Two resistances, r1 and r2 , are connected in series across a 12 v battery. the current increases by 0.20 a when r2 is removed, leaving r1 connected across the battery. however, the current increases by just 0.10 a when r1 is removed, leaving r2 connected across the battery. find (a) r1 and (b) r2 .

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
