Question

Anwer Question 18 (5 points t the temperature ofl an object is multipled by 7,the amunt of power radated s multipled by what number? our Answer Question 19 15 poines h an experiment to that usedinour lab experimt0n_ with mm soaration between two bases) can pat be detected at a distance of 5.5 m. What is the approxiae angular resolution of this eye n Question 20 pe

Answer 1

Power alpha T^4, So if T = 7T, then P_new alpha 7^4 T^4 = 2401 T^4 Angular resolution = 10^-3/5.5 = 1.82 times 10^-4 radians = 0.182 mutilations 2.8 cm = (2.8 times 10) mm = 28 mm NOTE: a) If you find the solution doubtful or doesn't match with your answer provided, or you feel that I am wrong by any means feel free to mention that in comment.
