The density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.
<h3>What is the relationship between acceleration and density?</h3>
For a solid falling through a viscous fluid, the acceleration of the object decreases until it attains terminal velocity.
The acceleration of the body increases with increase in density of the solid.
When density of solid = density of liquid, acceleration a = g
When density of solid = 2 × density of the liquid, acceleration a = g/2.
Therefore, the density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.

Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.

Answer:
(a) the work done by the student is 110.1 J
(b) The gravitational force that acts on the amplifier is 102.9 N
Explanation:
Given;
mass of the amplifier, m = 10.5 kg
initial position of the amplifier, x₀ = 1.82 m
final position of the amplifier, x₁ =0.75 m
The dispalcement of the amplifier Δx = x₁ - x₀ = 1.82 m - 0.75 m = 1.07 m
(b) The gravitational force that acts on the amplifier;
F = mg
F = 10.5 x 9.8
F = 102.9 N
(a) the work done by the student is calculated as;
W = FΔx
W = 102.9 x 1.07
W = 110.1 J
