Answer 1

You know, when you log on here you see all these posts with subjects like math, science, psychology, English, etc. Why do you think that Cowdray Park will be interpreted as a school subject?

work = force * distance

So, just plug in your numbers.

Answer 2

Formula is
Work done= force(N) × distance moved (m)
In question distance value is in km so first we have to change it to m.
Sol:
Making value of distance right
1×100=100m.
Now apply formula
Work= 1500(N) × 100(m)
Work Done= 150,000.
