The amount of charge a capacitor can store per volt of potential difference is called the capacitance of the capacitor.
<h3>What is the capacitance?</h3>
The capacitance has to do with the amount of charge that is stored by a capacitor. We know that a capacitor is a device that can be used to store electric charges. We have in it, two capacitors separated by a dielectric material.
Hence, the amount of charge a capacitor can store per volt of potential difference is called the capacitance of the capacitor.

Answer:
3.5434 eV
Explanation:
For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,
E = 
Putting the values we get
E = 
=1.063 x 10⁻²¹ J
= .0066 eV.
Energy of¹light in terms of eV
= 1244 / 350 = 3.55 eV.
Work function = 3.55 - 0.0066 = 3.5434 eV.
You fallow the steps to figure out the complete answer of the question.
Answer:
W = M g weight of ball
T cos θ = W balancing vertical forces
T sin θ = F balancing horizontal forces
tan θ = F / W dividing equations
F = W tan θ when θ equals zero F equals zero
Answer:
Explanation:
Since there is no friction angular momentum is conserved. The formula for angular momentum thet will be useful in this case is 
. If we call 1 the situation when the student is at the rim and 2 the situation when the student is at 
from the center, then we have:
Or:
And we want to calculate:
The total moment of inertia will be the sum of the moment of intertia of the disk of mass 
and radius 
, which is 
, and the moment of intertia of the student of mass 
at position 
(which will be 
or ) will be 
, so we will have:
or:
which for our values is:
