Answer:
The current increases.
Explanation:
A capacitor can be defined as an electronic component used in electrical circuits to store charge temporarily.
A capacitor is connected to an AC generator. As the generator's frequency is increased, the current in the capacitor increases as well.
This ultimately implies that, when a capacitor is connected to an AC generator, the frequency of the circuit is directly proportional to the amount of current flowing through it.
Answer: A
Explanation:
Molecules speed up as heat is added
For example when water is heated as the water gets hotter the molecules speed up causing the water to boil and change phases into a gas (this is called evaporation)
In an ice cube the water molecules are frozen (barely moving compressed tight together) as the ice cube heats up the molecules start speeding up and moving further apart as the ice cube turns into liquid form. So as heat is added molecules speed up, move faster and spread further apart
Answer:
The distance by which the spring stretches is 1.48 cm.
Explanation:
Given that,
An object on a vertical spring oscillates up and down in simple harmonic motion with an angular frequency of 25.7 rad/s, 
We know that angular frequency in SHM is given by :
When the object is allowed to hang stationary from it, the force due to spring is balanced by its weight. Such that :
From equation (1) :
So, the distance by which the spring stretches is 1.48 cm.
You use less energy to provide the same service.
