C) A battery of emf, E drives a current of 0.25A when connected to a 5.5ohms resistor. When the 5.5ohms resistor is replaced with a 2.5ohms resistor, the current flowing becomes 0.5A.
Using E=V+Ir, Find the emf, E of the battery.

i'm hoping this is like a multiple answer question. if it is then it would be, the location of the plants and also the height of the plants since one she wants to know where in her garden the chamomile grows best. but also to see which plants grew better in the location she also has to measure the plant itself. (if you can only choose one answer than it would be c).

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
