The electrical breakdown of an insulator occurs when an electric field becomes large enough to ionize the insulator, allowing electrical current to flow; lightning is an example of the electrical breakdown of air. The electrical breakdown of air occurs when the electric field reaches about 3 × 10 6 N/C 3×106 N/C . Estimate the magnitude of the total static charge on your body q body qbody when you generate a static spark with your fingertip when getting out of your car. Assume a spark gap of 1 mm 1 mm .

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.

Which property is expressed in distance units? o a. period o b. wavelength o c. speed o d. frequency
