Experiment with the catapult by changing the amount of energy used to pull the spoon down. When you pull down a small amount and release the marshmallow, what happens? Record your observations. When you pull down a large amount and release the marshmallow, what happens?

when The spoon is pulled down with a small amount of energy : short distance travelled by Marsh mallow

When the spoon is pulled down with a higher amount of energy : Long distance travelled by Marshmallow

Explanation:

when The spoon is pulled down with a small amount of energy :

After the release of the spoon  the Marshmallow travels a relatively short distance because the acceleration is < mass of the mass of the Marshmallow

F = ma. hence a = F/m    where a < m

When the spoon is pulled down with a higher amount of energy

After the release of the spoon the marshmallow travels a relatively long distance when compared to the application of small amount of energy

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
