Answer:
Protons = 50
Mass number = 119
Explanation:
A neutral of tin, Sn, has a Z value of 50 and neutrons are 69.
Z is the atomic number. The atomic number is equal to number of protons or number of electrons in an atom that is neutral i.e:
Z = PROTONS = ELECTRONS
So the number of protons = 50 since Z is 50
>>>>>>>>>>>>>>>¦
The bulk of the mass of an atom is concentrated in the nucleus. To calculate mass number, we simply sum all the elementary particles in the nucleus i.e protons and neutrons. These particles are called the nucleons.
Mass number (A) = P + N
= 50 + 69
= 119
There was more force applied therefore there was more movement. Hope this helps.
Answer:
Yes
Explanation:
The velocity measured by Jennifer and Johnny is
The actual velocity is
We can calculate the % error of the students measurement as follows:
Which is lower than the 2.5% maximum error required, so the two students will pass the test.
Commensalism: only one species benefits while the other is neither helped nor
harmed
so the relationship is Commensalism
