<h2>If the object is moving then it has kinetic energy</h2>
Answer:
Explanation:
We're starting a car. We have the fuel in the engine, and when the engine starts, that fuel is converted into power to move the car. The fuel is made of chemicals, right? Propane, gasoline, so on. What kind of energy comes from chemicals? <em>Chemical energy</em>, right?
That fuel is <em>chemical energy</em>, and the energy to move the car must be <em>kinetic/mechanical</em> energy. However, that's not the <em>only</em> source of <em>mechanical energy</em>.
There's another source of <em>mechanical energy</em> here as well: we have an electric battery. What kind of energy is found in a battery? The battery has electricity, and so it has <em>electrical energy</em>. Some of that <em>electrical energy</em> turns into <em>mechanical energy</em> when the car starts up.
But the engine heats up as well, right? There's one more energy that the <em>electrical energy</em> and <em>chemical energy</em> produce here: <em>thermal energy</em>. That's the source of the heat.
I hope this makes sense for you. Have a wonderful day!
In a limited government, the power of government to intervene in the exercise of civil liberties is restricted by law, usually in a written constitution. It is a principle of classical liberalism, free market libertarianism, and some tendencies of liberalism and conservatism in the United States
Answer:
The time is 16 min.
Explanation:
Given that,
Time = 120 sec
We need to calculate the moment of inertia
Using formula of moment of inertia
If the disk had twice the radius and twice the mass
The new moment of inertia
We know,
The torque is
We need to calculate the initial rotation acceleration
Using formula of acceleration
Put the value in to the formula
We need to calculate the new rotation acceleration
Using formula of acceleration
Put the value in to the formula
Rotation speed is same.
We need to calculate the time
Using formula angular velocity
Put the value into the formula
Hence, The time is 16 min.
