Aparallel-plate capacitor with a 4.9 mm plate separation is charged to 57 v . part a with what kinetic energy, in ev, must a proton be launched from the negative plate if it is just barely able to reach the positive plate?

57 eV

Explanation:

= separation between the plates = 4.9 mm = 0.0049 m

= Potential difference between the plates = 57 Volts

= magnitude of charge on proton = 1 e

= Kinetic energy of the proton

Using conservation of energy

Kinetic energy lost = Electric potential energy gained

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
