A rock sits at the bottom of a fish tank and the level of the
water in the tank is noted. The rock is then put into an old
fashioned ice cube tray (made from aluminium) and is floated on the
top of the water. The level is again noted. Which of the following
is true?
a). The water level is the same before and after.
b). The water level is higher before when rock is at the bottom
of...
5. A large tank of water is full and has a depth of 10.0 m. What is the pressure at the bottom of the tank? What would the velocity of the water be if the tank was opened at the bottom?
6. A Two balloons of identical volume (radius 11.5 m) are filled with gas. The first with helium, the second with hydrogen (H2) gas. Each balloon and cage have a mass of 750 kg. What is the lift...
A tank whose bottom is a mirror is filled with water to a depth of
19.4 . A small fish floats motionless 7.10 under the surface of the
water.
part A)
What is the apparent depth of the fish when viewed at normal
incidence to the water?
Express your answer in centimeters. Use 1.33 for the index of
refraction of water.
Part B)
What is the apparent depth of the reflection of the fish in the
bottom of the tank...
A tank having vertical sides and a bottom area of 100 ft2 is used to store water. To fill the tank, water is pumped into the top at the rate given in the following table. Use Simulink to solve for and plot the water height h(t) for 0 ≤ t ≤10 min.
The small bubbles that form on the bottom of a water pot that is
being heated (before boiling) are due to dissolved air coming out
of solution.
Part A
Use Henry's law and the solubilities given below to calculate
the total volume of nitrogen and oxygen gas that should bubble out
of 1.1 L of water upon warming from 25 ?C to 50 ?C. Assume that the
water is initially saturated with nitrogen and oxygen gas at 25 ?C
and...
1)A cylindrical water-tank has a small hole 60cm above the floor
on which the tank stands. The depth of water in the tank is
1.8m.Assume the diameter of the tank to be greater than that of the
hole. 1a) Find the horizontal distance from the side of the tank to
the point on the floor where the stream of water lands. 1b) At what
other height from the base of the tank would a second hole be
drilled for water...
Water stands at a depth H in a large open tank whose side walls are vertical. A hole is made in one of the walls at a depth d below the water surface.At what distance R from the foot of the wall of the tank does the emergent stream strike the floor?How far above the bottom of the tank could the second hole be cut so that the stream emerging from it could have the same range as for the...
A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when filled. The surface area of the cylindrical part is 2πrh, and its volume is πr2h. The surface area of the hemispherical top is given by 2πr2, and its volume is given by 2πr3/3. The cost to construct the cylindrical part of the tank is $400 per square meter of surface area;...
An underground storage tank has sprung a leak, sending 184
