Answer:
13,140N
Explanation:
Centripetal force (CF) = mv^2/r
Mass(m) = 1.46×10^3, velocity (v) = 15m/s, radius (r) = 25m
CF = (1.46×10^3 × 15^2)/25 = 328500/25 = 13,140N
Answer:
a.)
b.) 5 blocks
Explanation:
Let's find the volume of the metal block:
Now, let's find the volume of the smaller blocks:
So, one small block has a volume of 8cm. If the volume of the larger block is 40cm, we can fit a total of 5 smaller blocks into the larger block, meaning it will make up the same volume.
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.
