Atank container has the dimensions listed below. the air pressure inside the top of the tank is 52kpa (gage). calculate the force (differential force) on the bottom of the container (answer in kn). note the tank top is sealed, not open to atmosphere, it is pressurized to 52kpa. the specific weight of water on earth at 5°c is 62.43 lbf/ft3 or 9.807 kn/m3

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
