The diagram below shows a circuit with a battery that provides an unknown potential difference. Work out the potential difference provided by the battery.

What is the quantity which is measured by the area occupied below the velocity- time graph?

An elevator is initially moving upward at a speed of 12.60 m/s. the elevator experiences a constant downward acceleration of magnitude 3.60 m/s2 for 2.97 s.

The steel pipe ab has a 102-mm outer diameter and a 6-mm wall thickness. knowing that arm cd is rigidly attached to the pipe, determine the principal stresses and the maximum shearing stress magnitude at point k. (round the final answers to one decimal place.) given: f = 10 kn
