Guiana dolphins are one of the few mammals able to detect electric fields. in a test of sensitivity, a dolphin was exposed to the electric field of charged electrodes. the electric field was measured by detecting the potential difference between two electrodes located 1.0 cm apart along the field lines. the dolphin could reliably detect a field that produced a potential difference of 0.50 mv. what is the corresponding electric field strength?

0.05 V/m

Explanation:

For a uniform electric field, electric field strength and potential difference are related by

where

E is the electric field strength

is the potential difference

d is the distance between the two points

Here we have

So, the electric field strength is

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.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
