External budding gemmules
Answer:
10. D
9. A
8. A or B
Explanation:
10. Calcium has 20 electrons, but the Calcium ion has 18 electrons.
9. The mass of electrons are negligible.
8. Electrons have a very small mass where some consider it to have no mass.
More potential energy would be stored in the magnetic field, and the spacecraft magnet would travel farther/faster.
<h3 /><h3 /><h3>What is Potential energy?</h3>
- This is the work done in moving a charged particle to a certain distance in magnetic field.
When an object is moved against a stronger magnetic force, it transfers more energy to the magnetic field because magnetic forces are stronger when magnets are closer.
The more energy gained in the magnetic field causes the spacecraft to travel faster and farther.
Thus, more potential energy would be stored in the magnetic field, and the spacecraft magnet would travel farther/faster.

<span>Use Root mean square speed formula:
vrms = Sqrt (3RT/M)
T - temperature in K = 273K - 21CÎż = 252K
R- molar gas constant = 8.31J/Kmol
M - molar mass of a molecule
MN2 = 14x2 = 28 g/mol
MO2 = 16 x 2 = 32 g/mol
MO3 = 16 x 3 = 48 g/mol
Having all info now, you can calculate root mean square speed,vrms ,
for every molecule by using the aboveequasion and only changing M value.</span>
