Answer:
<h2>
1 kg</h2>
Explanation:
Check the diagram attached below for the diagram.
Let the weight of the rock be W and the mass of the meter stick be M. Note that the mass of the meter stick will be placed at the middle of the meter stick i.e at the 50cm mark
Using the principle of moment to calculate the weight of the rock. It states that the sum of clockwise moments is equal to the sum of anti clockwise moment.
Moment = Force * perpendicular distance
The meterstick acts in the clockwise direction while the rock acys in the anti clockwise direction
Clockwise moment = 1kg * 25 = 25kg/cm
Anticlockwise moment = W * 25cm = 25W kg/cm
Equating both moments of forces
25W = 25
W = 25/23
W = 1 kg
The mass of the rock is also 1 kg
When discharging equivalent of 0% starting voltage will the capacitor reach after 5RC.
V(t) = V0e-t/RC = V0b initially.
<h3>What is capacitor?</h3>
- In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.
- Capacitance refers to a capacitor's effect.
- The terminals in a capacitor are connected to two metal plates that are spaced apart by a dielectric, a non-conducting material.
- Two pieces of aluminum foil, along with a piece of paper, can be used to create a capacitor (and some electrical clips).
- It won't have a lot of storage capacity, so it won't be a great capacitor, but it will still function.
<h3>What are the different types of capacitors?</h3>
The numerous kinds of capacitors and their applications.
- Frequently utilized in radio tuning circuits is air.
- Mylar: The material most frequently used in timer circuits for clocks, alarms, and counting.
- Good for high-voltage applications is glass.
- Ceramic is used in X-ray, MRI, and other high-frequency devices.
- a powerful capacitor fuels hybrid and electric vehicles.
