Answer:
The speed of molecule decreases and temperature also decreases
Explanation:
Kinetic energy of the molecules of a subsance is directly proportional to the temperature of molecule So as the kinetic energy decrease, temperature also decreases. decreses their speed.
All of the above. they would all decrease due to a lack of energy from using it in the beginning.
Answer:

Explanation:
We are asked to find the force applied to the volleyball. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

We are given the mass, but we must calculate the acceleration.
1. Acceleration
Acceleration is the rate of change of velocity with respect to change. It is the change in velocity over the time.

The volleyball starts at rest or 0 meters per second and reaches a velocity of 22 meters per second in 0.2 seconds.
= 22 m/s
= 0 m/s - t= 0.2 s
Substitute the values into the formula.

Solve the numerator.

Divide.

2. Force
Now we know the mass and acceleration, so we can calculate the force.

The mass is 0.5 kilograms and the acceleration is 110 meters per second squared.
Substitute the values into the formula.

Multiply.

1 kilogram meter per second squared is equal to 1 Newton, so our answer of 55 kg*m/s² is equal to 55 Newtons.

<u>55 Newtons</u> of force are applied to the volleyball.
Answer:Bohr placed the electrons in distinct energy levels. Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation: also rutherfords was just a hypothesis while Bhor took the time to make his an experiment
