Calvert likes to paddle around in his canoe. one day it sprung a leak and started to fill with water. luckily, calvert was able to swim to shore, but the boat sank.
why did the boat sink?
a)the hole in the boat increased the density of the boat, so it was not able to float.
b)the weight of the water was greater than the buoyant force on the boat.
c)the boat was able to displace less water, so it was not able to float.

b.a device that inputs heat into a cool object

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.
