A hot air balloon lifts 50 meters vertically into the air and then comes back down. What are the displacement and distance of the balloon’s flight? The displacement is 100 meters and the distance is zero.
The displacement is 50 meters downward and the distance is 100 meters.
The displacement is zero and the distance is 100 meters
The displacement is 50 meters upward and the distance is 100 meters.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

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 f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
