Answer:
See explanation
Explanation:
Solution:-
- light reflected through calcite crystals difference occurs due to the polarity of the light passing through the crystal. Daylight is composed of light vibrating in all planes, whereas reflected light is often restricted to a single plane that is parallel to the surface from which the light is reflected.
- Light that is reflected from the flat surface of a dielectric (or insulating) material is often partially polarized, with the electric vectors of the reflected light vibrating in a plane that is parallel to the surface of the material.
- light waves that have the electric field vectors parallel to the surface are reflected to a greater degree than those with different orientations.
By Newton's 2nd law, m*a=sum_of_forces where m is the mass and a the acceleration. Here there are two forces in opposed directions.
Thus 5*a=40-8=32 therefore a=32/5=6.4m^s/2
630.15 kelvin, 312.05 kelvin
Answer:
q = 1.815 \times 10^{-8} C
Charge on one plate is positive in nature and on the other plate it is negative in nature.
Explanation:
E = 8.20 x 10^5 V/m, A = 25 cm^2, d = 22.45 mm
According to the Gauss's theorem in electrostatics
The electric field between the two plates
Charge, q = surface charge density x area
q = 1.815 \times 10^{-8} C
Three different units of energy is
1. Joule: is is SI unit of measuring thermal energy or heat
2. Calorie: this system of energy is used when we take CGS system of mass and specific heat capacity
3. BTU: this system is known as british thermal unit which is used in measuring engineering calculations
