Ice has a density of 0.920 g/cm3. An ice cubes mass is 100 g. What is its volume?
Tasya [4]

Answer:

\boxed {\tt 108.695652 \ cm^3}

Explanation:

Volume can be found by dividing the mass by the density.

v=\frac{m}{d}

The mass is 100 grams and density is 0.920 grams per cubic centimeters.

Therefore,

m=100 \ g \\d= 0.920 \ g/cm^3

Substitute the values into the formula.

v=\frac{100 \ g}{0.920 \ g/cm^3}

Divide. Note that the grams, or "g" will cancel each other out.

v- 108.695652 \ cm^3

The volume of the ice cube is 108.697652 cubic centimeters.

the gasoline in a car does 40000 j of work on a car and generates a constant force of 20 n. how far did the car go?
NikAS [45]

     Work  =  (force) x (distance)

     40,000 J  =  (20 N) x (distance)

     Distance  =  (40,000 J) / (20 N)

                    =    2,000 meters

                    =     2 kilometers.

(20 N is not a huge force when it's being used to move a car.
It's only about  4.5 pounds.)
