A) if energy is being absorbed, then more hydrogen bonds are being broken (melting). If energy is being released, more hydrogen bonds become fixed (freezing).
<span>b) during melting, hydrogen bonds get broken and movement can occur. During freezing, hydrogen bonds become fixed and water molecules cannot move as much.

For pressurized water reactors the coolant is not permitted to boil in the core of the PRW, however the coolant in boiling water reactors is permitted to do so in the core of BWR. Pressurized water reactors have an indirect cycle. Whereas, the boiling water reactors go through a direct cycle. Both are light water reactors.
Answer: 14.5 N
Explanation: NEED SCRATCH PAPER: A flower pot weighing 42.0 N (newtons) is hung above a window by three ropes, each making an angle of 15.0 degrees with the vertical. What is the tension in each rope supporting the flower pot?

Answer: Force is 4 times lower.
Explanation:
F1=γ*m₁m₂/r²
r*2=2r
F2=γ*m₁m₂/4r₂
F1/F2=4
F2=F1/4
Force = mass * acceleration. Therefore, given the force of 120 N and the mass of 46 kg:
120 N = 46 kg * acceleration
120 kg-m/s^2 = 46 kg * acceleration (in m/s^2)
acceleration = 120/46 = 2.61 m/s^2
