Answer:

A force is a push or pull upon an object resulting from the object's interaction with another object.

Momentum is force or speed of movement.

Velocity defines the path of the motion of the frame or the object

The magnetic field on the axis of a circular current loop (Eq. 5.41) is far from uniform (it falls off sharply with increasing z

Allisa [31]

Answer:

Part b

$B = 8\frac{\mu_o I}{5\sqrt5 R}$

Explanation:

Part a)

Let the radius of the coil is R and magnetic field on its axis is given as

$B = \frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}}$

now we know that two coils are identical and we need to find magnetic field between two coils

so we will have net magnetic field given as

$B = \frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}} + \frac{\mu_o I R^2}{2((d-z)^2 + R^2)^{3/2}}$

Now we know that magnetic field is maximum at position

$\frac{dB}{dz} = 0$

so we will have

$z - (d - z) = 0$

$z = \frac{d}{2}$

so it will be at mid point of two coils

Part b)

Now we know that

$\frac{d^2B}{dz^2} = 0$

so we will have

$d = R$

now magnetic field is given as

$B = 2\frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}}$

put z = 0.5 R

$B = 8\frac{\mu_o I}{5\sqrt5 R}$

A ray of light traveling in glass (refractive index na) reflects at the flat interface between the glass and water (refractive i

pickupchik [31]

Answer:

θr will increase.

Explanation:

We know that when light travel from one medium to another medium the relationship between refractive index and angle given as

na. sinθa = nb . sinθr

$sin \theta _r=\dfrac{n_asin\theta _a}{n_b}$

If na is increased (by using a different type of glass) but θa is kept the same then sinθr will also increase.

So answer is θr will increase.

If you have 4 kg of a sample with density of 1 897 g/ml what is the volume

Kaylis [27]

We know, Volume = Mass / Density
Here, mass = 4 Kg = 4000 g
d = 1,897 g/ml

Substitute their values,
v = 4000 / 1897
v = 2.108 ml

In short, Your Answer would be 2.108 mL

Hope this helps!
