The rate of molecular motion will increase as the temperature rises. At the same temperature, an object with less massive molecules will have a faster molecular speed. Two objects with the same average kinetic energy will have the same temperature when kinetic temperature is applied.
1) A machine is an apparatus using or applying mechanical power and having several parts, each with a specific function.
2) Energy is the capacity of a physical system to do work.
3) Fuels are any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work.
4) Measure a volume of an acid and place into a polystyrene cup which is placed into a beaker.
Measure the temperature of the acid with a thermometer.
Add a measured volume of an alkali to the acid.
Measure the temperature rise to calculate the energy change.
5) the ratio of the useful work performed by a machine or in a process to the total energy expended or heat taken in; an action designed to achieve efficiency.
6) Pulley, lever, screw, and inclined plane.
Have a wonderful day ✨❤️

Answer: The force was 13.92 Newtons.
Explanation:
First, let's recall the second Newton's law:
The net force is equal to the mass times the acceleration, or:
F = m*a
where:
F = force
m = mass
a = acceleration.
When the player hits the ball with the bat, he applies a force that accelerates the ball for a small period of time, that increases greatly the speed of the ball.
In this case, we know that:
the mass of the ball is 0.145 kg
The acceleration of the ball is 96m/s^2
Then we can input those values in the above equation to find the force.
F = 0.145kg*96m/s^2 = 13.92 N
The force was 13.92 Newtons.
