Answer: v = 
Explanation: q = magnitude of electronic charge = 
mass of an electronic charge = 
V= potential difference = 4V
v = velocity of electron
by using the work- energy theorem which states that the kinetic energy of the the electron must equal the work done use in accelerating the electron.
kinetic energy = 
, potential energy = qV
hence, 
Answer:
true
Explanation:
a wheelbarrow has its load situated between the fulcrum and the force the wheel Barrow is 2nd class because of its resistance between the force and the axis
Well, the acceleration is the difference of speeds divided by the time period.
.
One rev/s is
, so our final result is
.
Currently, many researchers are still working to find them.
Currently , its only theorized and they should be based on the quantum and particle theory
hope this helps
