21. First part - We say work is done when a force is applied on an object and that force is making that object move. SI unit of work is joule.
Second part - work = f × s = 250 × 50 = 12500 joule.
This is frictional force
23. Use manure instead of fertilizers. And use Eco-friendly things in agriculture
