Answer:
1. Who gathered the data that showed planets traveling in elliptical paths around the sun?
2. Who discovered elliptical orbits?
3. Who explained them?
Explanation:
1. Tycho Brahe was the one that gathered data.
2. Johannes Kepler discovered it using Tycho Brace’s Data.
3. I believe it was Johannes Kepler because he created 3 laws of it.
I apologize if it is incorrect-
I hope it helps! Have a great day!

De Broglie's identity gives the relationship between the momentum and the wavelength of a particle:
where
p is the particle momentum
m is its mass
v its velocity
h is the Planck constant
is the wavelength
By re-arranging the equation, we get
and by using the data about the proton, given in the text, we can find the proton's wavelength:
The auditory nerve carries an electrical signal to the brain, which turns it into a sound that we recognize and understand.
Answer: Your code returns a number of 99.123456789 +0.00455679
Ok, you must see where the error starts to affect your number.
In this case, is in the third decimal.
So you will write 99.123 +- 0.004 da da da.
But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.
in the error, after the 4 comes a 5, so it rounds up.
So the final presentation will be 99.123 +- 0.005
you are discarding all the other decimals because the error "domains" them.
