Answer:
-0.44 N
Explanation:
Applying,
E = -(BANsinФ)/t........................ Equation 1
Where E = E.m.f induced in the coil, B = magnetic field A = Area of the coil, N = Number of turns, Ф = angle between the field an the plane, dt = change in time.
Given: N = 2526 turns, B = 0.27 T, t = 1.9 s, Ф = 90° (perpendicular)
A = Area of a square = L² = 0.035² = 1.225×10⁻³ m²
Substitute into equation 1
E = -0.27(2526)(1.225×10⁻³)(sin90°)/1.9
E = -0.44 N
The frequency of wave B is half the frequency of wave A
Explanation:
The wavelength, the speed and the frequency of a wave are related by the wave equation:
where
v is the speed of the wave
f is its frequency
is its wavelength
The equation can also be rewritten as
In this problem, we have wave A with wavelength and speed v, so its frequency is
Then we have wave B, whose wavelength is twice that of wave A:
And its speed is the same; Therefore, its frequency is
So, the frequency of wave B is half that of wave A.

Answer:
b. The voltage across the resistor is equal to the terminal voltage of the battery, and the voltage across the capacitor is zero.
Explanation:
<em>When the system reaches its steady state the current tends to zero, then</em>
<em>in the resistor</em>
<em>V=IR</em>
<em>I=0, then </em><em>V=0</em>
<em>the capacitor charged is like an interruption in the circuit. </em><em>If we mesure voltage on both sides of the battery and if we mesure both sides of the capacitor, we will get the same value</em><em>, as its not any component between them in one side, and, in the other, the only component is the resistor that, without any courrent doesn't discipates any energy.</em>
