Which statement describes the relationship of resistance and current? 1.resistance is directly proportional to current because r = . 2.resistance is inversely proportional to current because r = . 3.resistance is directly proportional to current because r = vi. 4.resistance is inversely proportional to current because r = vi.

Use the table to answer question 22 23 and 24.

Which situation will produce the greatest change of momentum

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
