The rotor in a certain electric motor is a flat, rectangular coil with 80 turns of wire and dimensions 2.50 cm by 4.00 cm . The

rotor rotates in a uniform magnetic field of 0.800 T . When the plane of the rotor is perpendicular to the direction of the magnetic field, the rotor carries a current of 10.0 mA . In this orientation, the magnetic moment of the rotor is directed opposite the magnetic field. The rotor then turns through one-half revolution. This process is repeated to cause the rotor to turn steadily at an angular speed of 3.60×10³ rev/min. (b) Find the peak power output of the motor.

The Peak power output of the motor is 0.452 Watt

To find the peak power output, the given values are,

No .of turns of the wire = 80

Dimensions is given as, 2.50 cm by 4.00 cm

Magnetic field = 0.800 T.

current = 10 mA.

Angular speed = 3.60 ×10³ rev/min

<h3>What is Peak power output?</h3>
  • Peak power output can be also known as Peak work rate.
  • If the output was greatest or the work production was very high in the given amount of time then it is known as Peak power output.
  • This peak power is depends on the force, distance and time.

The formula for peak power output,

                     Pout = τ * ω

where,

Pout - output power  watts (W),

τ - torque   Newton meters (Nm),

ω - angular speed  radians per second (rad/s).

Calculating angular speed as here rotational speed of the motor in rpm is given:

                      ω = rpm * 2π / 60

where,

ω – angular speed, radians per second (rad/s),

rpm – rotational speed in revolutions per minute,

π – mathematical constant pi (3.14),

60 – number of seconds in a minute.

So, the formula is,

Peak power output = τ *rpm * 2π / 60

τ = NIAB sinθ Nm

  = 80×10×10⁻³×0.0250×0.040×0.800× Sin 90°

  = 2 × 6.4 × 10 ⁻⁴

  = 1.2 × 10⁻⁴ Nm.

Peak power output = 1.2 × 10⁻⁴ ×3.60×10³ × 2π / 60

= 0.452 Watt

Thus, the peak power output is 0.452 Watt.

How do scientists use inference?
alexgriva [62]
Their inferences are based on evidence that they collect during their investigations. Readers learn that scientists gather and interpret evidence and draw conclusions based on this evidence. ... Once scientists have gathered evidence, they use it to make inferences about the things they are investigating.

myrzilka [38]

Answer:

the distance between the​ lawyer's home and her office is 124 miles

Explanation:

given information:

first lets assume that

x-axis (west = positive, east = negative)

y-axis (north = positive, south = negative)

thus,

distance of the house = (-88,18)

distance of the office = (13, -54)

thus, the distance between the​ lawyer's home and her office

R = √(x₂ - x₁)² + (y₂ - y₁)²

   = √(13 - (-88))² + (-54 -18)²

   = 124 miles
