Answer:
A
Explanation:
PRECISION AND ACCURACY ARE TERMS THAT ARE USED TO INDICATE THE QUALITY OF A GIVEN SET OF STATISTICAL OBSERVATIONS.
WHILE PRECISION TALKS ABOUT THE LEVEL OF AGREEMENT AMONGST THE SAME SET OF DATA OBSERVATIONS, ACCURACY TALKS ABOUT HOW FAR OR HOW CLOSE THE TRUE VALUE IS TO THE CALCULATED VALUE. TAKING AN AVERAGE OF ALL THE VALUES, IT STANDS AT 4.735 WHICH IS QUITE CLOSE TO THE TRUE VALUE OF 4.75
NOW, LOOKING AT THE SPREAD OF THE VALUES IN THE OBSERVATION, WE CAN SEE THAT THESE VALUES ARE QUITE NOT CLOSE TO EACH OTHER. HENCE, WE CAN CONCLUDE THAT ALTHOUGH HIS OBSERVATIONS ARE QUITE QUITE ACCURATE BASED ON THE OVERALL AVERAGE, WE CAN CONFIDENTLY POSIT THAT HIS VALUES HAVE A LOW LEVEL OF PRECISION
Given what we know, we can confirm that in Reno, NV, the angle of the Sun is lower during the winter months and <u>higher </u>in the <u>sky </u>during the summer.
<h3>How can we know this?</h3>
We can know this about Reno, NV, given that it is irrelevant where we placed this question. the answer will be the same all across the world. It has to do with the way the Earth orbits the Sun as well as the tilt of the Earth. This causes the Sun to be higher in the sky during summer and lower in the winter months.
Therefore, we can confirm that the angle of the Sun is lower during the winter months and higher in the sky during the summer, both in Reno, NV and everywhere else.

The answer is
6.8 * 10^-15
The explanation:
1- we have to convert all measurements to the same units:
Conversions:
when 1 m = 100 cm
and 1 m = 10^12 pm
So,
proton radius: 1.0*10^-13 cm * (1m / 100 cm) = 10^-15 m
proton volume: 4/3 * pi * r^3 = 4/3 * pi * (10^-15 m)^3 = 4.2 * 10^-45 cu. meters
and
H atom radius: 52.9 pm * (1m / 10^12 pm) = 5.29 * 10^-11 m
H atom volume: 4/3 * pi * r^3 = 4/3 * pi * (5.29 * 10^-11 m)^3 = 6.2 × 10^-31 cu. meters
So,
2- Fraction of space occupied by nucleus = proton volume / H atom volume
= (4.2 * 10^-45 cu. meters) / (6.2 × 10^-31 cu. meters)
= 6.8 * 10^-15
So, the "fraction" would be 6.8 * 10^-15 out of 1.
Its true, because it does balance the equations account for the conversation of the mass.
