Suppose that the magnetic field in some region has the form B = kz ˆx (where k is a constant). Find the force on a square loop (

side a), lying in the yz plane and centered at the origin, if it carries a current I , flowing counterclockwise, when you look down the x axis.

Answer:

F = ika^2

Explanation:

As we know that loop is placed in YZ plane and magnetic field is along x direction

So here net force on the side of the loop which lies along Y axis is given as

F_1 = i (\vec L \times \vec B)

here we know that on Y axis z = 0

so B = 0

so we have

F_1 = 0

now on the opposite side we have z = a

so magnetic field is given as

B = ka

so force on that side is given as

F = i(\vec L \times \vec B)

F = i(a)(ka) sin90

F_2 = ika^2

so net force on the loop is given as

F = F_1 + F_2

F = ika^2

Perhaps to confuse a predator, some tropical gyrinid beetles(whirligig beetles) are colored by optical interference that is duet
gulaghasi [49]

Answer:

The grating spacing of the beetle is 1.078*10^{-6}m

Explanation:

The concept to solve this problem is relate to interference effect given in the Young's Slits. Here was demonstrated that the length of the side labelled \lambda is known as the path difference. The equation is given by,

n\lambda = dsin\theta

Where,

\lambda= wavelenght of light

N = a positive integer: 1,2,3...

\theta = Angle from the center of the wall to the dark spot

d= width of the slit

Replacing our values we have that for n=1,

dsin\theta = n\lambda

dsin(30)=(1)(539*10^{-9})

d=1.078*10^{-6}m

Therefore the grating spacing of the beetle is 1.078*10^{-6}m

What is the difference between vector and scalar ?
ddd [48]
The easiest, non-technical way to think about it is like this:

-- A scalar is a quantity that has a size but no direction.
Those include temperature, speed, cost, volume, distance, etc.

One number is all there is to know about it, and there's no way you can
add more of the same stuff to it that would cancel both of them out.

-- A vector is a quantity that has a size and also has a direction.
Those include force, displacement, velocity, acceleration, etc.

It takes more than one number to completely describe one of these.
Also, if you combine two of the same vector quantity in different ways,
you can get different results, and they can even cancel each other out.

Here are some examples.  Notice that in each of these examples,
every speed has a direction that goes along with it.  This turns the
scalar speed into a vector velocity.

If you're walking inside a bus, and the bus is driving along the road,
then your velocity along the road is the sum of your walking velocity
inside the bus plus the velocity of the bus along the road.

-- If you're walking north up the middle of the bus at 2 miles per hour
and the bus is driving north along the road at 20 miles per hour, then
your velocity along the road is 22 miles per hour north.

-- If you're walking south towards the back of the bus at 2 miles per hour
and the bus is driving north along the road at 5 miles per hour, then your
velocity along the road is 3 miles per hour north.

-- If you're walking south towards the back of the bus at 2 miles per hour
and the bus is just barely rolling north along the road at 2 miles per hour,
then your velocity along the road is zero.

--  If you're in a big railroad flat-car that's rolling north along the track
at 2 miles per hour, and you walk across the flat-car towards the east
at 2 miles per hour, then your velocity along the ground is 2.818 miles
per hour toward the northeast.

An electron is moving in the presence of an electric field of 400 N/C. What force does the electron experience?
yanalaym [24]

Answer:

Explanation:

Given

Electric Field strength E=400\ N/C

charge of electron q=1.6\times 10^{-19}\ C

Force on the charge particle is given by

F=qE

F=1.6\times 10^{-19}\times 400

F=640\times 10^{-19}\ N

but this force will be acting in the direction opposite to the direction of Electric field because electron is negatively charged

What is the kinetic energy of a 150 gram object moving at a velocity of 100 m/s?
Alex Ar [27]

Answer:

750 J

Explanation:

lets convert mass into kg first , 150 /1000 = 0.15 kg

kinetic energy =  \frac{mv^{2} }{2} =  \frac{0.15*100^{2} }{2}  = 750 J
