Answer:

Lenz Law

Explanation:

As per Lenz's law we know that direction of induced current is such that the magnetic field resulting from the induced current opposes the change in the field that caused the induced current.

This law is based upon the energy conservation principle as when magnetic field linked with the closed conducting loop changes then the work done to change the magnetic flux is used to induced the current and electrical energy in the closed loop.

As we know that when magnetic flux linked with the closed loop increases then the induced current in the loop will try to decrease the magnetic flux in such a way that its induced current will induce its magnetic field in opposite direction. And similarly if the flux linked with the closed loop decreases then induced current will increase the flux by inducing the magnetic field in the same direction

Calculate the change in length of a Pyrex glass dish (Coefficient of linear expansion for Pyrex is 3 x 10^-6 /C) that is 0.3 met
Readme [11.4K]

Answer:

0.000225 m

Explanation:

Coefficient of linear expansion = \alpha_L=3\times 10^{-6} /C

Length = 0.3 meters

ΔT = Change in temperature = 250 °C

Linear expansion

\frac{\Delta L}{L} = \alpha_L\Delta T\\\Rightarrow \Delta L=\alpha_L\Delta T\times L\\\Rightarrow \Delta L=3\times 10^{-6}\times 0.3\times 250=0.000225\ m

Change in length of the Pyrex glass dish is 0.000225 m.

Answer:

Super-critical mass

Explanation:

This term refers to the mass, in which the amount of fission processes per unit of time increases to the point, where some intrinsic feedback mechanism causes the reactor to reach an equilibrium point at a high temperature or power, that is, It becomes critical again, or it is destroyed due to the amount of processes.

<em>1) The relationship in between the electrical energy carriesd by the transmission wires and the amount of the heat loss in it is due to the reason that when the electricity is flown through the wires there are some resistance found in these wires which creates a disturbance in the efficient flow of electricty.Also we know that current have an heating effect when it is in motion as due to if a large amount or magnitude of electricity is flown through the transmission wires it will carry a larger heat effected and also due to the resistance is provided by the wires and so the process of heat loss takes place.</em>

<em>2)It is important to minimize current in transmission wires due to minimize the heat loss and resistance on flowing electric current to make the system more efficient </em>
