Answer:

4.  D and E

Explanation:

As we know that the relation between phase difference and path difference is given below

\delta \phi = \frac{2\pi}{\lambda} \delta x

now we have to find the distance of two points which are out of phase by 90 degree

so here we will have

\frac{\pi}{2} = \frac{2\pi}{\lambda} \delta x

so from above we have

\delta x = \frac{\lambda}{4}

so the distance between the points will be 1/4 times of wavelength

so here correct answer is

4. D and E

27 degrees to kelvin, 20 dg to milligrams, and 3 to decimeters.
Gala2k [10]
K = C + 273, so 27°C = 27+273 = 300 K

1 dg = 100 mg, so 20 dg = 20×100 = 2,000 mg

84. Three resitors each of value 30 respectively are connected in a parallel
kati45 [8]

Answer:

each resistor draws 1/3 of an amp or 0.33333 amps

Explanation:

V = I * R

V = 10 volts

R = 30 ohms

10 = I * 30       Divide by 30

10/30 = I

I = 0.33333
