Consider two cylindrical conductors made of the same ohmic material. v1 ~e1 i1 ℓ1 r1 b v2 ~e2 i2 ℓ2 r2 b if rho2 = rho1 , r2 = 2 r1 , ℓ2 = 2 ℓ1 , and v2 = v1 , find the ratio r2 r1 of the resistances

Apassenger walks toward the rear of a moving train. describe her motion as seen from a reference point on the train. then describe it from a reference point on the ground

Describe the function of the endomembrane system? what organelles are involved?

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
