Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

Physics
1 answer:
Arlecino [84]3 years ago
5 0

Answer:

light is refracted towards the normal.

Explanation:

The more dense medium have a higher refractive index and so the light slows down towards the normal.

When the Sun, Earth, and Moon are in this position, the high tides will be lower than normal levels because
Gnesinka [82]
Ok, I’ll try to help, but I’d need to see the picture of the positions of the sun, earth, and moon to help you fully.

So, the first thing to note is that gravity is an attractive force, meaning that; something that has mass, call the m1 will “pull toward” another mass, call it m2. The two objects pull on each other, mutually.

If an object has more mass it pull more, and if an object has less mass, it pulls less.

Another thing to note is that distances matter. The closer the objects are to each other, the more pull they’ll “feel”.

So, the ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than the sun does. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.

So, when the bulge of the ocean caused by the sun’s gravity, partially cancels out the bulge of the ocean caused by the moon gravity. This produces moderate tides known as the neap tides, meaning that high tides are a little lower and low tides are a little higher than average.

I hope that helps.

The drift velocity should be in the same direction as the applied force. <br> a. true <br> b. false
Marina CMI [18]

It is a false statement i.e. drift velocity is not same in the direction as the applied force.

Drift velocity of a  current-carrying conductor can be explained as, the charges i.e. electrons do not  flow in the same direction of current. In other word, in most cases the movement of the electrons is almost random, with a small net velocity. So that , the drift velocity, in the direction opposite to the electric field.

Drift velocity v_{d} is inversely proportional to the number of electron per unit volume of the conductor e. Therefore, the formulation can be given as ,

v_{d} = σ E/ne

The above equation shows the drift velocity in a current carrying conductor  

where, v_{d} is drift velocity , σ is the conductivity, E is electric force and n is number of electrons per unit volume of the conductor e.

Hence here we can say that, the drift velocity is not in the same direction as the applied force.

Stels [109]

Answer:

115.05 Volts

Explanation:

We can use Ohm's Law!

V=IR

V= 1.77 * 65

V=115.05 Volts
