Answer:

5°  

Explanation:

Two diverging light rays, originating from the same point, have an angle of 5° between them.

According to laws of reflection the angle of incidence is equal to the angle of reflection.

From the attached figure, it is clear that the after reflection from a plane mirror the angle between two rays will be 5°.

O be the originating point. m and n two diverging light rays. When they strikes at the plane mirror, the laws of reflection still fulfilled.

As a reference, consider the line from the point perpendicular to the mirror.
That direction is called 'normal' to the mirror.

The ray on the right leaves the point traveling 5° to the right of the normal,
and leaves the mirror on a path that's 10° to the right of the normal.

The ray on the left leaves the point traveling 5° to the left of the normal,
and leaves the mirror on a path that's 10° to the left of the normal.

The angle between the two rays after they leave the mirror is 20° .

Frankly, Charlotte, if there were more than 5 points available for this answer,
I'd seriously consider giving you a drawing too.

If you have (1 x 10⁹) cubic meters of volume, and 1/2 gram of mass
in each cubic meter, then you have

          (1/2 x 10⁹) grams = (5 x 10⁸) grams = (5 x 10⁵) kilograms of mass . 

On Earth, that mass weighs  4,900,000 newtons .

How much heat is needed to raise the temperature of 50.0 g of water by 25.0°C
love history [14]

Answer:

Explanation:

In order to be able to solve this problem, you will need to know the value of water's specific heat, which is listed as

c

=

4.18

J

g

∘

C

Now, let's assume that you don't know the equation that allows you to plug in your values and find how much heat would be needed to heat that much water by that many degrees Celsius.

Take a look at the specific heat of water. As you know, a substance's specific heat tells you how much heat is needed in order to increase the temperature of

1 g

of that substance by

1

∘

C

.

In water's case, you need to provide

4.18 J

of heat per gram of water to increase its temperature by

1

∘

C

.

What if you wanted to increase the temperature of

1 g

of water by

2

∘

C

? You'd need to provide it with

Now let's say that you wanted to cause a

This means that in order to increase the temperature of

m

, you need to provide it with

This will account for increasing the temperature of the first gram of the sample by

, of the the second gram by

, of the third gram by

C

, and so on until you reach

m

And there you have it. The equation that describes all this will thus be

, where

q

- heat absorbed

m

- the mass of the sample

c

- the specific heat of the substance

- the change in temperature, defined as final temperature minus initial temperature

In your case, you will have
