Watt = voltage x ampere
750 = 220 x ampere
Ampere = 750 / 220
Resistance = voltage / ampere
= 220^2 / 750
Answer:
Explanation:
If angle of incidence and angle of refraction be i and r respectively ,
sini / sinr = μ ( refractive index )
sin r = sin i / μ
If angle of incidence i be constant and medium becomes denser that means μ becomes higher in value , the value of sin r will be low ( because of increase in value of denominator )
As sin r decreases , r also decreases also.
Hence when medium becomes denser , angle of refraction becomes less .
<span>CorrectThe direction of the electric field stays the same regardless of the sign of the charges that are free to move in theconductor.Mathematically, you can see that this must be true since the expression you derived for the electric field isindependent of .Physically, this is because the force due to the magnetic field changes sign as well and causes positive charges tomove in the direction (as opposed to pushing negative charges in the direction). Therefore the result isalways the same: positive charges on the side and negative charges on the side. Because the electric fieldgoes from positive to negative charges will always point in the direction (given the original directions of</span>
I don't think I want to go into a lot of detail here, but the answer is
"sometimes true and sometimes false". I believe it depends on the
original difference between XC and XL, before XC began to change.
