Answer the following

1) A piece of gold weighis 240 g and has a volume of 20 cm^3. Find the density of gold.

2) What is the perpendicular distance between the force and the turning point if a force
of 25 N produces a moment of force of 12.5 Nm

Answer:

1. 12 g/cm³

2. 0.5 m

Explanation:

1.

The weight of the gold is 240 g

The volume is 20 cm³

Density = Mass/ volume

Density = 240 / 20 = 12 g/cm³

2.

The formula for moment of a force is ;

Force * distance perpendicular  between force and the turning point of force

Given that the moment of force is 12.5 Nm and force is 25 N  then the perpendicular distance between the force and the turning point will be;

12.5 = 25 * d

12.5/25 = d

0.5 = d

d= 0.5 m
