True or false explain y....the faster a fluid moves ,the higher pressure that fluid exerts?

False. Bernoulli's principle states that an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's gravitational potential energy. The faster the fluid moves the less pressure it exerts. Think of it this way water through a hose. If you squeeze the hose the water comes out faster but the pressure that the water is exerting on the insides of the hose decreases.
