An important problem that all electric circuits have is the fact that since current is flowing through the traces connected the

components, the circuit is generating a complex magnetic field during operation. You can shield electric fields pretty easily using a Faraday cage, but how do you shield your device from the magnetic field it is generating itself

Answer:

grid or metal sheets or metal foams

Explanation:

Electric and magnetic fields are generated in electrical circuits that often cause interference in the measurements made.

To avoid these interferences, shields are generally used for the electric fields, Farday boxes are used, which are metal grids connected to earth.

For the magnetic field there is also a grid or metal sheets or metal foams,

It should be noted that the gaps in the screening must be smaller than the wavelength of the radiation to be screened.

A real heat engine operates between temperatures Tc and Th. During a certain time, an amount Qc of heat is released to the cold
Vlad [161]

Answer:

W_{max} =Q_C(\dfrac{T_H}{T_C} - 1)

Explanation:

given,

Temperature of heat engine operate between

Th (temperature in hot reservoir) and Tc(temperature in cold reservoir)

amount of heat released to = Qc

to find maximum amount of work = ?

now,

efficiency of heat engine

\eta = 1 - \dfrac{T_C}{T_H} = 1 -\dfrac{Q_C}{Q_H}

now,

\dfrac{T_C}{T_H} = \dfrac{Q_C}{Q_H}

Q_H= \dfrac{T_H}{T_C} Q_C

 maximum work =

W_{max} = Q_H - Q_C

W_{max} =\dfrac{T_H}{T_C} Q_C - Q_C

W_{max} =Q_C(\dfrac{T_H}{T_C} - 1)

above expression gives the expression of maximum amount of work.

Niagara Falls is a set of very large waterfalls located on the border between New York and Ontario, Canada. Over 200,000 cubic f
PSYCHO15rus [73]

Answer:

a) kinetic energy and gravitational potential energy

Explanation:

The water at the top of the fall possesses kinetic energy because the water is in motion, moving.

The water at the top also possess gravitational potential energy because it is falling under the influence of gravity. It is in a gravitational field.
