People playing a basketball game in a gymnasium make up a closed system with 17,125 J of energy. At the beginning of the game the system has 16,250

J of ME, and at the end it has 1,135 J of ME. How much of the total energy

was transformed into thermal energy during the game?

15,115 J of the total energy is transformed to thermal energy during the game.

Explanation:

From the law of conservation of energy, initial energy of the closed system E = final energy of closed system , E'

E = E'.

Let ME = initial mechanical energy of the system = 16,250 J and U = initial internal energy of the system and ME' = Final mechanical energy of the system = 1,135 J and U' = Final internal energy of the system.

So E = ME + U and E' = ME' + U'

We now find U and U'

Substituting E, ME, E' and ME' into the equations, we have

E = ME + U

17,125 J = 16,250 J + U

U = 17,125 J - 16,250 J

U = 875 J

E' = ME' + U'

17,125 J = 1,135 J + U'

U' = 17,125 J - 1,135 J

U' = 15,990 J.

The change in internal energy is also the change in thermal energy. So,

ΔU = U' - U

ΔU = 15,990 J - 875 J

ΔU = 15,115 J

So 15,115 J of the total energy is transformed to thermal energy during the game.

a electromagnetic waves

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
