Answer:
0.06 kg
Explanation:
Given data:
Mass of frisbee = ?
Velocity of frisbee = 11 m/s
Energy of frisbee = 3.6 j
Solution:
K.E = 1/2 mv²
Now we will put the values in this formula.
3.6 J = 1/2 m(11m/s)²
3.6 j = 0.5 ×121m²/s² × m
3.6 j = 60.5 m²/s² × m
m = 3.6 j/60.5 m²/s²
m= 0.06 j.m⁻².s²
j = Kg.m².s⁻²
m= 0.06 Kg.m².s⁻² .m⁻².s²
m = 0.06 kg
Answer:
C. freezing
Explanation:
Point B is right at the border between a solid and a liquid so you can have two physical changes:
a) solid is <u>meting</u> to transform into a liquid
or
b) liquid is <u>freezing</u> to transform into a solid (C)
If you are on the border between a solid and a gas you have the following physical changes:
solid to gas - sublimation
gas to solid - deposition
If you are on the border between a liquid and a gas you have the following physical changes:
liquid to gas - boiling
gas to liquid - condensation

From looking over the graph, I would say the second option, "Marsha earns the most money per item sold because her line increases at a faster rate than Dreya's." Hope this helps, have a BLESSED day! :-)
