la separación mecánica de un sólido de grano grueso, insoluble, en un líquido; consiste en verter cuidadosamente el líquido, después de que se ha sedimentado el sólido. Por este proceso se separan dos líquidos miscibles, de diferente densidad, por ejemplola separación de un sólido disuelto en un líquido, por calentamiento, hasta que hierve y se transforma en vapor. Como no todas las sustancias se evaporan con la misma rapidez, el sólido disuelto se obtiene en forma pura, agua y aceite.
-- A motor and a generator both do a transformation between electrical energy and some other form of energy, but they do it in opposite directions.
-- A motor takes electrical energy and transforms it into mechanical energy, which can then be used to run mechanical things like cars or wheat grinders.
-- A generator takes mechanical energy ... like from a steam turbine or a windmill or a water wheel ... and transforms it into electrical energy, which can then be shipped over long distances through wires, and used to run motors or other electrical things.
Answer:
34.4Joules
Explanation:
Complete question
a man is trying to pull a box a distance of 3 m with a force of 20 N that makes a 35º with the horizontal. Find the workdone
Work done = Fdsin theta
Force F = 20N
distance d = 3m
theta = 35 degrees
Substitute
Workdone = 20(3)sin 35
Workdone = 60sin35
Workdone = 34.4Joules
Hence the workdone by the man is 34.4Joules

answer: a. Jupiter
The data are recorded incorrectly. All of Lucy's data is correct, she just needs to convert her measurements from centimeters to millimeters.
