Two parallel conducting plates with the small gap of 1.0 cm are charged oppositely each other. An electric field of uniform magnitude E=1.00*10^4 N/C pointing from the positively charged plate to the negatively charged plate (+y direction) is produced in the space between those two plates. An electron is released from the negatively charged plate.
a. What is the acceleration of the electron?
b. What is the speed of the electron when it arrives at the positively charged plate?
c. What is the kinetic energy of the electron when it arrives at the at the positively charged plate?
d. How long does it take to travel between the two plates?
A freezer has a coefficient of performance of 2.40. The freezer is to convert 1.98kg of water at 26.0 oC to 1.98kg of ice at -5.00 oC in 1 hour. How much wasted heat is rejected to the room in which the freezer sits
In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 2.50 m/s at an angle of 15.5° above the horizontal. It is released 0.73 m above the floor. What horizontal distance does the ball cover ..
A ball thrown upward returns to the same level after 4s in the air. How long would that ball take to reach the same level
How would you describe why we have different atmospheric pressure on different level (height) of earth's atmosphere in molecular level (molecular behaviour and what causes such behaviour).
