How far will an electron travelling at 200,000 km/s travel in 12 ns?

Distance = Speed × Time Given: Speed = 200,000,000 meters/s Time = 12 × 10^-9 seconds Now, calculate the distance: Distance = 200,000,000 meters/s × 12 × 10^-9 s To multiply these values correctly, you can first perform the multiplication of the numerical parts and then deal with the powers of 10: Distance = (200,000,000 × 12) × 10^(-9) meters Distance = 2,400,000,000 × 10^(-9) meters Now, simplify the result: Distance = 2.4 meters So, the distance an electron will travel in 12 nanoseconds at a speed of 200,000,000 meters per second is 2.4 meters.
