Question: A police radar's effective range is 0.80 km, and your radar detector's range is 2.1 km. You're going 120km/h in a 68km/h zone when the radar detector beeps.
Part A: At what rate must you negatively accelerate to avoid a speeding ticket?
I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
An electron is accelerated through an electric potential of 255 V, Find the radius in cm of the subsequent circular path for this electron
