Answer:
Also as we can see the equation that heat flux directly depends on the temperature gradient so more is the temperature gradient then more will be the heat flux.
For positive temperature gradient the heat will flow outwards while for negative temperature gradient the heat will flow inwards
Explanation:
As we know that heat flux is given by the formula
here we know that
K = thermal conductivity
= temperature gradient
now we know that
also we know that
K = 1.7 W/mK
now we have
so temperature gradient is given as
also in other unit it will be same

Answer:
Explanation:
Magnetic field due to moving charge =
q is charge moving with velocity v and r is distance from point at which field is calculated .
For alpha particle
= 0.1316 x 10⁻³ T
For electron
= .0658 x 10⁻³ T .
Both these magnetic field will be same in direction because direction of equivalent current is same for both the particles .
Hence
Total magnetic field
= B₁ + B₂ = .1974 x 10⁻³
= 1.974 x 10⁻⁴ T .
