The force applied to raise a table to a height of 8m when 120 Joules of work is done is 15 N. That is, Force F = 15N
<h3>
What is Work ?</h3>
Work is the product of force and distance in the direction of force. Work is done on an object when the displacement of the object is in the direction of the force applied. That is,
W = F x S
The S.I unit of work is Joule.
Given that a table to a height of 8m and 120J of work was done. To find the force applies, the parameters to consider are
Make force F the subject of formula from the formula written above. That is,
F = W/S
F = 120 / 8
F = 15 N
Therefore, if the 120 Joule of work is done, the force applied to raise a table to a height of 8m is 15 Newtons.

It's C. increasing the masses of the objects and decreasing the distance between the objects
Answer:
p = 727.273 kg/m3, y = 7134.545 N/m^3, SG = 0.7273
Explanation:
Density is simply the amount of mass of a substance per unit of volume. It can be found by dividing the mass in kg by the volume im m^3:
Specific weight is the weight of the substance per unit of volume. The weight is the mass of the material times the gravity, and it represents the force that the earth exerts on an object. Another way of calculate this value, its multiplying the density of the fuel times the gravity. Then:
Specific Gravity is the ratio of the density of the substance to the density of a reference substance. For liquids, the reference substance is water at 4°C, which has a density of about 1000 kg/m^3.
Igneous rock makes up the majority of the mares. Because of volcanic eruption.
