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.

After a magnetic field is applied, how many energy levels would you expect for then=3,ℓ=2 state, including electron spin?
zloy xaker [14]

Answer:

The energy level is 5.

Explanation:

Given that,

n = 3

l = 2

We know that,

l shows the number of sub-shells and define the number of angular nodes.

n shows the number of electron shell.

m_{l} is a quantum number. It is define the number of energy level in a sub-shells .

m_{s} is define the spin of the electron.

So, The quantum number is

m_{l}=-2,-1,0,1,2

m_{s} is +\dfrac{1}{2} and -\dfrac{1}{2} for every energy level.

The energy level is 5.

Hence, The energy level is 5.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical
MaRussiya [10]

The coefficients in order are 2, 1, 1

<h3>What is balanced chemical equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.

In other words, the mass and the charge are balanced on both sides of the reaction.

According to the given situation,

To balance the the chemical equation,

Step 1 - Add a 2 on the Na2HPO4:

2(Na₂HPO₄)  ⇒ Na4P₂O₇ + H₂O

Step 2 -Next take count of each element on both sides to see if the 2 is balanced or not:

On the left there are 4 Na, 2 H, 2 P, and 8 O

On the right there are 4 Na, 2 H, 2 P, and 8 O

Step 3 - Now we will divide by 2

i.e. 2 NA.H. P

The coefficient of  Na is 2 , Coefficient of H is 1 and Coefficient of P is 1

Therefore,

The coefficients in order are 2, 1, 1.
