How do nuclear power plants work?

As already stated, to get a nuclear plant up and running requires first of all enriched uranium. To give you an idea, 0.5kg of enriched U-235 - the amount used to power submarines and nuclear aircraft carriers - is equivalent to 3.8 million liters of gasoline.

Centripetal force

When a body performs a Circular Motion, it undergoes an acceleration that is responsible for changing the direction of movement, which we call centripetal acceleration, as seen in the MCU. Knowing that there is an acceleration and given the mass of the body, we can, by Newton's 2nd Law, calculate a force that, like the centripetal acceleration, points to the center of the circular path.

Gas Study Exercises

3. A gas cylinder cannot vary the volume of gas inside. If it is taken from an airy environment where the internal pressure is 3 atm and the temperature 15 ° C and is placed under the sun where the temperature is 35 ° C. Assuming the gas is ideal, what will be the pressure after transformation?
