friction is the force that resists the sliding or rolling of an object over another.
Answer: Approximately 15,192 kilometers
Answer:
Due to the rotating effect created due to opposite acting offset forces of the body weight and the normal reaction from the heels.
Explanation:
- We cannot stand on heels with a wall at the back support and then bend over to touch the toes and regain the position back by standing up because we have the center of mass of our body somewhere at the abdominal portion of our body.
- So, while standing on our heels we are giving our body only one point to support and balance itself.
- On bending the center of mass of our body shifts forward and it is now not vertically in line to the direction of the support reaction from the heels because of the wall at the back we cannot bend our knees and move our weight over our heels for gaining the balance. Due to a difference between the these two opposite forces we have a turning effect called moment on the center of mass of our body. This tries to rotate our body in the forward direction about the center of mass of our body.

Explanation:
As we presume that the fluid density is greater than the gas density based on common sense, the volume of the balloon decreases. The mass per unit volume is known as fluid density.
Greek letter stands in for and (rho). Mass per length squared, or M/L3, is the unit of measurement for density. Specific Weight vs. Weight Density: A fluid density, also known as specific density, is determined by dividing the fluid's weight by its volume. Weight per volume of a fluid is also referred to as weight density.
A mathematical term called "volume" describes how much three-dimensional space is occupied by an item or a closed surface. The measurement of volume is done in cubic units, like m3, cm3, in3, etc.
