On a sunny day, you and a friend are relaxing on the grass at a park. your find says that the sun shines while light on the park, the green light is absorbed into the grass, which is why it appears green. do you agree with your friend? explain why or why not?

i do agree to my friend

Explanation:

White light is absorbed by the callours that are not white. if it was white it would of been reflected. The light also helps us to see the object i.e the grass as the light is shining on it.

i hope your happy :)

I don't agree with my friend

Explanation:

We see grass green because the green light is reflected by the grass and it absorbs all other light. In the particular case of plants, this is caused by chloroplasts, which uses all wavelength of light except green to perform photosynthesis, and then green is predominately reflected.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
