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.
We are given the acceleration of the bus as a function of time:
a(t) = 1.2t
Let the velocity also be a function of time v(t).
Since a(t) is the change of v(t) over time, we can use the fundamental theorem of calculus to determine the velocity at t = 2s, or v(2), given that:
a(t) = 1.2t
v(1) = 5
v(2) - v(1) = 
v(2) - 5 = 
v(2) - 5 = 0.6t² evaluated between t = 1 and t = 2
v(2) - 5 = 0.6(4) - 0.6(1)
v(2) = 1.8 + 5
v(2) = 6.8m/s

A hydrometer is an instrument used to determine specific gravity
All atoms of the same element must have the same number if protons, however the number of neutrons can vary, giving different isotopes of the element.
