Answer:
<u><em>Rate of dissolving compounds:</em></u>
If we increase the temperature of the solution, then the dissolving compound would dissolve more easily.
<u><em>Boiling Point of Compounds:</em></u>
If the inter-molecular forces of any compound is really strong, then the boiling point of the compound would be really high.
The gravitational pull is weaker.
The force of gravity on earth is 9.807 m/s^2 (or meters per second per second).
To determine the force applied, multiply the mass of the package (5.7 kg) by the force of gravity on Earth (9.807 m/s^2).
5.7 x 9.807 = 55.86 N The answer is D.
Note: the actual force is 55.89 Newtons.
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
The pitch of a sound is most closely related to the frequency of vibrations.
