utilized for agriculture in the majority of the world's areas.
- An estimated 50% increase in agricultural output and a 15% increase in water flows are needed by 2050 to feed a globe of 9 billion people.
Thus, the freshwater reservoirs on earth are ranked by volume, with the one with the biggest volume at the top is-
- 1. ice caps
- 2. groundwater
- 3. lakes
- 4. rivers

There's a normal amount of condensation when a AC is running. If it's dripping on the floor, look for the white PVC pipe that is supposed to be there to drain it. If it's coming from inside the unit, call a repair person.
Answer:
B= 55.6×10^(-7) Tesla
Explanation:
B= μoI/(2πr)
B: magnetic field strength
μo: permeability of free space and is equal to 4π×10^(-7) T.m/A
r: distance from the wire
I : current in the wire
B= (4π×10^(-7)×125)/(2π×4.5)
B= 55.6×10^(-7) Tesla
Potential energy is the answer
