Given the following Landsat measured reflectance for R, G, B, NIR, and thermal infrared intensity (TIR), for a pixel, determine if it is likely to be conifer forest, hardwood forest or desert/urban? (various temperatures and NDVI values). Explain how you know. Reflectances and spectral radiance: blue (0.4 um) = 0.11; green (0.5 um) = 0.14; red (0.7 um) = 0.07 NIR (1.1 um) = 0.3; TIR (10.3 um) = 5.3 W/m2/um/ste

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?

Two 2.0-cm-diameter disks face each other, 1.0 mm apart. they are charged to ±10 nc. what is the electric field strength between the disks? a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
