Question

1. As a stream of water flows, the cross-sectional area of the stream becomes smaller. If it initially moves with a speed of 1.8 m/s and then the cross-sectional area decreases to one-fourth of the original area, what is the water speed in this narrowed part of the stream?____ m/s

2. (As water falls, its speed increases, due to the acceleration of gravity. If you make a steady stream of water flow from a faucet, you will see that the stream has a distinct boundary, and the stream becomes narrower the farther it falls. You will compare the area of the stream at two locations: at the opening of the faucet, and a short distance downstream.) At the opening of the faucet, the water emerges at a speed of 6.0 m/s. At a short distance downstream, the speed increases to 6 m/s. The ratio of the cross-sectional areas of the stream (calculated as the area downstream, divided by area at the opening) is? ____

Answer 1

mention in comment the correct values of speed and I will solve for those values

Also, mention in comment if you have any doubt and please rate the answer if you like it
