Anthony is experimenting with how the amount of air inside a basketball affects how high it bounces. He uses logical reasoning to conclude that he should drop each ball from the same height. Why is this important?

A. Dropping the balls from the same height is less fun.

B. Dropping the balls from different heights would introduce error.

C. Dropping the balls from different heights would take longer.

D. Dropping the balls from the same height will create more data for
the experiment.

It’s either B or D I need help it’s due tonight

Apossible explanation for a set of facts that can be tested by further investigation is called

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
