A new gel is being developed to use inside padding and helmets to cushion the body from impacts. The gel is stored in a 4.3cubic meters [m cubed ]cylindrical tank with a diameter of 2 meters [m]. The tank is pressurized to 1.4atmosphere [atm] of surface pressure to prevent evaporation. A total pressure probe located at the bottom of the tank reads 58feet of water [ft Upper H 2 Upper O].What is specific gravity of the gel contained in the tank?

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton
