alukav5142 [94]

Answer:

Total height (s) = 176.4 m

Explanation:

Given:

Initial velocity (u) = 0 m/s

Time taken (t) = 6 sec

Acceleration due to gravity = 9.8 m/s²

Find:

Total height (s)

Computation:

s = ut + [1/2]gt²

s = (0)(6) + [1/2][9.8][6²]

s = 176.4 m

Total height (s) = 176.4 m

5. Salt is often spread on roads during winter to prevent ice from forming. Do you think sugar would
Margaret [11]

Answer:

No because sugar is more sweet and it would not have the benefits of salt. Think of it like how people used to put salt on meat to preserve it. Would they put sugar on? No they would not because salt is a combination of things that sugar does not have.

Choose all the answers that apply. Power is calculated using ___.
antiseptic1488 [7]

Time , Work, Horsepower

Explanation:

In General, Power is defined as rate of doing work in physics.

1.) By work and Time, we can calculate power as follows,

                 Power = Work done per unit Time

                              = Work done / time

2.) From Horsepower we can directly get the power.

Horsepower (hp) is a unit to measure the  power, or the rate at which work is done, usually in  the output of engines or motors. There are many  types of horsepower. Two common ways of defining horsepower is being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.

which of the following are true for gravity? check all that apply. a. gravity is the force that holds objects on the surface of
Pani-rosa [81]
I believe answer the only correct answer is A. Only from thinking of how gravity works with the natural world around us. Plus answer d doesnt makes sense, and c is false. And lastly if you throw a bowling ball and soccer ball over a bridge at the same time, they will fall at the same rate, only thing that would delay them is if one had more air resistance than the other.

If a neutral atom has 25 protons in its nucleus. What is the number of surrounding electrons? Explain your answer.
Darina [25.2K]

Final Answer: 25 electrons

Explanation/Reasoning:

Hey there!

The number of protons in the nucleus of a neutral atom would have 25 protons. This is because it is equal to the atomic number.

The number of protons is equal to the number of electrons. So for our answer, the number of atoms in a neutral atom will be 25 electrons because the neutral atom had 25 protons.
