Answer:

Explanation:

κ = 1/v  x dv/dp

= 1/ρ x (+δρ/ δp )_T

δρ = 1 , ρ = 100

44.18 x 10⁻⁶ = ( 1/100) x( 1 / δp)

δp = 10⁻² / (44.18 x 10⁻⁶ )

= .0226 x 10⁴

= 226 bar

The relationship between body mass body weight and body density
nordsb [41]

Answer:

The formula for calculating Density is:

= Mass / Volume

From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.

If mass however was decreasing, density would have to decrease as well.

For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.

Density of 5kg brick = 5 / 5 = 1 kg/m³

Density of 10kg brick = 10 / 5 = 2kg / m³

Density of 15kg brick = 15 / 5 = 3 kg /m³

<em>Notice how density increases as mass increases and decreases when mass decreases. </em>

A 75kg man goes up a tower 30 m in 120s. How much power did the man exert
Pepsi [2]

Explanation:

If g= 10m/s²

Then 75kg=75×10=750N

Since Work =Force ×Distance

Work=750×30

=22500J

And Power°=Work÷time

=22500÷120

=187.5W
