The volume of a 155-gram sample of mercury is 11.397 mL if the density of mercury is 13.6 g/mL.
It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.
It is given that:
The density of mercury is 13.6 g/mL.
The mass of the mercury is 155 grams.
As we know,
Volume can be defined as a three-dimensional space enclosed by an object or thing.
The density = mass/volume
13.6 = 155/volume
volume = 155/13.6
volume = 11.397 mL
Thus, the volume of a 155-gram sample of mercury is 11.397 mL if the density of mercury is 13.6 g/mL.

Answer:
the work done on the car by the applied force is 75 J.
Explanation:
Given;
initial velocity of the car, v = 4 m/s
applied force in opposite direction, F = 5N
initial position of the car, x₀ = 5 m
final position of the car, x₁ = 20 m
displacement of the car, Δx = x₁ - x₀ = 20 m - 5m
= 15 m
The work done on the car by the applied force is calculated as follows;
W = F.Δx
W = 5 x 15
W = 75 J
Therefore, the work done on the car by the applied force is 75 J.
