Explanation:
B. More mass results in less acceleration.
I think it should be option (b)
<span>Velocity, you divide distance/time </span>
The equilibrium temperature of aluminium and water is 33.2°C
We know that specific heat of aluminium is 0.9 J/gm-K, and that of water is 1 J/gm-K
Now we can calculate the equilibrium temperature
(mc∆T)_aluminium=(mc∆T)_water
15.7*0.9*(53.2-T)=32.5*1*(T-24.5)
T=33.2°C
A=mgh
m=300g=0.3kg
g=9,81 m/s^2
h=10m
A=29.43J
