For a two-cover FPC of dimensions 3 x 6 m, tilted 45 degrees from horizontal, determine the overall
heat loss coefficient. The environmental temperature is 5 C and the wind blows at 5 m/s.
The absorber plate is 0.6 mm thick with an emissivity of 0.15. The glass covers are 3.5 mm
thick with a gap of 20 mm and the bottom one is located 50 mm from the absorbing plate.
The glass emissivity is 0.88. The insulation is fiberglass 50 mm thick at the back and
30 mm at the edges. The mean absorber temperature is 90 C. Estimate the overall heat loss
coefficient using both the detailed and the empirical methods and compare the results

if a galaxy is tilted 45 degrees to my line of sight then how much does the wavelength of 21 cm shift when you move from the center to the edge of galaxy given a orbital speed of 220 km/s?

A) Block 1 (5 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal.

Please ANSWER ALL parts of the question. Thanks A) Block 1 (5 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 65 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.2. Assume that the x-axis is parallel to the incline and positive in the direction...

I need to find the trajectory of a projectile launched at 1000 m/s at 45 degrees to the horizontal, launched in an easterly direction from a point on the equator. I have to assume that it is a lead sphere of radius r = 5cm. Also, what is the distance of the landing point from the launch point? Including the effects of the coriolis force and the effects of linear and quadratic air resistance. What would this trajectory look like?...
