Answer:
puck decelerates due to the kinetic frictional force μk mg
Explanation:
given data
total distance = 12 m
coefficient of kinetic friction = 0.28
solution
we will apply equation of motion that is
v² - u² = 2 × a × s ................1
we know acceleration will be
a = 
Then we have
Force = mass × acceleration .................2
m × = -μk mg
The puck decelerates due to the kinetic frictional force μk mg
and frictional force is negative as it opposes the motion.
so we get initial velocity of the puck which is strike.

<span>The correct answer is: Oxygen
Explanation:
In order to function properly (movement etc.) during exercise, muscles require oxygen. During exercise, the depth as well as the rate of breathing increase, which in turn increases the amount of oxygen inhaled. In order to expand and contract lungs and for other bodily movements, muscles require oxygen, and for that, more oxygen is carried in the blood to muscles. Hence, the correct answer is Oxygen.</span>
A secondary atmosphere<span> is an </span>atmosphere<span> of a </span>planet<span> that did not form by </span>accretion<span> during the formation of the planet's </span>star<span>. A secondary atmosphere instead forms from internal </span>volcanic<span> activity, or by accumulation of material from </span>comet<span> impacts. It is characteristic of </span>terrestrial planets<span>, which includes the other terrestrial planets in the </span>Solar System<span>: </span>Mercury<span>, </span>Venus<span>, and </span>Mars<span>. Secondary atmospheres are relatively thin compared to </span>primary atmospheres<span> like </span>Jupiter's.<span> Further processing of a secondary atmosphere, for example by the processes of </span>biological life<span>, can produce a </span>tertiary atmosphere<span>, such as that of </span>Earth<span>.</span>
