A magnetic B field of strength 0.4 T is perpendicular to a loop with an area of 1 m2. If the area of the loop is reduced to zero

Norma-Jean [14]

Answer:

The magnitude of the induced e.m.f is 571 mV

Explanation:

Given;

magnetic field strength, B = 0.4T

area of the loop, A = 1m²

time = 0.7s

Since the angle of inclination of the magnetic field, then the direction of the induced e.m.f, θ = 0

According to faraday's law; the induced emf is directly proportional to the rate of change of flux.

Thus, magnitude of the induced e.m.f is given as

$E.M.F = \frac{\delta \phi}{\delta t} \\\\\phi = BAcos \theta = BAcos0 = BA\\\\E.M.F = \frac{0.4 X1}{0.7} = 0.571 V$

A rubber toy duck is at rest on an inclined plane. When the angle of inclination of the plane is increased to 36.0°, the toy duc

ch4aika [34]

Answer

toy begins to slide when the plane is at an angle of 36.0°

at this point the toy has just overcome the static friction

$f_s = \mu_s N$

$f_s = \mu_s mgcos \theta$

since toy begins to slide

$f_s = mgsin \theta$

now on comparing

$mgsin \theta = \mu_s mgcos \theta$

$\mu_s = tan \theta$

$\mu_s = tan (36^0)$

$\mu_s = 0.726$

as the body is moving at constant velocity acceleration will be zero

so now,

$m g sin \theta - f_k = ma$

$m g sin \theta - \mu_k mg cos\theta = 0$

$\mu_k = tan \theta$

$\mu_k = tan (29^0)$

$\mu_k = 0.554$

Answer plzz<br>How do we apply Interval Training to our lower body for a workout?

weqwewe [10]

Interval training is simply alternating short bursts (about 30 seconds) of intense activity with longer intervals (about 1 to 2 minutes) of less intense activity. For instance, if your exercise is walking and you're in good shape, you might add short bursts of jogging into your regular brisk walks.
