I want right answer for both question. Little explanation also.please dont give wrong answer.
A distant star emits maximum intensity for wavelength 850 nm. What is its radiant intensity? 7.7 x 10 6W/m² 1.9 × 10 -4W/m2² 7.7 x 10 ³W/m² 1.9 x 10 4W/m² Next A current of 30 mA flows in a conducting wire on a z-axis towards positive direction and three cylindrical coaxial current sheets with diameters 5 cm, 3 cm and 2 cm carry current densities -60mA/m, -50mA/m and 40 mA respectively in the same direction. Calculate magnetic field intensity at diameter 4 cm. 1.76 nT 0.48 nT 1.62 nT 1.16 nT
