Question 1 1 pts Calculate the radiation (W) received by a collector with an area of...
Question 3 : Calculate the incidence angle of solar direct radiation at 1:00 PM LST on July 21st at latitude angle of 21.12o N & longitude angle of 39.45o E for a: - Surface facing South-West. - Horizontal surface
Question 1 0.5 pts The angle at which the Sun's rays strike the Earth's surface (the angle of incidence) varies by O decreasing with latitude O increasing with longitude o increasing with latidude O decreasing with longitude
Please show all work!!! Question 17 O pts 1) The surface area of the human body is about 1.8 m. If an average 37.0"C human is surfing in 10.0°C seawater in a 3.0 mm (1 milli- 10 thick neoprene wetsuit with a thermal conductivity of 0.050 W/(mK), how much heat does the surfer lose to the ocean in 1 hour? [1 hr = 3600 s) A lake has a specific heat of 4186J/kg.k). If we transferred 1.70x1094 J of heat...
Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
Please use the formulate sheet and show all steps to make sure the question is worth any points a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
