An iron rod is :
a: a good conductor of heat and electricity, but not magnetic
b: magnetic and a good conductor of heat, but is an insulator of electricity
c: magnetic and a good conductor of heat and electricity
d: not magnetic and an insulator of heat and electricity
a and d are out

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
