My Notes A flat loop of wire consisting of a single turn of cross-sectional area 7.80 cm2 is perpendicular to a magnetic field t

Nastasia [14]

Answer:

0.00158 A

Explanation:

A = Area of loop = 7.8 cm²

$B_f$ = Final magnetic field = 3.2 T

$B_i$ = Initial magnetic field = 0.5 T

R = Resitance = $1.3\ \Omega$

The emf is given by

$E=\frac{(B_f-B_i)A}{t}\\\Rightarrow E=\frac{(3.2-0.5)\times 7.8\times 10^{-4}}{1.02}\\\Rightarrow E=0.00206\ V$

The current is given by

$I=\frac{E}{R}\\\Rightarrow I=\frac{0.00206}{1.3}\\\Rightarrow I=0.00158\ A$

The resulting induced current in the loop is 0.00158 A

What is the acceleration of a car that starts from rest and achieves a speed of 45 m/s in 5 seconds?

bagirrra123 [75]

Answer:

9m/s^2

Explanation:

solution,

Given. Initial velocity (u)=0m/s

Final velocity (v)=45m/s

Time taken(t)=5sec

Acceleration (a)=?

we know,

a=v-u/t

=45-0/5

=45/5

=9m/s^2

Therefore acceleration (a)= 9m/s^2

An alternating current is supplied to an electronic component with a rating that the voltage across it can never, even for an in

Vsevolod [243]

Answer:

A) $V_{rms}=8\sqrt{2} V$

Explanation:

Maximum voltage = $V_{max}=16 V$

Maximum voltage and rms voltage are related to each other by

$V_{max}=V_{rms} \times \sqrt{2} \\V_{rms}=\frac{V_{max}}{ \sqrt{2}}\\V_{rms}=\frac{16}{\sqrt{2}} \\V_{rms}=8\sqrt{2} V$

For a spring oscillating in simple harmonic motion, at what point will the velocity of

Crazy boy [7]

Answer:

equilibrium position.

Explanation:

In simple harmonic motion , velocity v(t) is given by,

v(t) = -ω A sin(ωt + φ)

where

ω = angular velocity of the corresponding circular motion

A = amplitude

t = time

φ = the initial angle of the corresponding circular motion when the motion begin.

v (t) get maximized when sin value is maximized , i.e. sin $\alpha$ =1

The particle has maximum speed when it passes through the equilibrium position.
