A rocket in outer space is traveling toward a far-off planet. An astronaut turns on the rocket’s engines, which exerts a force o
vazorg [7]

Answer:

It will continue moving at a constant speed because no forces are acting on it.

Explanation:

By the second law of Newton, the force is proportional to the acceleration. If there is no force, there is no acceleration. So, when the astronaut turns off the engines, the rocket will have no acceleration which means that the speed will be constant.

Therefore, the answer is:

It will continue moving at a constant speed because no forces are acting on it.

Technician A says that if starter drive clearance is too small, the starter will produce a noise during cranking. Technician B s
Ronch [10]

Answer:

Both Technicians A and B are wrong in there answers.

Explanation:

Starter Drives are rotating mechanical component use to drive another component (flywheel) to start an engine. And thus they are known as starters. Starters are smaller than the component they drive. They are found commonly in automobiles.

The starter and the driven component(gear) are supposed to fit closely, with some clearance between the two gears so as to operate without noise. When the<u> clearance is too small </u>there will be a <u>noise after cranking,</u>  and   when the <u>clearance is too great</u> there be <u>noise before cranking</u>.

Cranking simply means starting an engine or the initial rotating of an engine to start it.
