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)
Answer:
200 N
Explanation:
For a body moving in uniform circular motion, the force acting on it will be <em>centripetal force</em> and its direction is <em>radially inward</em> , pointing to the center.
The radially inward acceleration, or the centripetal acceleration is given by :
a = v² / r
where v is the speed at which the body is moving and r is the radius of the circle
Given-
m = 55kg
v = 14.1 m/s
r= 55m
We know that F = ma
⇒ F = m ( v²/ r )
⇒ F = 55 x 14.1 x 14.1 / 55
⇒ F =14.1 x 14.1 = 200 N
∴ <em>The force acting is 200 N</em>.
