Water flows steadily along uniform Flow tube of Cross section area 20cm^2. The total pressure is 3×104pa and static pressure is 2.5×10^4pa. calculate the velocity of the fluid?
help me please

Oxygen and nutrients are moved through the body by the: a. circulatory system c. lymphatic system b. digestive system d. reproductive system

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
