Find the density of a substance that has a volume of 754 cm3 and a mass of 7,917 grams. Don't forget your units!

Anit [1.1K]

Answer:

$\boxed{\sf Density \ of \ the \ substance = 10.5 \ g/cm^3}$

Given:

Mass (M) = 7917 grams

Volume (V)= 754 cm³

To Find:

Density of the substance

Explanation:

$\boxed{ \bold{\sf Density \ (\rho) = \frac{Mass \: (M)}{Volume \: (V)}}}$

Substituting values of M & V in the equation:

$\sf \implies \rho = \frac{7917}{754}$

$\sf \implies \rho = 10.5 \: g/ {cm}^{3}$

What is the power involved in lifting a 1.0-kg object 1.0 m in 1.0 s??

MAVERICK [17]

Mass = 1kg
Distance = 1m
Time = 1s
Force= Mass x Acceleration due to graviy
          = 1 x 9.8 = 9.8
Velocity = Distance / time
              = 1 / 1 =1m/s
Power = Force x velocity
           = 9.8 x 1 = 9.8 W
