A person runs off a cliff into a lake below. If the person leaves the cliff without a horizontal velocity of 4m/s, how far way from the cliff does he land is the cliff is 17m high?

Any good and bad insulators of thermal energy, hot or cold, and why?

You create a transformer by wrapping wire around an iron nail. The number of turns are: Primary (500); Secondary (2500). The Primary voltage is 3.00 V. The Secondary current is 200 mA.
