Please help Fast I do not know

So the answer to this question would be C. 400 J

Explanation:

Now for this problem, what is given is a 40 Newtons which would represent the force to be applied to the object, and a distance of 10 meters after the application of the said force. When these two combine, work is done. The unit for work is Joules and this is what we are looking for. The formula to get Joules or for work would be the force applied to the object multiplied by the distance that it travelled after the application of the force. It looks like this

work = force x distance

Joules = Newtons x meter

so let us substitute the variables to their corresponding places

Joules = 40 N x 10 m

Joules = 400 J

IF THIS HELPED YOU PLEASE MARK ME BRAINLIEST! THANKS! :

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
