what is the capacitance of two square parallel plates 6.7 cm on a side that are separated by 1.8 mm of paraffin? the dielectric

almond37 [142]

The capacitance of two square parallel plates will be 1.777 farads.

<h3>What is the capacitance of two parallel plates?</h3>

The body's capacity to hold electric charge is constrained by capacitance. There is a capacitance for each capacitor. Two metallic sheets of area A, spaced by d, make up the standard parallel-plate capacitor.

The parallel plate capacitor formula is given by:

C = ε Ad

Two square parallel plates 6.7 cm on a side are separated by 1.8 mm of paraffin. The dielectric constant of paraffin is 2.2. Then the capacitance of two square parallel plates will be given as,

C = ε Ad

C = 2.2 x 0.67 x 0.67 x 1.8

C = 1.777 farad

Two parallel square plates will have a capacitance of 1.777 farads.

More about the capacitance of two parallel plates link is given below.

A pumpkin pie in a 9.00 in diameter plate is placed upon a rotating tray. Then, the tray is rotated such that the rim of the pie

Ghella [55]

Answer:

Explanation:

Given that,

Pie diameter = 9 in

Then, the circumference of the pie is

P = πd = 9π in

Then rim of the pie rotates 233 in,

Then,

1 Revolution of the pie is 9π in,

So, for 233 in, we will have

233 in / 9π in revolution

8.24 revolution

So, the revolution of the pie is 8.24

1 revolution is 2πrad

Then,

8.24 revolution = 8.24 × 2π = 51.78 rad.

And also, 1 revolution is 360°

Then,

8.24 revolution = 8.24 × 360 = 2966.4°

So,

In revolution, θ = 8.24 revolution

In radian = θ = 57.78 rad

In degree θ = 2966.4°

A basketball has a mass of 1 kg and is traveling 12 m/s

cricket20 [7]

A) It would be doubled.

Why?

To answer the question, we just need to calculate the momentum of the basketball using the following formula:

$Momentum=mass*velocity\\\\Momenum=1kg*12\frac{m}{s}=12\frac{kg.m}{s}$

Now, we have calculated the momentum and the result is 12 kg.m/s, what would happen to the velocity if we double the momentum? Let's calculate it!

$Momentum=mass*velocity\\\\(2)*12\frac{kg.m}{s}=1kg*velocity\\\\velocity=\frac{24\frac{kg.m}{s} }{1kg} =24\frac{s}{s}$

Hence, we can see that if the momentum is doubled, the velocity will be doubled too.

Have a nice day!
