A microwave is equipped with two sources of microwave light that emit at a frequency of = 18.8 GHz. The two sources are housed in an air-filled chamber as shown below. The f spacing between the sources is d = wall is x, = 17.5 cm. The dimensions of the chamber are height y = x = 84.0 cm. 5.00 cm. The distance from the left source to the left 50.0 cm and width

A solar cooker has a rectangular light collection area of 80 cm X 125 cm. If sunlight of intensity 1.2 kW/m² is incident on its surface at an angle of 60 degrees with respect to the normal, calculate the power collected by the solar cooker. O 0.4 kW 0 1 kW O 1.2 kW O 0.6 kW

A circular loop of wire can be used as a radio antenna. If an 19.8-cm-diameter antenna is located 3.00 km from a 88.9 MHz source with a total power of 60.1 kW, what is the maximum emf induced in the loop? The orientation of the antenna loop and the polarization of the wave are as shown in (Figure 1). Assume that the source radiates uniformly in all directions. Figure In vicinity of loop, wave propagates in +x-direction. In vicinity of loop. E has only a y-component and B has only a 2-component. E B 1 of 1 > Circular loop antenna lies in xy-plane. ▼ Answer Requested Part G Determine the time-dependent induced emf in the loop.

An isotropic point source emits light at wavelength 470 nm, at the rate of 210 W. A light detector is positioned 450 m from the source. What is the maximum rate dB/dt at which the magnetic component of the light changes with time at the detector's location? The speed of light is c = 3 x 108 m/s, and Ho = 47 x 107 H/m. Number 2.98754 UnitsTT/s the tolerance is +/-5%
