4. Suppose the same block is pushed at a constant velocity across a surface with friction. The applied force is again 10 N and the block is again pushed a distance of 0.35 m.

What is work done by the applied force? Is the work done positive or negative?

What is work done by the friction force? Is the work done by the friction force positive or negative?

Yes

During the 1800s. hope this !

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 !
