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.

Answer: C. Some of uranium's mass is converted into energy, so the smaller atoms have less mass.
Explanation:
From Einstein's mass-energy relation:
E = mc²
Mass and energy are equivalent. Mass can be converted into energy and energy into mass.
When Uranium atoms under go nuclear fission, smaller atoms are formed and huge amount of energy is released. This energy comes from the mass difference of the uranium nuclei and new nuclei formed. This mass converted into energy according to Einstein's equation.
Answer:
Explanation:
We can try writing the equation of the horizontal component of the length of the minute hand in terms of distance and the angle, that depends of time in this particular case.
The x-component of the length of the minute hand is:
(1)
- d is the length of the minute hand (d=D/2)
- D is the diameter of the clock
- t is the time (min)
Now, using the angular kinematic equations we can express the angle in term of angular velocity and time. As we know, the minute hand moves with a constant angular velocity, so we can use this equation:
(2)
Also we know, that the minute hand moves 90 degrees or π/2 rad in 15 min, so using the definition of angular velocity, we have:
Now, let's put this value on (2)
Finally the length x(t) of the shadow of the minute hand as a function of time t, will be:
I hope it helps you!
Answer:
The bottom of the cup passes the sound waves to the string, and so on to the other cup. You can hear surprisingly far using a string telephone if help the right way! If the string is kept tight, the sound waves will travel.
Explanation:
The mass of the object doesn't matter. The change in its momentum is equal to the impulse that changed it ... 15 N-sec.
