<h2>Answer:</h2>

<u>By wrapping the wire along a solenoid and connecting it to electricity</u>

<h2>Explanation:</h2>

If you wrap a copper wire into coils and run an electrical current through it, you will create a magnetic field. If you rotate a permanent magnet as opposed to an item that has been magnetized inside a coil of copper wire, you can create an electrical current. The strength of magnetic field generated is proportional to the amount of current through the winding.

If |v|= 11, |w|= 23, |v-w|= 30, find |v+w|

GenaCL600 [577]

Answer:

$|v+w|=20$

Explanation:

We are given that

|v|=11

|w|=23

|v-w|=30

We have to find the value of |v+w|

|a-b|^2=(a+b)\cdot (a+b)=a^2+b^2-2|a||b|cos\theta

Using the formula

$(30)^2=(11)^2+(23)^2-2(11)(23)cos\theta$

$900=121+529-506cos\theta$

$900-121-529=-506cos\theta$

$250=-506cos\theta$

$cos\theta=-\frac{250}{506}$

$|a+b|^2=|a|^2+|b|^2+2a\cdot bcos\theta$

Using the formula

$|v+w|^2=(11)^2+(23)^2+2(11)(23)\times (-\frac{250}{506})$

$|v+w|^2=400$

$|v+w|^2=(20)^2$

$|v+w|=20$

How does the speed of light in glass depends on the frequency

Naddik [55]

Answer:

Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical componen

Lana71 [14]

Answer:

sin 30° = $\frac{v_{y} }{25}$

Multiply each side by 25 to cancel the 25 under $v_{y}$

(25)· sin 30° = $v_{y}$

Multiply everything on the left side.

12.5 $\frac{m}{s}$ = vertical velocity component.

I attached a picture, I hope it helps.

What is the magnetic force acting on an electron if its speed is 3.0 × 106 meters/second and the direction is perpendicular to a

bogdanovich [222]

Magnetic force = charge × speed × magnetic field

Fm = (1.6x10^-19)(3x10^6)(0.02)

Fm = 9.60x10^-15 N

^That is the magnitude of the magnetic force. If you want the direction, you will need to know what direction the speed and magnetic field are. Then you can use the left hand straight fingered rule to determine the direction of the force.
