Density.
an electroscope is used to determine whether an object is charged or not. However, it will not tell if the object is positively or negatively charged.
no,because your an idiot I'll tell you oh nevermind haha
. . .point of reference. For example, one can tell whether a planet is moving according to its position in relation to a star.
yes. because by light now a days we are giving laser tratements in kidneas etc by this way i can tell light can push a solid.
A rainbow appears
how can you tell if an object is reflecting blue light from a star
density
Density.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
It really depends on the size, for normal sized keep it not too light but not too heavy you can tell by doing this : spin your bey if it hits an object and stops spinning in one hit it is too light if it wobbles too much it is too heavy if you get it right it will spin for 1 minute like mine
your finger can tell when an object is hot or clod because when a stimulus (the object) touches your skin, receptors transmit it to the brain and your brain sends a reflex reaction to let go
