Question1

A neutron star and a black hole are 2.400e+12 m from each other at a certain point in their orbit. The neutron star has a mass of 2.78×1030 kg and the black hole has a mass of 9.94×1030 kg. What is magnitude of the gravitational attraction between the two?

Question2

The diameter of the sun is 865,000 miles (use the radius) and distance to the sun is 93,000,000 miles. Utilize a scale with 1 mm as the radius of the sun. How many millimeters from the sun would the earth is using this scale?

Question3

The radius of a hydrogen nucleus is 1.4*10^-15 meters. Total hydrogen atom has a radius of .53A or 5.3*10-11m. How numerous times larger is the atom than its necleus?

A. 7.2*10^-16

B. 1.93*10^-15

C. 3.8*10^4

D. 7.2*10^4

 A coil of wire is connected to a galvanometer. When a bar magnet is moved in and out of the coil, the galvanometer records a current. The current results because: pick the b A 650kg elevator starts from rest and moves upwards for 3sec with aconstant acceleration until it reaches a cruising speed of1.75m/s.
