Worth 30 points! answer ! any question will do, if you choose to answer two then more power to ya, and if you choose to answer all, then hot dang you just earned brainliest. question i how do i distinguish what is science from what is not science? question ii how does the scientific method work? question iii how does the latitude affect the angle of sunlight hitting earth? question iv how does the angle of incoming sunlight effect the amount of energy earth receives? question v what would the climate be like on earth if it was not tilted on it's axis? question vi explain why it is challenging to fly a space craft to mars.

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
