The statement that is true of cooling down after physical activity is that you should cool down for about 5 to 10 minutes after being physically active.
You get a lot of detailed information. hope this helped :)
Explanation:
Internal energy = heat + work
U = Q + W
Since there's no change in volume (rigid walls), W = 0.
U = Q
U = n Cᵥ ΔT
U = (4.0 mol) (2.5 × 8.314 J/mol/K) (354 C − 17 C)
U = 28,000 J
I’m not too sure but I think it’s 8,91 m/s2
Yes. If a downward force is created, it will be felt at the end of the rope as well.
