Aboxcar of length 9.3 m and height 2.4 m is at rest on frictionless rails. inside the boxcar (whose mass when empty is 3300 kg) a tank containing 2600 kg of water is located at the left end. the tank is 1.1 m long and 2.4 m tall. at some point the walls of the tank start to leak, and the water fills the floor of the boxcar uniformly. assume that all the water stays in the boxcar. after all the water has leaked out what will be the final velocity of the boxcar? (take movement to the right as positive. assume that the mass of the boxcar is evenly distributed.)

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Aheavy piece of hanging sculpture is suspended by a90-cm-long, 5.0 g steel wire. when the wind blows hard, the wire hums at its fundamental frequency of 80hz. what is the mass of the sculpture?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
