A book dropped from a certain height has no potential energy when it reaches the floor, since the height (a factor in the potential energy equation 'PE = mgh') becomes zero.
The potential energy of an object of mass (m) at height (h) is given by the formula PE = mgh, where g is the acceleration due to gravity (approximated as 9.8 m/s² on Earth). In this case, however, when a book reaches the floor after being dropped, its height is 0 meters, hence its potential energy is also 0 joules because potential energy is dependent on height.

They will accelerate the same
Neither will accelerate
Soccer ball will have greater acceleration. Therefore, the correct option is option B among all the given options.
Acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight forward is accelerated when it accelerates or decelerates. Even though the speed is constant, motion on a circle accelerates because the direction is always shifting. These tangential to the acceleration for all other motions.
Acceleration is a vector field since it has both a direction and a magnitude. A vector quantity is also velocity. The velocity vector change during a time interval multiplied by the interval of time is the definition of acceleration. Soccer ball will have greater acceleration.
Therefore, the correct option is option B.

Explanation:
3.01 x 1023 molecules of SO2
Answer:11.19 L of SO2
Explanation:use the dimensional analysis chart and you multiply 3.01 times 10^ 23 by 22.4 then take that answer and divide by 6.022 times 10^ 23
