Starting from rest, a 4.70-kg block slides 2.10 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is ?k = 0.436.
(a) Determine the work done by the force of gravity.(b) Determine the work done by the friction force between block and incline.(c) Determine the work done by the normal force.(d) Qualitatively, how would the answers change if a shorter ramp at a steeper angle were used to span the same vertical height?
Finding appropriate source for the electrical load, Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blo..
A 100-watt motor (60% efficient) is used to raise a 100-kilogram load 5 meters into the air. If the task takes 65 seconds to complete, how heavy was the load in units of kilograms
A simple voltmeter with a full-scale reading of 50(V) is required. Use a d'Arsonval movement with a rating of 20(mV) at 1 (mA). Calculate the value of the voltmeter resistor, Rv, required to achieve these design specifications.
