The strength of the electric field 0.5 m from a 6 µc charge is positive n/c. (use k = 8.99 × 109 n• and round answer to the nearest whole number.)

Explanation:

The strength of the electric field produced by the single charge is given by

where

is the Coulomb's constant

is the charge

is the distance from the charge at which we want to calculate the field strength

Substituting the numbers into the equation, we find

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
