Density of a regular solid – Lead

 

Mass = 175.4g

Width = 2cm

Length = 5cm

Height = 4.6cm

Volume = width x length x height

V = 2 x 5 x 4.6 = 46cm3

P = m / V = 175.4 / 46 = 12.5g/cm3

·         4.14 describe power as the rate of transfer of energy or the rate of doing work

"Rate" just means "divided by time" (see Entrance Activity)

 

So

 

Power = Energy / Time

 

or

 

Power = Work done / Time
