Aspacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1490kg. it has strayed too close to a black hole having a mass97 times that of the sun. the nose ofthe spacecraft points toward the black hole, and the distancebetween the nose and the center of the black hole is 10.0 km.

(a) determine the total force on thespacecraft.
(b) what is the difference in the gravitational fields acting onthe occupants in the nose of the ship and on those in the rear ofthe ship, farthest from the black hole? this difference inacceleration grows rapidly as the ship approaches the black hole. it puts the body of the ship under extreme tension and eventuallytears it apart.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
