If you flow from a warmer object to a cooler object until they are both the same temp then you are heat. because heat flows from warm to cool until it reaches thermal equilibrium (when they are the same temp)

Suppose that a rectangular toroid has 2,000 windings and a self-inductance of 0.060 H. If the height of the rectangular toroid i

andrey2020 [161]

Answer:

0.01154 A

Explanation:

We have given the energy in the magnetic field $U=4\times 10^{-6}J$

Value of inductance L =0.060 H

Energy stored in magnetic field is given by $U=\frac{1}{2}Li^2$

$i=\sqrt{\frac{2U}{L}}$

$i=\sqrt{\frac{2\times 4\times 10^{-6}}{0.06}}=0.01154\ A$

So the current flowing through rectangular toroid will be 0.01154 A

A clothing manufacturer uses lasers to cut patterns in fabric when making T-shirts. Which best describes a benefit of using lase

Semenov [28]

I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.

Which landform is produced at location E where the Mississippi River enters the Gulf of

mixer [17]

Answer:

a delta

Explanation:

The landform produced at the location E where the Mississippi River enters the Gulf of Mexico is a delta.

A delta is a depositional landform where a smaller body of water enters into a larger one.

The Gulf of Mexico contains a larger body of water and as the Mississippi river enters into it, it splits up into many distributaries.

So, this feature is a delta.

The charge on the square plates of a parallel-plate capacitor is Q. The potential across the plates is maintained with constant

uysha [10]

Answer:

The amount of charge on the plates is now equal to half its original value

Explanation:

From the question we are told that

The charge on the plate is Q

The initial separation is $d_1$

The new separation is $d_2 = 2 d_1$

Generally the capacitance of the capacitor is mathematically represented as

$C = \frac{\epsilon * A }{d}$

Generally the charge of the parallel plate capacitor is mathematically represented as

$Q =CV$

=> $Q =\frac{\epsilon * A * V }{ d}$

Here $\epsilon$ , A and V are constant , so looking at the question we see that Q varies inversely with d

$Q = \frac{K}{d}$

Here K is a constant

$Qd = K$

=> $Q_1 d_1 = Q_2 * d_2$

=> $Q_1 d_1 = Q_2 * [2 d_1]$

=> $Q_2 = \frac{Q_1}{2}$

So we see from the mathematically relation that the charge of the parallel plate capacitor will reduce by half of it original value

How does a change in medium affect light?

Ymorist [56]

<span>The speed of light changes as it passes from one medium to another medium due to the difference in the density of the two media. This is the reason for refraction of light also.</span>
