Question

(1)A river 3m deep and 40m wide is into the sea at the rate of 2km/h . how much water will fall into the sea in a minute
(2) water flows in a tank 60m×40m at the base through the pipe whose cross section is 2dm×1.5dm at the speed of 8km/h . In what time the water will be 5m deep ​

Answer 1

Answer:

as u have asked here is Ur answer

Difference between xylem and phloem is an important aspect of Biology. Furthermore, these two are types of vascular tissues that exist in plants and they transport the essential materials among the various parts of the plants. Moreover, xylem and phloem constitute vascular bundles when they are together.

hope it is helpful to you

and I have also sent u 1) answer so pls see to it

Answer 2

Answer:

Given, a river 3m deep and 40m wide is flowing at the rate of 2km per hour.

Area of cross section of the river = 3 * 40 = 120 m2

Now, volume of water flowing through this cross section in every minute = Area * rate

                                                                                                 = 120 * 2 km/hr

                                                                                                 = 120 * (2000/60) m/min

                                                                                                 = 2 * 2000

                                                                                                 = 4000 m3

Since 1 m3 = 1000 litres

So, 4000 m3 = 4000 * 1000 litres = 4000000 litres
