Your hypothesis can be that the group with calculators would finish faster than the group without calculators.
Answer:
The sun produces energy by Nuclear Fusion.
Explanation:
Turns Hydrogen atoms to Helium which is then known as Nuclear Fusion.
Well I know that ernest rutherford did the gold foil experiment where he fired alpha particles at gold foil. This experiment founded the nucleus but I don't know if the current model of the atom is based on this.
Cathode ray tube experiments sounds like its to do with electrolysis so i dont think it can be that.
The circular motion is usually analyzed by using the polar coordinates
. The transformation between Cartesian coordinates (x,y) and polar coordinates is
where basically
corresponds to the distance between the object and the origin of the axes (0,0) while
is the angle which gives the direction.
The main advantage of the polar coordinates is that when analyzing a circular motion, the radius
is a constant, since the object is moving on a circular path, and so it is possible to describe the motion of the object by specifying only the angle
.
