In science, bob learns that the energy of a wave is directly proportional to the square of the waves amplitude. if the energy of a wave is 4 j, what should he predict as the amplitude of the wave? a) 1 j b) 2 j c) 4 j d) 8 j

B)2 J

Explanation:

2 J

Since E ∝ amplitude2 then as the amplitude is doubled the energy is quardrupled.

Plugging in to check

amplitude2=E

amplitude2=4

amplitude2

=

4

amplitude=

4

amplitude=2

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
