Ineed on my physics work and show me how you got it

Answer

It increases to B, then it decreases.

When the stone thrown upwards, it moves vertically upwards to a maximum height then is starts to come down. Due to gravitational force, the velocity of the stone projected upwards decreases but when coming down wards is increases.

The trajectory shown in the diagrams represents an example of an object projected upwards.

We can then says that the vertical component increases from A to B, then it decreases to C.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
