Answer:
A. it will move faster than the large object was moving initially
Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe



= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION


solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation



r = 0.87 cm
d = 2*0.87 = 1.75 cm
Well over time the temperature of the water increase causeing its moleclues to move alot which causes it's state change to a gas this is who we have rain.
