A battery has emf E and internal resistance r = 1.50 Ω. A 14.0 Ω resistor is connected to the battery, and the resistor consumes electrical power at a rate of 92.0 J/s. What is the emf of the battery?

A chemist must dilute 58.00ml of 13.5 aqueous silver (II) oxide solution until the concentration falls to 5.00M. He'll do this by adding distilled water to the solution until it reaches a certain final volume.

A locomotive is pulling 16 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at 0.

What is the special feature of the upper mantle?

What is the difference between weight and mass? mass and weight are both intrinsic properties of an object. if you multiply the mass of an object by the acceleration due to gravity, you will obtain the object's weight.
