A total solar eclipse is visible from

Physics

leonid [27]3 years ago

Answer:

b. only within the moon’s umbra.    

Explanation:

A total solar eclipse occurs when the moon blocks the sunlight falling on the Earth. It occurs at the bright side of the Earth when Earth passes through the umbra of the moon.

When sun, moon and Earth align in a straight line, the disk of the moon is able to block the disk of the sun causing the sunlight to get blocked. Shadow of moon falls on the Earth. A total eclipse occurs when the sun is complete blocked and there is total darkness. It is visible from those areas which pass through the moon's umbra.

Hey! Hope that this helps. I'm fairly certain the answer is B, because I know that it's not visible from all over the earth, so that eliminates A, but doing some research I found out that an observer in the umbra experiences a total eclipse.

Can anyone help me with factor-label method for physics (in pic)
seropon [69]
Hello there!

I can help you out with #15 to help get you started/ unstuck! :)

So I see you have your conversion table drawn! Fantastic!

So you start off by putting the GIVEN unit in the first (top) space.

12 g

Next, you put " 1 g " ( 1 gram ) below, and to the right of it. (Diagonal right 1 block).

Why 1 gram? Because the units g will cancel each other out!

So on the box NEXT to your 12 g, put ___kg. This will give you your new unit.

For now, you can search up how many kilograms there are in a gram but it'll be very helpful in the future to have it memorized. :)

Clarification:

"How many kg are there in a g?"

We do this because the bottom says " 1 gram," so since we're converting grams to kilograms, we're converting 1 gram to ___ kilograms.


After filling out your chart, multiply the tops together! Cancel out units, and use a calculator if it's allowed! :)

Summary:

1). Make an empty conversion table.
2). Start with the given unit in the top left space.
3). Move down, and to the right: Put 1 (unit). This will cancel the units out later.
4). Above the 1 (unit), put (???) (new unit).

To find (???) simply search it up. :)

Ex). "How many kg are there in 1 g?"

The units should cancel out on their own. :)

With this, it simply takes practice. I'm sure you'll get the hang of it in no time! :D

What is the wavelength of microwaves of 3.0 X 10^9 Hz frequency?
GarryVolchara [31]
Given,

Frequency of microwaves = 3 x 10^9 Hz

We know that,

Velocity (c) = Frequency x Wavelength
Velocity of light (c) = 3 x 10^8 m/s

Therefore,

Wavelength = Velocity ÷ Frequency = (3 x 10^8) ÷ (3 x 10^9) = 0.1 m

A beaker of water is heated to increase its solubility, and it is saturated with a solid solute compound, such as salt. Then the
Nimfa-mama [501]

Answer:

The solid crystal will precipitate.

Explanation:

Solubility indicates how much solid can be in solution without it precipitating and depends on the temperature for most salts or compounds, increasing as the temperature rises.

Therefore, if the beaker is heated, more solid will remain in solution, in this case until saturation (the maximum amount of the solid that can be in solution without it precipitating).

As the temperature drops, the solubility drops, therefore any amount of solid that is added additionally will precipitate.
