Answer:
Explanation:
The electric field inside a parallel plate capacitor is
where A is the area of one of the plates, and Q is the charge on the capacitor.
The electric force on the electron is
where q is the charge of the electron.
By definition the capacitance of the capacitor is given by
Plugging this identity into the force equation above gives
The work done by this force is equal to change in kinetic energy.
W = Fx = (30q)(0.05) = 1.5q = K
The charge of the electron is
Therefore, the kinetic energy is
Answer:
La verdad no entendi bien pero igual esta muy bien, Escoge lo que sientas en el corazón
Explanation:
Haz lo que sientas eso es lo mejor
Microwave~Inside the strong metal box, there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves. ... Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up
Radio~ The radio waves transmitted and received by wireless computer networks are at much higher frequencies than those used by other device
B is negatively charged.
The electrons outnumber the protons, showing that its charge is negative.
However, on the rest of the hands, the number of electrons are either equal to (making the charge neutral) or less than (making the charge positive) the number of protons.
Hope this helped!
