The breaking force for a wire is F. what will be the breaking force for (a) Two parallel
wires of same thickness (b) a single wire of double the thickness.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

What is the speed of an object at a given moment?
