The external and internal radii of a glass tube of length 0.289 m are 0.0086 m & 0.0063 m respectively. It is surrounded by a steam jacket and water is passed through the tube. If water is supplied at 15.3 degree C and water at a temperature 20.2 degree C emerges at the outlet and if the conductivity of the glass is 0.63 SI unit, find the rate of flow of water.

How correct is the measurement of the mass of planets and stars? There is no way we can know correctly how heavy are stars or even galaxies . Even the formula won't work cause we don't know the mass of moon to find the mass of earth . How can we prove how heavy is a mountain without knowing 100% the material and actual volume , measuring gigantic objects is impossible with our technology

A small hole of radius 0.1 mm is present at the bottom of a tumbler. Up to what maximum height may water be stored inside the tumbler so that no water leaks out through the whole? [ given that the surface tension of water is 7.1 x 10^(-2) N/m ]

If a 1.1x1011 N force is applied on each 100.0 m cylinder of aluminum, brass and steel with a radius of 10.0 m
(figure 8 ). Find the final length of each cylinder. Create a 1000.0 kg, cylindrical boat made of steel such that it is
able to hold a 1500.0 kg, 1.5 m3
container. Of this same boat, what is the pressure that the bottom of the boat
exerts on the water (3 Extra Credit points: What are the three principle components of steel?)

Calculate the moment of inertia for the following examples in figure 5 given r = 0.5 m and m = 500.0 kg. How
much rotational energy does each example have if ω = 120.0 rad/sec. If each example had translational motion
through space of 100.0 m/s, what would be the total kinetic energy of each example (NOTE: For 5f, R1 = 0.25 m
and R2 = 0.5 m)?

Each object, starting from left to right, has a mass of 20.0 kg, 25.0 kg and 5.0 kg respectively. They are attached
by rope and pulled by an individual (see figure 4). Their unified acceleration is 5.5 m/s2
in the x direction. What is
the horizontal force applied on the block system? What type of horizontal force is applied on all three blocks (e.g.
tensional, compressional, etc)? What is the horizontal force applied on m3? What is the work done by all the
blocks if they all start from rest, and are accelerated with the force you calculated for 10.0 seconds? If there is a
220.0 N frictional force is applied to the system, will the system continue to accelerate? If so, by how much?
Explain your reasoning

A brick is on 45° incline (fig 3a). Draw the Free Body Diagram. What is the net force on the brick if it is
stationary? What must the coefficient of static friction (µs) be to have zero net work done on the block? If the
block is 125 kg, what is the work done by gravity, by friction and the net work on the block if it slides down for 5.0
seconds and assuming µk to be 1/8 that of µs? Starting at rest on a flat, frictionless surface, calculate the
acceleration needed to attain the same amount of work as the system above over a 10.5 second period.
