In the diagram, 91 = +3.25*10^-9 C. What is the potential difference when
you go from point B to point A?
Include the correct sign, + or - .
91
A

0.150 m-% 0.250 m –
(Hint: Does V go up or down when you go from B
to A? What is the distance from q1 to B?)
(Unit = V)

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
