A. four equal particles with positive charge q = 14.418x10-19 c and mass m = 81.99x10-31 kg are initially held at the four corners of a square of side l = 0.07 m. what is the total electric potential at the center of the square? (in v)

b. if these particles are released simultaneously, what will be their speed when they have separated by a very large distance? you may neglect gravitational effects. in (m/s)

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
