Technician A says that one of advantages of a clutch brake is its ability to bring a vehicle to a halt at low speeds. Technician
djverab [1.8K]

Answer:

Option B

Explanation:

  • The advantage of using a clutch brake is that it is capable of handling high load torque and ensures safety at high rotational speeds.
  • The motivation behind a clutch brake is to stop or slow the information shaft from turning, enabling the apparatuses to work without pounding/conflicting. This kills harm to non-synchronized transmissions, and limits the exertion required when moving from impartial into first or switch from a halt.

The velocity of a 0.25kg model rocket changes from 15m/s [up] to 40m/s [up] in
vivado [14]

The force the escaping gas exerts of the rocket is 10.42 N.

<h3>Force escaping gas exerts</h3>

The force the escaping gas exerts of the rocket is calculated as follows;

F = m(v - u)/t

where;

  • m is mass of the rocket
  • v is the final velocity of the rocket
  • u is the initial velocity of the rocket
  • t is time of motion

F = (0.25)(40 - 15)/0.6

F = 10.42 N

Thus, the force the escaping gas exerts of the rocket is 10.42 N.
