<span>F = m.a
= mass x acceleration
So,
a = F / m
Where,
F is coulomb repulsion.
k q q / r^2
with,
k = 9 x 10^9 in SI units (q in C and r in m)
Hence,

Answer:
D. Carbon.
Explanation:
Carbon can be mixed with Many things. for example, YOU are mostly made out of carbon. Other things include furniture, clothing, plastics, charcoal, pencil led, diamonds, and gas.
The air pressure inside the can is lower compared to that of outside air pressure.
Explanation:
- In general, the air pressure of an already opened can will be the same as the outside pressure.
- Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
- If the can opens, air inside the can push the top and escapes to the outside.
- This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.
The ionic compound is CaSO4
