Answer:
The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB) Intensity of sound results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.

Answer:
1. 6.37 KJ
2. 3.185 KJ
Explanation:
Gravitational potential energy is a form of potential energy with respect to the force of gravity.
Gravitational potential energy = mass x acceleration due to gravity x height
i.e PE = m x g x h
1. At the top of the platform; mass = 65 kg, acceleration due to gravity = 10 m/, and height = 10 m.
Gravitational potential energy = 65 x 9.8 x 10
= 6370 Joules
The gravitational potential of the diver at the top of the platform is 6.37 KJ.
2. Halfway down; mass = 65 kg, acceleration due to gravity = 10 m/, and height = 5 m.
Gravitational potential energy = 65 x 9.8 x 5
= 3185 Joules
The gravitational potential energy of the diver halfway down is 3.185 KJ.
Answer: B) The identity of the solvent
Explanation:
Basically, the solvent is the liquid in which a solute is dissolved in. But the solute is the material to be dissolved.
Now in this case, the solute in the first solution is glucose and the solute in the second solution is an unidentified covalent solid material.
This means that:
• the identity of the solute cannot be identical in each solutions, which also means that the freezing points and densities of the solutions cannot be identical too.
• the only thing that is sure to be identical in the solution is the identity of the solvent.
