Most atoms are electrically because the number of protons equals the number of electrons. Atoms with an electric charge become charged by gaining or losing . When this charge becomes built up on an object, we call that build up .

Ajogger accelerates from rest to 4.86 m/s in 2.43 s. a car accelerates from 20.6 to 32.7 m/s also in 2.43 s. (a) find the magnitude of the acceleration of the jogger. (b) determine the magnitude of the acceleration of the car. (c) how much further does the car travel than the jogger during the 2.43 s?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Which is not true of alpha radiation? o a. it increases the number of protons. o b. it has a positive charge. o c. it causes transmutation. o d. it is heaviest of the three types
