A 25-turn circular coil of wire has diameter 1.00 m. It is placed with its axis along the direction of the Earth’s magnetic fiel

slava [35]

Answer:

The magnitude of average emf is 9.813 mV.

Explanation:

Given that,

Number of turns = 25 turns

Diameter = 1.00 m

Magnetic field = 50.0μm

Time = 0.200 s

Angle = 180°

We need to calculate the area of the coil

Using formula of area

$A=\pr r^2$

$A=\pi\times(\dfrac{1.00}{2})^2$

$A=0.785\ m^2$

We need to calculate the average emf

Using formula of emf

$E=NAB\cos\theta$

$E=NA(\dfrac{B\cos0^{\circ}-B\cos180^{\circ}}{dt}$

$E=\dfrac{2NA}{dt}$

Where, N = number of turns

A = Area

B = magnetic field

Put the value into the formula

$E=\dfrac{2\times25\times0.785\times50.0\times10^{-6}}{0.200}$

$E=9.813\ mV$

Hence, The magnitude of average emf is 9.813 mV.

Estimate the order of magnitude of the length in meters of each of the following: a. a ladybug b. your leg c. your school buildi

sukhopar [10]

The order of the magnitude of the length in meters is estimated based on the average length of the object: if it is a small object then the unit would be cm and if it is a long object (like a road or something) the distance can be measured in km. Then we convert the unit we measured in into the SI unit of the meter.

Based on this, for the mentioned objects, the estimated length would be as follows:
a- ladybug: 10^-2 meters
b- your leg : 10^0 meters
c- your school building : 10^1 to 10^2 meters
d- a giraffe: 10^0 meters
e- city block: 10^2 meters

How is a flywheel constructed to maximize its rotational inertia?

BigorU [14]

Answer:

It is constructed with a high mass and a high raidus.

Explanation:

The rotational inertia I for every object is calculated as:

cMR^2 = I

where c is a constant, M is the mass of the object and R the radius of the object.

So, for a flywheel, the rotational inertia is calculated as:

I = $\frac{1}{2}MR^2$

Then, for constructed a flywheel with the maximun rotational inertia we have to set the maximum mass and the maximun radius.

What is the circle of least confusion?

Artist 52 [7]

Answer and Explanation:

In optics, a CoC(Circle of Confusion) is defined the minimum cross section of a paraxial bundle of rays made by a lens which is sphero-cylindrical type and can be viewed as an optical spot, which do not converge perfectly at the focus while a point source is being imaged due to spherical aberration.

The Circle of Confusion is also referred to as circle of indistinctness or a blur spot
