Problem Filamentary currents of -25a, and 25a, A are located in the r=0 plane in free space at y =-1 and y = Im respectively. A third filamentary current of 10 a, A is located at r= k, y = 0. Finnd the vector force on a l-m length of the 1-mA filament and plot |F| versns k: The total B field arising from the two 25A filaments evaluated at the location of the 1-mA filament is, in cartesian Components?​

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
