Answer:
U
Explanation:
The first law of thermodynamics states that:
where
U is the internal energy of the gas, which represents the sum of the chemical and thermal energy stored in the atoms and molecules of the gas
represents the variation of internal energy
Q is the heat absorbed by the system
W is the work done by the system
So, the sum of the chemical and thermal energy stored in atoms and molecules is represented by U, the internal energy.
While no one knows why, astronomers do now know that the solar nebula has collapsed. Scientists believed that our Solar system was made when gas and dust cloud was being disturbed by an explosion of supernova. Due to pressure, this cloud collapsed.
The acceleration of the body in terms of the gravitational constant G is G.
According to Newton's law of universal gravitation;
F = Gm1m2/r^2
G = gravitational constant
m1 = mass of the first body
m2 = mass of the second body
r = distance between the two bodies
Substituting values to find the force on the two bodies;
F = G × 1 × 2/1^2
F = 2G
For the 2 Kg mass
F = ma
m = mass
a = acceleration
F = gravitational force
Hence,
2G = 2a
a = 2G/2
a = G

Explanation:
Answer:
3300J
Explanation:
Work done is the energy that is lost by the skater
Formula for workdone = 1/2*mV^2
m = 66kg
V = 10m/s
Work done = 1/2 * 66 * 10^2
= 3300J
