A horizontal circular wire loop of radius 0.7 m lies in a plane perpendicular to a uniform magnetic field that is pointing down

Maru [420]

Answer:

$\epsilon=1.10\ V$

Explanation:

It is given that,

Radius of the circular loop, r = 0.7 m

Magnetic field, B = 0.44 T

In 0.14 s the wire is reshaped from a circle into a square, but remains in the same plane.

Area of the circular wire,

$A_1=\pi r^2$

$A_1=\pi (0.7)^2=1.539\ m^2$

For the area of square,

The circumference of wire, $C=2\pi r=2\pi \times 0.7=4.39\ m$

Side of square, $l=\dfrac{4.39}{4}=1.09\ m$

Area of square, $A_2=1.09^2=1.188\ m^2$

An emf is induced in the loop due to change in its area. The induced emf is given by :

$\epsilon=-B\dfrac{dA}{dt}$

$\epsilon=-B\dfrac{A_2-A_1}{t}$

$\epsilon=-0.44\times \dfrac{1.188-1.539}{0.14}$

$\epsilon=1.10\ V$

So, the magnitude of the average induced emf is 1.10 volts. Hence, this is the required solution.

Highway transportation officials are trying to determine if the average speed on Archer road is above 45mph, the post speed limi

USPshnik [31]

Answer:

Option D) -0.0707

Explanation:

We are given the following in the question:

Population mean, μ = 45 mp

Sample mean, $\bar{x}$ = 44.9

Sample size, n = 50

Sample standard deviation, s = 10

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{44.9 - 45}{\frac{10}{\sqrt{50}} } = -0.0707$

Thus, the test statistic is

Option D) -0.0707
