iren [92.7K]

Answer:

0.05 V/m

Explanation:

V = Potential difference that is possible for the dolphin to detect = 0.5 mV

d = Distance between electrodes = 1 cm

Electric field strength is given by

E=\dfrac{V}{d}

\Rightarrow E=\dfrac{0.5\times 10^{-3}}{1\times 10^{-2}}

\Rightarrow E=0.05\ V/m

The corresponding electric field strength is 0.05 V/m

(10. Five pupils have a mean mass of 51 kg.
sveticcg [70]

Explanation:

If the fourth pupil has a mass of x, and the fifth pupil has a mass of x+5, then the mean mass is:

51 = (49 + 53 + 52 + x + x+5) / 5

255 = 159 + 2x

x = 48

x + 5 = 53

The fourth pupil has a mass of 48 kg.

The fifth pupil has a mass of 53 kg.
