24. A 50-turn coil has a diameter of 15 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.50 T so that
finlep [7]

Answer:

0.1 = 4.42v

1.0 =0.44v

60 = 7.4 × 10^-3 V

Explanation:

Apply the formula of:

Emf = (No of turns × magnetic flux)÷(the given time)

Where your magnetic flux = (0.50 × cross sectional area(pi × 0.075^2))

Sunlight is used in a double-slit interference experiment. The fourth-order maximum for a wavelength of 460 nm occurs at an angl
Svet_ta [14]

Answer:

a)λ  = 6.133 10⁻⁷ m = 613.3 nm, b) d = 1.60 10⁻⁶ m , c) Δd = 0.24 10⁻⁶ m

Explanation:

The expression that describes the interference phenomenon for the double slit is

         d sin θ = m λ          m = ±1, ±2,…

a) Let's use the data to find the separation of the slits (d)

        d = m λ / sin θ

       d = 4 460 10⁻⁹ / sin 90

       d = 1.84 10⁻⁶ m

Now we can calculate the minimum wavelength for the third orcen (m = 3), the maximum angle must be 90 °

        λ  = d sin θ / m

        λ  = 1.84 10⁻⁶ sin 90 / 3

        λ  = 6.133 10⁻⁷ m

This is the last visible wavelength in this interference order, that is, we see the light with a shorter length than the calculated

b) To eliminate all the light of the fourth order (m = 4) let's use the minimum wavelength of visible range ( λ = 400 nm) from a 90 ° angle

          d = m  λ  / sin θ

          d = 4  400 10⁻⁹ / sin 90

         d = 1.60 10⁻⁶ m

If we reduce the slit to this value, the spectrum for the fourth order can be used.

c) It is change of separation is

          Δd = d₂ - d₁

          Δd = (1.84 - 1.60) 10⁻⁶ m

          Δd = 0.24 10⁻⁶ m

In a heat engine, Qh and Qc represents high temperature substance and low temperature substance respectively. Which of the follo
ElenaW [278]

The efficiency of a heat engine is given by the expression eff =\frac{Q_h-Q_c}{Q_h}

The efficiency of a heat engine is the ratio of the work done by the engine to the heat given as the input to the engine.

eff =\frac{W}{Q_h}

The heat engine absorbs Q h from the hot reservoir , performs a work <em>W</em> on the absorbed heat and rejects Qc to the cold reservoir.

Therefore, the work done  is given by,

W=Q_h - Q_c

Thus the efficiency is given by, eff =\frac{Q_h-Q_c}{Q_h}
