When discharging, what percentage of the starting voltage will the capacitor reach after 5rc?
Ahat [919]

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.

Stairway must have uniform riser height and tread depth; variations in riser height or tread depth shall not be over _______ inc
alexandr1967 [171]

Answer:

\frac{3}{8} inches

Explanation:

the variations in riser height or tread depth should not be grater than \frac{3}{8} inches that is equal to 9.5 mm but the maximum riser height should be the  \frac{81}{4} inch  but variation in riser height should not exceed to \frac{3}{8} inches. The minimum riser height should be 7 inches which is equal to the 178 mm

If two objects A and B have the same kinetic energy but A has three times the momentum of B, what is the ratio of their inertias
Thepotemich [5.8K]

Answer:

\frac{inertia_B}{inertia_A}=9

Explanation:

First of all, let's remind that:

- The kinetic energy of an object is given by K=\frac{1}{2}mv^2, where m is the mass and v is the speed

- The momentum of an object is given by p=mv

- The inertia of an object is proportional to its mass, so we can write I=km, where k just indicates a constant of proportionality

In this problem, we have:

- K_A = K_B (the two objects have same kinetic energy)

- p_A = 3 p_B (A has three times the momentum of B)

Re-writing both equation we have:

\frac{1}{2}m_A v_A^2 = \frac{1}{2}m_B v_B^2\\m_A v_A = 3 m_B v_B

If we divide first equation by second one we get

v_A = 3 v_B

And if we substitute it into the first equation we get

m_A (3 v_B)^2 = m_B v_B^2\\9 m_A v_B^2 = m_B v_B^2\\m_B = 9 m_A

So, B has 9 times more mass than A, and so B has 9 times more inertia than A, and their ratio is:

\frac{I_B}{I_A}=\frac{km_B}{km_A}=\frac{9m_A}{m_A}=9
