What is the potential energy of the ball as it is half way through the fall, 20 meters high?

Chemistry

98 \times mass \text { joule } is the potential energy of the ball as it is half way through the fall, 20 meters high

<u>Explanation:</u>

Given data:

Height of the fall = 20 m

Given that the body is half-way through the fall, it is at above the ground 10 m

          \frac{1}{2} \times 20=10 \mathrm{m}

We need to find its potential energy (P.E)

Energy due to the body’s position is referred as potential energy. It means the energy when body is at rest. It can be expressed as below,

         \text { Potential energy }=m \times g \times h

Where

m – The body’s mass

g - Acceleration due to gravity  \left(9.8 m / s^{2}\right)

h - Height of the body

By substituting the given values, we get

           Potential energy =m \times 9.8 \times 10=98 \times m\ joule

Since the mass is not provided, just kept it.

Hydrogen bromide is found in volcanic gas. What is the chemical formula for<br> this compound?
ruslelena [56]

Answer:

Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.

bija089 [108]

Answer: B or C

Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.

A compound with a molar mass of 100.0 g/lol has an elemental composition of 24.0% C, 3.0% H, 16.0% O and 57.0%F. What is the mol
ch4aika [34]

If I made no mistake in calculation, the given answer must be correct...(tried my best)



elements   :                        carbon     hydrogen    oxygen       Fluorine

 composition [C]                     24             3                16                57

M r                                          12             1                16                19

(divide C by Mr)                       2               3                 1                  3


(Divide by smallest value)       2                3                  1                  3

(smallest value = 1...so all value remained constant)

Empirical formula : C2H3OF3


if molar mas = 100 g per mole, then

first step calculate Mr. of empirical formula:  [= 100]


Them molecular formula = empirical formula
