Answer:
Third Law of motion. (answer C)
Explanation:
This is an example of Newton's Third Law of motion which normally translates into Action/Reaction. That is : the expelled air exerts a force in the direction opposite to that of the motion of the air that goes out. It is the same as propulsion in a rocket.
Chlorophyll: green
Anthocyanins: red
Carotene: orange.
Sorry I couldn’t find the 4th one
The radioactive decay obeys first order kinetics
the rate law expression for radioactive decay is
![ln\frac{[A_{0}]}{[A_{t}]}=kt](https://tex.z-dn.net/?f=ln%5Cfrac%7B%5BA_%7B0%7D%5D%7D%7B%5BA_%7Bt%7D%5D%7D%3Dkt)
Where
A0 = initial concentration
At = concentration after time "t"
t = time
k = rate constant
For first order reaction the relation between rate constant and half life is:
Let us calculate k
k = 0.693 / 72 = 0.009625 years⁻¹
Given
At = 0.25 A0
time = 144 years
So after 144 years the sample contains 25% parent isotope and 75% daughter isotopes**
Simply two half lives
Answer:It would never stop until something hit the ball, to slow it down.
Explanation:
This is so because there is no gravitational pull in space.
The answer is C. Only metallic alloys are malleable and ductile. The other descriptions can apply to all 3 answers
