(10 points) a leaky bucket was pulled from the ground up to 8 meters above the ground at a constant rate of 0.5 meters per second. initially, the bucket contained 25 liters of water. the water was leaking out of the bucket at a constant rate of 0.3 liters per second. assume that both the bucket and the rope have neglible weight. the acceleration due to gravity is 9.8 m/s2 . the density of water is 1 kilogram per liter. find the total amount of work done (in joules) when the bucket of water was moved from the ground to 8 meters above the ground.

bc its just b

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
