this is how to convert BTU (IT) to Joules:

1 BTUIT = 1055.05585262 J

So the energy conversion from BTU to joules is given by the formula:

E(J) = 1055.05585262 ⋅ E(BTU)

BUT HERE IS THE ANSWER TO YOUR QUESTION

1215424.3422

**Answer:**

On average a galaxy has, between **<u>800 billion and 3.2 trillion planets.</u>**

**Answer:**

The photon has a wavelength of

**Explanation:**

The speed of a wave can be defined as:

** (1)**

Where v is the speed, is the frequency and is the wavelength.

Equation 1 can be expressed in the following way for the case of an electromagnetic wave:

** (2) **

Where c is the speed of light.

Therefore, can be isolated from equation 2 to get the wavelength of the photon.

**(3)**

**Hence, the photon has a wavelength of **** **

<em>**Summary: **</em>

Photons are the particles that constitutes light.

One takes longer to slow down than the other because one has more mass(the train) compared to the bowling ball!
