Answer:
Option B
Explanation:
Looking at the 3 galvanometer readings given above, for galvanometer A, the reading is -2 mA.
For galvanometer B, the reading is 4 mA.
While for galvanometer C, the reading is -5 MA
Thus, option B is correct.
Answer:
let's say you're on a bus going 50 km/hr, you are moving at a velocity of zero relative to the bus. however, relative to the ground you are moving at the same velocity as the bus.

Answer:

Explanation:
Given data:
first case
Distance of electric field from center of sphere is r_1 <R
Electric field at r_1< R

second case
Distance of electric field from centre of sphere is r_1 < 2R
Electric field at r_1< 2R

so, we have

An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile.
Unlike flat spiral galaxies with organization and structure, they are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center.
Answer:
Proof:
|----------(R1)-------------(R2)---------|
Let the resistances be R1 , R2 connected in series. And the potential difference be V ;
We know that :
P1 = V²/R1 ..........(1) and
P2 = V²/R2 ...........(2)
In series combination , the net resistance is the algebraic addition of individual resistance :
R = R1 + R2
=> V²/P = V²/P1 + V²/P2
=> 1/P = 1/P1 + 1/P2
