Answer:
except ii and iii
Explanation:
The angle of reflection is the angle to the normal the white rays strikes the water surface and it is the incidence angle. Since the white light is moving from less dense medium to a denser medium or a medium with a higher refractive index; the angle of refraction will be less than 30 degrees. Total internal reflection cannot occur because the white light is traveling from a less dense medium to a denser medium.
B, larceny because that's theft of personal property.
Answer:1). Distance of far point x=0.9m
Therefore, since the image is virtual
-f=-x = -0.9m
Power of the concave lenses = 1/f = 1/-0.9
= -1.11D
2 ) near point is 21cm = 0.21m
Power = 4-1/near point
= 4/0.21
= 14.2D.
Temperature rise will be there in cylinder B more than in cylinder A because of internal energy.
what is internal energy?
The sum of the kinetic and chemical potential energies of all the particles in the system is the internal energy. Particles accelerate and pick up kinetic energy when energy is applied to increase the temperature.
Briefing:
Cylinder A uses the heat it absorbs to both work while expanding and to increase internal energy (or temperature).
While cylinder B solely uses the heat it absorbs to increase its internal energy
As a result, cylinder B's temperature rise is greater than cylinder A's.
