A large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point18.9 m below the water level. The rate of flow from the leak is 3.00 multiply.gif 10-3 m3/min.
(a) Determine the speed at which the water leaves the hole.
m/s
(b) Determine the diameter of the hole.
mm

Two charged dust particles exert a force of 4.30×10-2 N on each other. What would be the force if they are moved so they are only one-sixth as far apart.
light of wavelength 550 nm of air is found to travel at 1.96 x 10^8 m/s in a certain liquid. what is the frequency of the light in air
An 825-N sled is pulled a distance of 161 m. The task requires 1.50 ^ 10^4 J of work and is done by pulling on a rope with a force of 137 N. At what angle is the rope held.
in a typical Van de Graaff linear accelerator, protons are accelerated through a potential difference of 20 MV. What is their kinetic energy if they started from rest
An initially motionless test car is accelerated uniformly to 145km/h in 8.28s before striking a simulated deer. The car is in contact with the faux fawn for .815s, after which the car is measured to be traveling at 82.0km/h. What is the magnitude ..
In a nuclear experiment a proton with kinetic energy 1.5 MeV moves in a circular path in a uniform magnetic field. What energy (in MeV) must (a) an alpha particle (q = +2e, m = 4.0 u) and (b) a deuteron (q = +e, m = 2.0 u) have if they are to circ..
