Answer:
The automobile tire rotates 91 revolutions
Explanation:
Given;
angular acceleration of the automobile, α = 2.13 rad/s²
time interval, t = 23.2-s
To calculate the number of revolutions, we apply the first kinematic equation;
the initial angular velocity is zero,
Find how many revolutions that are in 573.2256 Rad
Therefore, the automobile tire rotates 91 revolutions
Answer:
Consistency paradox is the observation that a human being’s personality tends to remain the same over time, while their behavior can change in different situations.
Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.

Answer:
1) True: Spring A is stiffer than B (kA > kB). Less work must be expended on spring A if both springs are stretched by the same amount.
2) False: The kinetic energy of an object depends on the direction of the motion involved.
3) True: The work done to raise a box onto a platform does not depend on how fast it is raised.
4) True: The friction force is a non-conservative force.
5) True: The kinetic energy can be negative.
6) False: The kinetic energy does not depend on the reference frame of the observer.
7) False: Work can be done in the absence of motion.
8) False: If the moon revolves around the earth in a perfectly circular orbit, then the earth does do work on the moon.
Mechanical advantage is a force which is measure of a force amplifying effectiveness of a simple machine.so t<span>he number of times a machine multiplies the effort force is mechanical advantage .
