Two 1.2m nonconducting wires meet at a right angle. One segment carries 2.5µC of charge distributed uniformly along its length, and the other carries −2.5µC distributed
uniformly along it, as shown in Fig. P21.99. (a) Find the magnitude and direction of
the electric field these wires produce at point P, which is 60.0cm from each wire. (b) If
an electron is released at P, what are the magnitude and direction of the net force that
these wires exert on it?

answer: question1

1,000 tons

question2

question 3

store d

step-by-step explanation:

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope 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.
