Answer:
10.0 ml and 35.0ml respectively
Explanation:
if A=10.0ml let B be x
Now,
Lets assume the pan is balanced
then,
x = 10.0 ml
Therefore B= 10.0 ml
[Repeat the same process in next question]
Closer=Burn
Farther=Freeze
We are the perfect distance away from the sun for it to sustain life.

Answer:
detail is given below.
Explanation:
The charged particles of nucleus are protons while neutrons are neutral having no charge.
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus.
Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.
one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.
While the atomic number is 20.
