a super man I sitting on a tree 98m high with a he has rescued from a claws of a tiger. unfortunately the child shift and falls with an initial velocity of 0m/s supposed reached what was happened 2 second later and flow to catch the child at a speed of 39.2m/s find the time super man will fly before catching the child, and the distance super man fly to catch the child

Me to solve all the questions on the sheet attached

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
