Determine the power of the pump. The efficiency of the pump is 65%.
If an identical spring is cut so that one part is one-fourth and the other part three-fourths of the original length, and the mass m is connected to the two parts, what would be the natural period of the system?
Evaluate the maximum height reached by the sphere, and the distance traveled by the block.
Find the velocity of the bullet and the distance it has traveled into the water after 4 seconds. Please show detailed step by step process to solution.
In order to increase production rate, a reactor setpoint was increased from 160 psig to 190 psig. The reactor pressure transmitter was recalibrated from 0- 200 psig to 0- 300 psig. What is the percent span for the old and new setpoints?
