- The Sun as seen from Earth has an apparent magnitude of -26 in the B-band.1. What would its apparent magnitude be as seen from Jupiter? (Jupiter is approximately 5.2 AU from theSun.)2. At a certain distance d from a Star A, its apparent brightness is f. If we were to travel at a relativisticvelocity to a point in space which is 5 times further away, how much fainter would the star appear to us?(i.e. what fraction of its original apparent brightness would it now appear to us?)Radial wave functions. Explain briefly?we have this problem in our class today that left me puzzled. here it is Lets say i have a rod. and this rod has a length of 50 cm lol. lets say this rod has a nonuniform density. 2=A+BVx lets say lambda is measured in g (gram) per m (meter) and x would be measured in m. A = 50 g/m B = 25 g/m^3/2 %3D FIND: a. need to find the dm for this one shape b. get the mass of our rod c. get the centre of mass of our rod

You plan to build yourown telescope that can resolve the Great Red Spot on the surface of Jupiter at a wavelength of600 nm. The farthest distance between the Earth and Jupiter is 968 × 106 km and the Great RedSpot has currently a diameter of 16,500 km.(a) Use the Rayleigh criterion to determine the diameter of the lens’ aperture of your telescopethat is needed to resolve the Great Red Spot on Jupiter.[6/2, 7:44 AM] Ali Diaa: Scientists are developing a new space cannon to shoot objects from the surface of the Earth directly into a low orbit around the Earth.
