Calculate the density of Saturn. Show your work. How does it compare with the density of water? Explain how this can be.
stepladder [879]

Answer:

The density of Saturn is 686.81 kg/m³.

Explanation:

Mass of Saturn,  m=5.68\times 10^{26}\ kg  

Volume of Saturn, V=8.27\times 10^{23}\ m^3

Density of Saturn is given by its mass divided by its volume i.e.

d=\dfrac{m}{V}

d=\dfrac{5.68\times 10^{26}}{8.27\times 10^{23}}

d=686.81\ kg/m^3

So, the density of Saturn is 686.81 kg/m³.

The density of water is 1000 kg/m³. It is clear that the density of Saturn is less than water.

Let's practice calculating the frictional force of a skier on old "woody" skis and wet snow. The skier has a mass of 58 kg. The
kicyunya [14]

Answer:

Kinetic frictional force will be equal to 56.84 N

Explanation:

We have given mass of the skier m = 58 kg

Acceleration due to gravity g=9.8m/sec^2

Coefficient of kinetic friction \mu _k=0.1

We have to find the kinetic frictional force

Kinetic frictional force is given by

F_K=\mu _Kmg=0.1\times 58\times 9.8=56.84N

So kinetic frictional force will be equal to 56.84 N
