Answer:
(a) Surface charge density is the charge per unit area.
(b)
(c)
Explanation:
(a) Surface charge density is the charge per unit area. The area of the square plate can be calculated by its side length.
Half of the total charge is distributed on one side and the other is distributed on the other side.
Therefore, surface charge density on each face of the plate is
(b) To find the electric field just above the plate, Gauss' Law can be used. Normally, Gauss' Law can only be used in infinite sheet (considering the flat surfaces), but just above the surface can be considered that the distance from the surface is much much smaller than the length of the plate (x << l).
In order to apply Gauss' Law, we have to draw an imaginary cylinder with radius r. The cylinder has to stay perpendicular to the plane.
The direction of the electric field is in the upwards direction.
(c) The magnitude of the electric field is the same as that of upper side. Only the direction is reversed, downward direction.
Answer:
Explanation:
As we know that the centripetal force is given as
now we will have to find the rate of change in force with respect to its radial distance
so we have
so we have
m = 1000 kg
v = 13.89 m/s
r = 200 m
now we have
The Vapor Pressure of water increases by 5.1%. when the temperature increases by 1 °c from 14°c to 15°c.
The vapor pressure of a liquid, sometimes referred to as the equilibrium pressure of a vapor above its liquid, is the pressure of the vapor produced by the evaporation of a fluid (or solid) over a sample of the liquid (or solid) in such a closed container (or solid).
Vapor pressure is the term for the force that is produced as liquids evaporate. Three factors commonly have an effect on a vapor press: surface area, intermolecular forces, and temperature. The vapor pressures of molecules change with temperature.

-- The greatest common factor of 2525 and 3535 is 5.
-- So the greatest possible number of teams is 5.
-- Each of the five teams will have 505 girls and 707 boys.
-- Rafaela is a superwoman ! She's handling more kids in that class than there were in my whole high school !
She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.
But come on ! She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only' 1,212 students on it !
And these are all in one class ! If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !
Or maybe not. I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.
And possibly several OTHER schools in town too.
A) 6000J
the formula will fit in, once you know the formula you are good to answer.
