Answer:

velocity and wavelength

Explanation:

When a ray of light moves from one medium to another, the ray of light changes the direction when it enters the second medium, refraction of light occurs.

When it changes the direction, the frequency will remain the same because it depends only on the source not on the medium.

As the refractive index of two medium is not same, it means the wavelength will change.

Also, speed = frequency × wavelength

So, wavelength and velocity changes. Hence, the correct option is (a).

How can you make the potential energy as high as possible in a magnetic field between one electromagnet and one piece of iron?

harkovskaia [24]

In step 1, to increase the potential energy, the iron will move towards the electromagnet.

In step 2, to increase the potential energy, the iron will move towards the electromagnet.

<h3>Potential energy of a system of magnetic dipole</h3>

The potential energy of a system of dipole depends on the orientation of the dipole in the magnetic field.

$U = \mu B$

where;

$\mu$ is the dipole moment
B is the magnetic field

$B = \frac{\mu_0 I}{2\pi r}$

$U = \mu\times (\frac{\mu_0 I}{2\pi r} )$

Increase in the distance (r) reduces the potential energy. Thus, we can conclude the following;

In step 1, to increase the potential energy, the iron will move towards the electromagnet.
In step 2, when the iron is rotated 180, it will still maintain the original position, to increase the potential energy, the iron will move towards the electromagnet.

What is the momentum of a bowling ball with mass of 8.9 kg and a speed of 6.0 m / s

PtichkaEL [24]

Answer:

The momentum of the bowling ball is 53.4 kg-m/s.

Explanation:

We have,

Mass of a bowling ball is 8.9 kg

Speed of the ball is 6 m/s

It is required to find the momentum of the ball. The momentum of an object is given in terms of its mass and speed as :

p = mv

$p=8.9\times 6\\\\p=53.4\ kg-m/s$

So, the momentum of the bowling ball is 53.4 kg-m/s.
