Suppose we are given a square coil that is 5.5 cm on a side containing 100 loops of very fine wire. The total resistance of this

maw [93]

Answer:

I = 578A

Explanation:

The magnitude of the peak value of the induced current flowing in a coild is given by

$I = \frac{\epsilon_{max}}{R}$

$I = \frac{NBA\omega}{R}$

Where

I= current

N = Number of loops

$\omega =$ angular velocity

R= Resistance

B = Magnetic field

A = Area

Replacing our values we have that,

$I = \frac{(100)(1.3)(0.055)^2(2.5)}{1.7*10^{-3}}$

$I = 578A$

WHAT WILL BE YOUR CONCLUSI0N ABOUT ELECTROMAGNETIC WAVE

andrezito [222]

Answer:

It's really important waves type for fulfill human's needs

Explanation:

Electromagnetic waves are transverse waves composed by the perpendicular oscillating electric and magnetic fields.

EM waves have both Electrical and magnetic features.

they travel in the velocity of light (3*10⁸ ms⁻¹)

they does not require any media to travel. It has two perpendicular electric field and the magnetic field which are perpendicular to each other

They travel perpendicular to each of those electric and magnetic fields.

Example :

Radio Wave
Micro Wave
IR wave
Light Wave
UV rays
X rays
Gamma rays
Cosmic rays

The main importance of em waves is they allow energy to be stored within them and then can be propagated over a large distance using the dielectric and magnetic properties of materials .

This performance has been used in many fields wisely and effectively to make the things easy.

Ex : medicine , Telecommunication , energy , Engineering etc

In a standard tensile test a steel rod of 22-mm diameter is subjected to a tension force of 75kN. Knowing that v = 0.30 and E =

VladimirAG [237]

Answer:

(a) Elongation of rod = 0.19732 mm

(b) Change in diameter = 0.00651 mm

Explanation:

Circular area at end of steel rod = pi * diameter^2 / 4

$Area = pi * (22 * 10^-^3)/4$

Area = 3.801 * 10^(-4) meter squared

Stress = force / area

Stress = 75000 / (3.801 * 10^-4)

Stress = 197316495 Pa OR 0.197 GPa

Modulus of elasticity = stress / strain

200 = 0.19732 / Strain

Strain = 0.0009866 (longitudinal)

(a) Strain = change in length / initial length

0.0009866 = Elongation of rod / 200

Elongation of rod = 0.19732 mm

(b) Poisson ratio = lateral strain / longitudinal strain

0.3 = lateral strain / 0.0009866

Lateral strain = 0.000296

Lateral strain = Change in diameter / original diameter

0.000296 = Change in diameter / 22

Change in diameter = 0.00651 mm
