Answer:

GPE = 199.92 Joules

Work = 199.92 Joules

Explanation:

A 5.1 kg beer cub weighs 49.98N

Mg = F

g = F/M

g = 49.98/5.1

g = 9.8 m/s²

GPE = mgh

GPE = 5.1 * 9.8 * 4

GPE = 199.92 Joules

The work done by the mother is equal to the GPE , because

Force*distance = work

Force = 49.98N

Distance = 4m

Work = 199.92 Joules

The volume of a piece of metal of a mass 6 gram is 15cm3. What is the density of the metal piece?
torisob [31]

Answer:

0.4 g/cm^3

Explanation:

The density of an object can be found using the following formula.

d= m/v

where m is the mass and v is the volume.

The mass of the metal is 6 grams and the volume is 15 centimeters^3

m=6 g

v= 15 cm^3

Substitute these into the formula.

d= 6 g/ 15 cm^3

Divide 6 g by 15 cm^3 (6/15=0.4)

d= 0.4 g/ cm^3

The density of the metal is 0.4 grams per cubic centimeter.
