A 47-kg student is standing on a 28-kg cart that is free to move in any direction.
Initially, the cart is moving with a velocity of 1.5 m/s [S] relative to the floor. The student
then walks on the cart and has a net velocity of 1.0 m/s [W] relative to the floor. Use a vector scale diagram to determine the final velocity of the cart

Because they're in different places for this the temperature varies.

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 !
