An arrow pointing from the bottom of the ramp to the top, I assume it would be friction.
here three vectors are given as
now we will find the sum of all three
so its magnitude will be
So here this resultant will be same in all three cases as it will have same figure in all cases
Answer:
Pascal's law (also Pascal's principle[1][2][3] or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.[4] The law was established by French mathematician Blaise Pascal in 1653 and published in 1663.[5][6]
Electric current is the movement of electrons through a wire. Electric current is measured in amperes (amps) and refers to the number of charges that move through the wire per second.
