A square 1300-turn coil with the area of 0.2 m2 is situated in the xy-plane in a region where the magnetic field is (50k) μT. Wh

givi [52]

Answer:

e = 65 mA

Explanation:

given,

number of turn = 1300

Area = 0.2 m²

B = 50 x 10⁻⁶T

t = 0.2 s

coil rotate in x-z plane

θ = 90° to θ = 0°

maximum induced emf

$e = -\dfrac{BAn(cos \theta_f - cos\theta_i)}{\Delta t}$

$e = -\dfrac{1300 \times 0.2 \times 50\times 10^{-6}(cos 90^0- cos0^0)}{0.2}$

e =0.065

e = 65 mA

Which properties define light as a wave?

Naddik [55]

Properties that define the light is a wave are

1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave

2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.

3. colour

A policeman investigating an accident measures the skid marks left by a car on the horizontal road. He determines that the dista

sleet_krkn [62]

<h2>The velocity of car was m m/s </h2>

Explanation:

When the car skids , its centripetal force is provided by frictional force .

Here centripetal force F = $\frac{mv^2}{r}$

here v is the velocity of car and r is the radius of the curve .

The frictional force f = μ R

here μ is the coefficient of kinetic friction and R is normal reaction

Thus f = m g

On horizontal road R = mg

Thus F = f at the time of skid .

Thus v = $\sqrt{\mu rg}$

= $\sqrt{0.29x23.74x10}$ = 9 m/s
