The main observation that suggests that it is a mixture of substances is that fact that it produces a gas which facilitates the rising of the baked goods.
It should be noted that the angular momentum remain constant and kinetic energy of the skater increases.
<h3>What is Angular momentum?</h3>
Angular momentum can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then angular momentum is constant.
Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.

The volume of the rectangular pyramid is 28 cubic feet.
<h3>
How to find the volume of the pyramid?</h3>
The volume of a pyramid of base B and height H is given by:
Here we know that the height is H = 7ft, and the base is a rectangle of 4ft by 3ft, so the area of the base is:
Then the volume of the pyramid is:
