Niagara Falls is 51 meters high. If you dropped a ball off the ledge, how much time would it take it to hit the water? PLEASE SHOW WORK. WILL MARK BRAINLIEST

Who was the first scientist to measure speed as distance over time?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
