Energy cannot be created nor be destroyed
Tectonic plates is the unscrambled phrase in that jumble.
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



The corresponding electric field strength is 0.05 V/m
KE = PE
1/2 m • v^2 = mgh
1/2 • v^2 = gh
V^2/2 = gh
2 • (v^2/2) = 2 • (gh)
V^2 = 2gh
V = sq root (2gh).
KE = (1/2) (mass) (speed)²
KE = (1/2) (0.5 kg) (10 m/s)²
KE = (1/2) (0.5 kg) (100 m²/s²)
KE = (0.25 kg) (100 m²/s²)
KE = 25 Joules
