Answer:If the kinetic and potential energy in a system are equal, then the potential energy increases. ... Stored energy decreases. Energy of motion decreases. Total energy decreases
Explanation:
Here are two leading theories to explain how the first galaxies formed. The truth may involve a bit of both ideas.
One says that galaxies were born when vast clouds of gas and dust collapsed under their own gravitational pull, allowing stars to form.
The other, which has gained strength in recent years, says the young universe contained many small "lumps" of matter, which clumped together to form galaxies. Hubble Space Telescope has photographed many such lumps, which may be the precursors to modern galaxies. According to this theory, most of the early large galaxies were spirals. But over time, many spirals merged to form ellipticals.
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
Answer:
a) E = V/L x^
b) R = ρL/A = ρL/π(d/2)^2 = 4ρL/πd^2
c) I = V/R x^ = V/(4ρL/πd^2) x^ = πd^2*V/4ρL x^
d) J = I/A = [πd^2*V/4ρL x^]/π(d/2)^2 = V/ρL x^
e) ρJ = ρ(V/ρL x^) = V/L x^ = E
In short, I’d say the answer is Dry Sand.
In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.
