Answer:

E=0.5 m v^2

2*10^-5 = 0.5 1000*v^2

4*10^-5=1000v^2

4*10^-8=v^2

2*10^-4 =v

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.

What is free fall? Explain it in brief.

xxTIMURxx [149]

· free fall is any motion of a body where gravity is the only forceacting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
