The portion of the flux leaves the curved surface of the cylinder is 60%.
<h3 /><h3>What are electrons?</h3>
The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the total flux leaving the cylinder.
If 20% of the flux leave from one end, then another 20% will leave from another end.
So, the net flux through curved surface is
100 -20 -20 = 60%
Thus, the total flux leaves the curved surface of the cylinder is 60%

Answer:
The tangential speed at Livermore is approximately 284.001 meters per second.
Explanation:
Let suppose that the Earth rotates at constant speed, the tangential speed (
), measured in meters per second, at Livermore (37.6819º N, 121º W) is determined by the following expression:
(1)
Where:
- Rotation time, measured in seconds.
- Radius of the Earth, measured in meters.
- Latitude of the city above the Equator, measured in sexagesimal degrees.
If we know that 
, 
and 
, then the tangential speed at Livermore is:
The tangential speed at Livermore is approximately 284.001 meters per second.
Answer:
This question is incomplete
Explanation:
The question is incomplete because of the absence of options.
However, <u>the force that makes a paint cling to a wall is adhesive force</u>. Adhesive force is the force between two unlike substances like a liquid clinging to a solid surface.
The force between adhesives or glue is also the force that makes them sticky. <u>This force is referred to as cohesive force</u>. This is a force found in between similar molecules (unlike adhesive force found between dissimilar molecules).
<u>The force that makes wax to stick to a car is electromagnetic force</u>. This is a force between charged particles; whether they appear to be moving or not. These particles of opposite charges come together to form a neutral force. In this case, charged atoms of the car and the wax come together (which causes what we see as the wax sticking to the car).
Answer:
b. Decreases
Explanation:
The total resistance of a series circuit is equal to the sum of the individual resistances:
(1)
Therefore, as we add more lamps, the total resistance increases (because we add more positive tems in the sum in eq.(1).
The current in a circuit is given by Ohm's law:
where V is the voltage provided by the power source and 
is the total resistance. We notice that the current, I, is inversely proportional to the total resistance: therefore, when more lamps are added to the series circuit, the total resistance increases, and therefore the current in the circuit decreases.
