Aspacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 480 kg. it has strayed too close to a black hole having a mass 90 times that of the sun. the nose of the spacecraft points toward the black hole, and the distance between the nose and the center of the black hole is 10.0 km.

what is the difference in the gravitational field acting on the occupants in the nose of the ship and on those in the rear of the ship, farthest from the black hole? this difference in acceleration grows rapidly as the ship approaches the black hole. it puts the body of the ship under extreme tension and eventually tears it apart.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
