Answer:
internal energy E 3716.35 j
cv = 12.47 J/K
S = 12.47 J/K
A = 0.29 J

Explanation:
given data:
Kr atomic number = 36
degree of freedom = 3
1) internal energy E = 
= 
2) 

3) 
4) A, Halmholtz free energy = E -TS = 37146.35 - 12.47*298 = 0.29 J
5)
Data:
The charge of a body depends on the amount of electrons it gains or loses. Q = n * e, where "Q" is charge, "n" is the number of plus or minus electrons, and "e" is the fundamental charge of an electron

<span>. To know if the body has gained or lost, we look at the signal of its charge, remembering that the electron is negative. The charge of the body is 4 μC (positive), so there is a lack of electrons!
Q = 4 </span>μC →



<span>
We have:

Hi pupil Here's your answer ::::

The sun Doesnt rotates as we know all . But it rotates with the wjole our Milky Way Galaxy. This movement is so slow that we cant even recognise that we are shifted.
This we know because we all had studied about the solar system and space.
By this study we can say that Sun Rotates.

Answer:
1.785 m/s
Explanation:
The momentum can be calculated using the expression below
M1 *V1 + M2 * V2 = (M1+M2) V3
M1= mass of van=9000 kg
M2= mass of car= 850kg
V3= velocity of entangled car
V1= Velocity of the van= 0
V2= velocity of the car= 5 m/ s
Substitute the values
(900×0) + (500×5)=( 900+500)× V3
2500=1400 V3
V3=2500/1400
V3= 1.785 m/s
Hence, velocity of the entangled cars after collision is 1.785 m/s
You measure the total distance the bike travels, and the total time it takes to travel that distance. You then divide the distance by the time
