Given
Radius of bicycle wheel 
Initial angular velocity 
It rotates 3 revolution in 5 s therefore

using 
where 



Total acceleration of any point will be a vector sum of tangential acceleration and centripetal acceleration




Tangential acceleration 





When two bodies collide with each other in the absence of an external force, then the total final momentum of the bodies is equal to their total initial momentum.
<u>Answer:</u>
<em>1. A NaCl solution with a concentration of 50g/100mL of water at 40°C:</em> The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.
<em>2. A sugar solution with a concentration of 200g/100mL of water at 40°C: </em>The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.
