Check my physics question's answer asap ? you measure the mass of a 0.500 kg (500 g) standard on your balance four times. the following measurements result: 498 g, 501 g, 499 g, 500. which of the following best describes your balance? 1) precise and accurate < i think it is this one? 2) not precise and not accurate 3) precise but not accurate 4) not precise but accurate

1 i just took the quiz and got a 100

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
