Few Examples of Kinetic Energy

The following are typical examples of kinetic energy:

A wrecking ball used to demolish a building through utilization of the kinetic energy it possesses in motion.

Conversion of liquid water to steam, by virtue of the fast movement of the molecules of the liquid upon agitation

A golf ball after being struck off the tee

An asteroid falling towards Earth at incredible speed

A downhill skier traveling down a hill

The flow of a river

An airplane in motion (possesses a tremendous amount of kinetic energy. This is because the mass of the airplane and the velocity at which it moves are enormous)

Explanation:

Answer:

"The battery in the car has potential energy in the form of chemical energy. As the car is turned on and moves, this potential energy becomes kinetic energy."

Answer:  1 cm = 100m

Explanation:  Centi- is the prefix used to designate 0.01 (one hundredth) of something.  1 cm means 0.01 m.

1 cm = 100 m  is NOT a correct conversion factor. Option C is correct.

The conversion factors are the factors that re-use to convert some values from unit to unit of another value like from centimeter to meter from meter to kilometer from milligram to gram.

In one centimeter it is the suffix used to denote it is the one by hundred value of the on meter or which is equal t one meter so, 1cm = 0.01 meters as it is the 1/100 part f the one-meter distance.

Therefore, Option C is correct. 1 cm = 100 m  is NOT a correct conversion factor.

1.6 grams of oxygen will react with 2.4 grams of magnesium.

Explanation:

Given:

2.4 grams of magnesium.

The reaction between magnesium and oxygen:

[tex]2Mg+O_2\rightarrow 2MgO[/tex]

To find:

The mass of oxygen required to react with 2.4 grams of magnesium.

Solution:

The mass of magnesium = 2.4 g

Moles of magnesium =[tex]\frac{2.4 g}{24.305 g/mol}=0.0987 mol[/tex]

[tex]2Mg+O_2\rightarrow 2MgO[/tex]

According to the reaction, 2 moles of magnesium reacts with 1 mole of oxygen, then 0.0987 moles of magnesium will react with:

[tex]=\frac{1}{2}\times 0.0987 mol=0.04935\text{mol }O_2[/tex]

Moles of oxygen required = 0.04935 mol

The mass of 0.04935 moles of oxygen :

[tex]=0.04935\times 31.999 g/mol=1.579 g\approx 1.6 g[/tex]

1.6 grams of oxygen will react with 2.4 grams of magnesium.
