the equation used to calculate the weight of an object on a plant is f = ma. "f" is the force measures in newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
the first step is making objective observations.
they have to be based on a certain event and can be confirmed by others if it is right or not.
microwaves are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. microwaves heat food like the sun heats your face—by radiation.
