A loop of area 0.0633 m^2 is oriented perpendicular (0 deg) to a magnetic field. The magnetic field changes in strength from 0.8
frez [133]

Answer:

The magnetic flux change is 0.0877 Wb.

Explanation:

Given that,

Area = 0.0633 m²

Angle = 0°

Magnetic field changes

B_{1}=0.894\ T

B_{2}=2.28\ T

We need to calculate the magnetic flux change

Using formula of flux

\Delta \phi=BA\cos\theta

\Delta \phi=A(B_{f}-B_{i})\cos\theta

Where, B = magnetic field

A = area

Put the value into the formula

\Delta \phi =0.0633\times(2.28-0.894)

\Delta \phi=0.0877\ Wb

Hence, The magnetic flux change is 0.0877 Wb.

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.
