Explanation 1) Concept: We equate the intensity of receiver and intensity of earth to find the power of the receiver. In the second case, we equate the intensity of source to the intensity of earth to find the power of the source. 2) Formula: P = I A 3) Given: i) Antenna diameter D A = 300 m ii) Distance of galactic center from source R s = 2.2 × 10 4 l y 4) Calculations: a) Power received by the Arecibo antenna : The intensity of the signal on the surface of the earth and the intensity of the signal received by the antenna has to be the same. I E = I A The intensity is nothing but power per unit area. I = P A P E A E = P A A A A E = s u r f a c e a r e a o f e a r t h = 4 π R E 2 , A A ( a r e a o f a n t e n n a ) = π R A 2 P E A E = P A A A P A = A A A E P E P A is the power radiated by the antenna. P A = R A 2 4 R E 2 P E = 1 × 10 - 12 W 4 R A 2 R E 2 P A = 1 × 10 - 12 W 4 300 m 2 4 6.37 × 10 6 m 2 P A = 1.4 × 10 - 22 W b) Power of the source at the center of our galaxy: The intensity of the source is equal to the intesity on earth: I E = I s The intensity is nothing but power per unit area

You are working with a team that is designing a new roller coaster-type amusement park ride for a major theme park. You are present for the testing of the ride, in which an empty 150 kg car is sent along the entire ride. Near the end of the ride, the car is at near rest at the top of a 100 m tall track. It then enters a final section, rolling down an undulating hill to ground level. The total length of track for this final section from the top to the ground is 250 m. For the first 230 m, a constant friction force of 370 N acts from computer-controlled brakes. For the last 20 m, which is horizontal at ground level, the computer increases the friction force to a value required for the speed to be reduced to zero just as the car arrives at the point on the track at which the passengers exit. (a) Determine the required constant friction force (in N) for the last 20 m for the empty test car. Write AK + AU + AE int = W+Q + TMW + TMT + TET + TER for the car-track-Earth system and solve for…
