A nozzle with a radius of 0.26 cm is attached to a garden hose with a radius of 0.91 cm that is pointed straight up. The flow rate through the hose and nozzle is 0.65 l/s.
a) Increase the radius of the nozzle to 0.3 cm and the radius of the hose to 1.0 cm to increase the flow rate
b) Decrease the radius of the nozzle to 0.2 cm and the radius of the hose to 0.8 cm to decrease the flow rate
c) Adjust the angle of the garden hose to a 45-degree angle to change the direction of the flow
d) Use a higher pressure water source to increase the flow rate through the hose and nozzle
