Answer:
F
Explanation:
Newton's Third Law (Law of Action-Reaction) states:
Every action has an equal and opposite reaction and it occurs between two objects
In this scenario, the action would be the skater pushing off of the wall, therefore the reaction would be the wall pushing off of the skater since the two objects that are interacting are the wall and the skater.
Answer:
its surface temperature = 54.84 ° C
Explanation:
The density of aluminium 
= 2700 kg/m ³
Heat capacity 
= 897 J/Kg.K
radius of the sphere (r) = 0.081029 m
= 25 °C
= 124.978 °C
time (t) = 767.276 s
Using the formula :
where.
Replacing our values ;we have:
T ≅ 54.84 ° C
Therefore, its surface temperature = 54.84 ° C
Answer:
I would say since it is still water the stream flow is 0km/h. Especially because he needs the same time upstream as He does down stream.
