No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).

Why does light refract when it passes from air into a glass slab?
Because glass slab is optically denser than air.
How much do paving slabs weigh approximately?
A standard paving slab will weigh approximately 70KG, which is about 154 pounds. Of course, it varies in weight according to the actual size of the slab, but that is what the average standard slab will weigh.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
How should a ray of light be incident on a glass slab so that it comes out from the opposite side of slab without being displaced?
The question is phrased very poorly, as the photon is by definition displaced after traveling through the slab. If you meant "deflected", however, it must be normal.
What is the angle between incident ray of light and emergent ray of light when incident ray of light falls obliquely?
The angle between the incident ray and emergent ray is called the angle of - DeviationIt depends on the refractive index of the glass slab, the material the light is traveling through before hitting the slab as well as the angle it hits the slab at.Snell's law:The refractive index of the medium the light is traveling out of - times - sin for the angle between the ray of light and the normal of the surface = the refractive index of the medium the light is traveling into - times - sin for the angle between the ray of light and the normal of the surface on the other side.n1 * sin(angle1) = n2 * sin(angle2)Where:n1 = Refractive index of the material the light is exiting.sin(angle1) = Sin for the angle at which the light hits the surface of the glass slab. This angle is measured by drawing a line from the point on the glass slab that the light hits the surface perpendicular to the surface, that is to say at a 90 degree angle against the surface. You then measure the angle between this new line and the line of the ray of light.n2 = Refractive index of the material the light is enteringsin(angle2) = Sin for the angle at which the light leaves the edge of the glass slab.Illustration:http://www.math.ubc.ca/~cass/courses/m309-01a/chu/Fundamentals/snell01.gif
An air-filled parallel-plate capacitor is connected to a battery and allowed to charge up Now a slab of dielectric material is placed between the plates of the capacitor while the capacitor is still?
the charge on the capacitor had increased.
How much weight 4inches slab hold per square foot?
The answer will depend on 4 inch slab of what material!
Why crank is given in concrete slab?
Cranks are given in the slab according to the change in the BM from negative to positive exactly before column and also to maintian the thickness of slab.
How can you calculate shuttering material?
Slab area multiply 1.4 times.
What happens to the charge of a capacitor when a dielectric slab is fit in it?
Changing the dielectric causes the capacitance to change.
How can you lift a concrete porch slab 6 inches?
Certain companies exist that have pumping equipment that will hydraulically lift the slab to the desired height. It's called slab jacking. Other than that, it would be best to tear out and replace the existing slab, using an adequate base material to prevent future settling.
What causes the outward pressure that balances the inward pull of gravity in a star?
This is straight out of my Astronomy textbook from the last semester: "… imagine a slab of material in the solar interior. In equilibrium, the slab on average will move neither up nor down. (In, fact there are upward and downward motions of material inside the Sun, but these motions average out.) Equilibrium is maintained by a balance of among three forces that act on this slab: 1 The downward pressure of the layers of solar material about the slab. 2 The upward pressure of the hot gasses beneath the slab 3 The slab's weight - that is, the downward gravitational pull it feels from the rest of the sun. The pressure from below must balance both the slab's weight and the pressure from above. Hence, the pressure below the slab must be greater that that above the slab. In other words, pressure has to increase with increasing depth. For the same reason, pressure increases as you dive deeper into the ocean or as you move toward lower altitudes in our atmosphere." So I guess the answer you are looking for is "the inward pull of gravity is balanced out by the pressure of hot rising gasses."
What are Advantage and disadvantage of In-situ concrete slab?
disadvantage: - require more time to construct compare to precast concrete slab -more on-site labor required - require formwork advantage: -most commonly use -do not require storage for material (e.g. precast concrete slab need place to store)
What difference suspended concrete slab between unsuspended concrete slab?
Supended slab are slab not sit on the ground directlySuspended slab is a slab supported by beams.
Is a divergent a slab-push a slab-pull?
convergent boundary
