A force = (3x i + 3yj ) N acts on an object as it moves in the x direction from the origin to x = 4.92 m. Find the work W = ·ddone on the object by the force.
How do I make a circuit that can find the resistance of different electrical conductors (Copper, Steel, Iron and Aluminium) - what sort of experiment would i have to conduct and how?
you are able to swim at 1.4 m/s. one day you swim directly across a river that has a uniform water flow of 6.1 m/s. what is your resultant swimming velocity - both magnitude and direction (given as an angle with respect to the shore)?
