Two boys are sitting face to face on a frictionless surface of ice. Bob has a mass of 20kg and Frank has a mass of 40kg. The two boys push off one another with a force lasting 0.25 seconds. Frank begins sliding to the right at a speed of 3.14 m/s Calculate speed and direction of Bob after the push.

Calculate the magnitude of the force between them during the push off.

The anwser is: wave a has a greater pitch and frequency.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
