<span>The option A is correct answer. The isotopes are X and Y. The isotopes are those which have same atomic number but different mass number. Since atomic number has same number of protons or electrons. Thus, isotopes have same number of protons or electrons. Therefore, X and Y are isotopes.</span>
The elephant has more inertia than the dog so it takes more force to change the motion of the elephant.
Answer:
The answer to your question is P2 = 280 mmHg
Explanation:
Data
Pressure 1 = P1 = 400 mmHg
Volume 1 = V1 = 1.75 L
Pressure 2 = ?
Volume 2 = 2.5 L
Process
1.- Use Boyle's law to solve this problem
P1V1 = P2V2
-Solve for P2
P2 = P1V1 / V2
2.- Substitution
P2 = (400)(1.75) / 2.5
3.- Simplification
P2 = 700 / 2.5
4.- Result
P2 = 280 mmHg
Answer:
the answer to this question is producer
