Kinetic energy is the correct answer for this question
Answer:
# 5
Explanation:
The question describes silver being "poured" into a mold and cools to become a solid bar. This is the phase of liquid to solid. When a element cools down below it's freezing points to become a solid.
<u>Liquid to Solid Definition:</u>
Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.
C. The gravity on the Moon is less than the gravity on Earth.
Explanation:
The weight of Neil Armstrong changed because the gravity on the Moon is less than the gravity on earth. We can infer that the gravity on moon is one-sixth the gravity earth.
- Mass of Armstrong on earth and moon is the same. Mass is the quantity of matter contained in a substance. Since he has the same quantity of matter on earth and moon, his mass will be the same.
Weight is a function of mass and gravity on a body.
Since his weight reduced, we can infer that the gravity on the moon is lesser:
Weight = mass x gravity.

Answer:
C
Explanation:
i think he enjoyed the drums because it said he played in different bands
This is a redox reaction where oxidation and reduction take place. Here, Mg(s) oxidizes into Mg²⁺(aq) by increasing oxidation number from 0 to +2 while Ni²⁺(aq) reduces into Ni(s) by decreasing oxidation number from +2 to 0.
Oxidation
Mg(s) → Mg²⁺(aq) + 2 e
Reduction
Ni²⁺(aq) + 2 e → Ni(s)
Hence, 2.0 moles of electrons lost by Mg(s) when 2.0 moles of electrons are gained by Ni²⁺(aq).
