In a ionic liquid, electric currents are carried by both positive and negative ions. an electric field is set up in a cylinder of cross-sectional area a. positive ions drift to the right with speed v1 and negative charges drift to the left with speed v2. the liquid is neutral so the density of positive and negative charge carriers are both equal to n. the positive ions have charge +e and the negative ions have charge -e. what is the current? (a) i = enavi + enav2 to the right (b) i = enavi + en av2 to the left (c) i = enav1 - enav2 to the right (d) i = enav1- en av2 to the left

c)as speed changes, wavelength and frequency change.

everything changes!

are there options? cause you ain’t. real specific

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
