4. going back to the situation in question 1 (pipe narrows from an area of 2.0 cm2 to an area of 1.0 cm2 ; the speed of the water in the larger part of the pipe is 2.0 m/s. you already calculated the speed in the narrow part in question 1). the pipe is horizontal so the height of the water doesn’t change. suppose you measure the pressure in the larger part of the pipe to be 8,000 pa. what is the pressure in the narrow part

Explanation:

we know from continuity equation

A1 V1 = A2 V2

V2 = 4 m/s

we know, so we have

after solving we get

be subject to a force andchange its motion

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
