Avery long, rectangular loop of wire can slide without friction on a horizontal surface. initially the loop has part of its area in a region of uniform magnetic field that has magnitude b = 2.9 t and is perpendicular to the plane of the loop. the loop has dimension 4.0 cm by 60 cm, mass 24 g, and resistance r = 5.0 × 10^−3 ω. the loop is initially at rest; then a constance force fext = 0.18 n is apllied to the loop to pull it out of the field. (a) what is the acceleration of the loop when v = 3.00 cm/s? (b) what is the loop’s terminal speed when the acceleration becomes zero?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
