Question

By about what percentage will the edge length of an ice cube decrease if the cube loses 7% of its volume by melting?

Answer #1

Suppose initial edge length is **x**

**So volume =
**

**New volume is 7% less than the actual volume ()
Means new volume is (100-7)% of
**

**New volume =
**

**New edge length =
**

**Or,
**

**Decrement in edge length = x -0.9761x =
0.0239x**

**% decrease in length =
**

**Answer is 2.39%**

You have a large cube with an edge length of 4 m and a density
of 6.6 kg/m3. Calculate the volume of the cube.

There is a cube of length c. It is in unstable equilibrium,
balanced on its edge. The cube is at rest on frictionless surface
A. A small shock, or impulse, causes the cube to escape the
equilibrium point and topple. After the cube is toppled, the cube
is under uniform gravitational field, meaning that g is constant.
The cube rotates until any part of it hits the table. Before the
cube hits the table, what is the cube's final angular...
