The common value for the speed of light in a vacuum is:
1 answer:
The common value for “Speed of light in vacuum” is metre per second.
Answer: Option b
<u>Solution: </u>
Speed of light can be defined as the speed with which light waves propagate in different medium. In vacuum, speed of light is 186,282 miles per second or 299,792 km/s which is rounded off as .
“Speed of light in vacuum” is a universal constant and usually represented by ‘c’. Light waves travels at a speed of metre per second in vacuum.

Heya!!
For calculate aceleration, let's applicate second law of Newton:
⇒ Being:
→ F = Force = 12 N
→ m = Mass = 3 kg
→ a = aceleration = ?
Lets replace according formula and leave the "a" alone:
Result:
The aceleration of the object is of <u>4 m/s²</u>
The electrostatic force between two charges is given by
where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the charges
In our problem,
Therefore the electrostatic force is
