Do you mean 12 km/h because this is a measurement of distance
The moon phase shows that D. light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
<h3>What is a moon phase?</h3>
It should be noted that the <em>moon</em> phase simply means the portion of the moon that we can see from the Earth.
In this case, the light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.

Because Helium fusion in a shell outside the core generates enough thermal pressure to push the upper layers outward.
Answer:
Option B
Explanation:
Maintenance-free battery uses Recombination Electrolyte in order to limit the oxygen and hydrogen formation during charging.
Each plate of the battery uses a glass micro-fiber separator that absorbs the whole liquid electrolyte in its pore thus resulting in no free acid.
As the battery charges to its fullest, the oxygen produced at the positive plate moves via the pores of the separator to the negative plate.
Initially it reacts and forms , i.e., Lead Sulphate, then on further charging it gets converted to Pb, i.e., lead.
Due to this, the negative plate is not able to reach the correct potential in order to liberate hydrogen, and hence no water formation takes place.
Thus technician B is correct.
If an object has more kinetic energy then its going to take more energy to stop it. a larger car has obviously more mass, meaning more kinetic energy, and a smaller car obviously wouldnt have as much energy, so it would take less to stop it. therefore, the larger an object is, the harder it is to stop. hope i helped :)
