Aluminium has the highest amount of specific heat, so the engineer should consider Aluminium to absorb the most heat generated by the motor.

Explanation:

The capacity of heat absorbed by any metal can be calculated using the formulation of product of its specific heat with the mass and change in temperature.

Heat absorbed = Specific heat * Mass*change in temperature

So as the absorption capacity of any metal is directly proportional to the specific heat of the metal. The more the specific heat of the metal, the more amount of heat it can absorb. As specific heat is the amount of heat energy required to raise the temperature of an object by 1°C. So the greater the specific heat, the greater amount of heat energy will be absorbed by that metal.

Among the given options, aluminium has the highest amount of specific heat, so the engineer should consider Aluminium to absorb the most heat generated by the motor.

n electromagnetic wave in vacuum has an electric field amplitude of 611 V/m. Calculate the amplitude of the corresponding magnet
enot [183]

Answer:

The  corresponding  magnetic field is  

Explanation:

From the question we are told that

    The electric field amplitude is  E_o   =  611\  V/m

   

Generally the  magnetic  field amplitude is  mathematically represented as

              B_o  =  \frac{E_o }{c }

Where c is the speed of light with a constant value

         c = 3.0 *0^{8} \ m/s

So  

        B_o   =  \frac{611 }{3.0*10^{8}}

         B_o   =  2.0 4 *10^{-6} \  Vm^{-2} s

Since 1  T  is  equivalent to  V  m^{-2} \cdot  s

         B_o  =  2.0 4 *10^{-6} \ T

The magnetic flux through a loop:
dexar [7]

Answer:

The magnetic flux through a loop is zero when the B field is perpendicular to the plane of the loop.

Explanation:

Magnetic flux are also known as the magnetic line of force surrounding a bar magnetic in a magnetic field.

It is expressed mathematically as

Φ = B A cos(θ) where

Φ is the magnetic flux

B is the magnetic field strength

A is the area

θ is the angle that the magnetic field make with the plane of the loop

If B is acting perpendicular to the plane of the loop, this means that θ = 90°

Magnetic flux Φ = BA cos90°

Since cos90° = 0

Φ = BA ×0

Φ = 0

This shows that the magnetic flux is zero when the magnetic field strength B is perpendicular to the plane of the loop.

Why did the “yielders” conform in Asch’s experiment?
svet-max [94.6K]

Answer:

Asch's experiment showed that about 75% of people were "yielders" who conformed and 25% were "independent" who didn't conform. Asch concludes that people ignored reality and gave an incorrect answer in order to follow the rest of the group.
