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

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Who was the first scientist to measure speed as distance over time?
