Tell me what the laws of thermodynamics are in a simple way​

Physics
1 answer:
MaRussiya [10]3 years ago
8 0

Answer:

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.  The second law of thermodynamics states that the entropy of any isolated system always increases.  The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

As the frequency of the ac voltage across a capacitor approaches zero, the capacitive reactance of that capacitor:___________.
sergij07 [2.7K]

Answer:

B) approaches infinity

Explanation:

The capacitive reactance of an AC capacitor is given by;

X_C = \frac{1}{\omega C } = \frac{1}{2\pi f C}

Where;

C is the capacitance

f is the frequency of the ac voltage

X_C = \frac{1}{\omega C} = \frac{1}{2\pi f C} \\\\X_C = \frac{1}{2\pi f C} \\\\X_C = \frac{1}{2\pi (0) C} \\\\X_C = \frac{1}{0} \\\\X_C = \ infinity

Therefore, as the frequency of the ac voltage across a capacitor approaches zero, the capacitive reactance of that capacitor approaches infinity.

The correct option is (B) approaches infinity

What are the two main types of energy?
djyliett [7]

Answer:

Fourth option

Explanation:

They're many different types of energy, from chemical and mechanical to heat and solar energy. But the two most basic types of energy are "kinetic and potential energy" or the fourth option. Kinetic energy is the energy an object has when it is in motion, while potential energy is the energy an object has when it's as rest. These two specific types of energies are the most basic and you can even convert them into many different types of energies, like heat or electrical energy.

Hope this helps.
