A tennis ball is dropped from 1.16 m above theground. It rebounds to a height of 0.866 m.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s

Answers

Final answer:

Using the principles of free fall motion, it can be determined that a tennis ball dropped from a height of 1.16 meters would hit the ground with a velocity of 4.8 m/s.

Explanation:

The objective here is to calculate the initial velocity of the tennis ball just before it hits the ground. This is a physics question related to free fall motion. We will use the equation of motion, v^2 = u^2 + 2as, where 'v' is the final velocity, 'u' is the initial velocity, 'a' is the acceleration, and 's' is the distance. In our case, the initial velocity (u) is 0 because the ball is dropped, not thrown downwards.

The acceleration (a) is the acceleration due to gravity, which is -9.8 m/s² (it's negative because it acts downwards). The distance (s) will be the drop height, which is -1.16 m (it's negative because we're considering downwards as negative direction). Therefore, the equation becomes (v)^2 = 0 + 2*(-9.8 m/s²)*(-1.16 m). Solving this we get v = √(2*9.8*1.16) m/s = 4.8 m/s. So, the tennis ball hits the ground with a velocity of 4.8 m/s.

Temperature and silica content determine the of magma.

Answers

I think the correct answer is that they can determine the viscosity of the magma. The viscosity of a magma is largely controlled by the temperature, composition and the gas content. Also, silica content can define a magma type. It is said that higher silica content magma has a higher viscosity than those with lower silica content.

When an electric current is passed through water during the process of electrolysis two gases are formed one gas has a boiling point of -183 c and the other has a boiling point of -253 change or a chemical change occurred explain had a physical change or a chemicial change occurred explain?

Answers

There is a chemical change because the liquid water, after passing an electric current, produces hydrogen and oxygen gases. This is a reaction. The molecular component of eater has been broken down into two. These two gases have different structures compared to water.

Sunlight is a form of electromagnetic energy.
a. True
b. False

Answers

It is true that sunlight is a form of electromagnetic energy. Electromagnetic energy is a form of radiant energy that released by electromagnetic radiation. One example of an electromagnetic radiation is the visible light. And visible light can be radio waves, infrared light and X - rays. The rays of the sun are a form of visible light. It has an electromagnetic radiation of UV (ultra violet) rays. That is why the radiation at day is greater than at day due to sun’s rays.

When used as an energy source in a nuclear power plant, uranium is burned in a similar way as one would burn wood or coal for energy. a. True
b. False

Answers

False because nuclear fission is used on uranium in nuclear power station and this reaction is continuous since a neutron hits a uranium atom and splits it. Then 2-3 neutrons are released which continues the cycle or hitting other uranium atoms. If this reaction isn't contained, it could get out of control and become a nuclear bomb. So it can't be burned like wood nor coal.
Hope this is helpful.

The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by _________.Coulomb
Oersted
Faraday
Ampere

Answers

This discovery was made by Ampere. He further investigated the discovery made by Oersted. Ampere lead to the realization that two parallel wires that carry current exert a force upon each other. He further discovered that when the currents in two wires are in the same direction they are attracted to each other while when the currents are in the opposite directions they are attracted.

Typically, water runs through the baseboard copper tubing and, therefore, fresh hot water is constantly running through the piping. However, consider a pipe where water was allowed to sit in the pipe. The hot water cools as it sits in the pipe. What is the temprature change, (ΔT), of the water if 193.0 g of water sat in the copper pipe from part A, releasing 2665 J of energy to the pipe? The specific heat of water is 4.184 (J/g)⋅∘C.
