Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval of 3.20Γ10-6 s. 1-find the magnitude of the electric field. use 1.60Γ10-19c for the magnitude of the charge on an electron and 1.67Γ10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate

9. an object is moved from the outdoors, which is at a temperature of 100 ΒΊf, to a room at a temperature of 70 ΒΊ f. what happens to the object when itβs placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
