A150 g egg is dropped from 3.0 meters. the egg is
moving at 4.4 m/s right before it hits the ground the egg
comes to a stop in 0.072 seconds.
what is the magnitude of force that the ground exerted on
the egg?
0.66 n
9.2n
13n
180 n

9.2 N

Explanation:

F = ma

F = m Δv / Δt

F = (0.150 kg) (4.4 m/s − 0 m/s) / 0.072 s

F = 9.2 N

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

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.
