A 5.56 V battery is connected across two large parallel metal plates that are separated by 4.57E-3 m of vacuum. A proton is released from rest at the positive plate. If the only force on the proton is the electric force exerted by the electric field of the plates, what is the kinetic energy of the proton as it reaches the negative plate (in Joule)

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)
