1 answer:
g100num [7]2 years ago
6 0

Explanation:

Given

mass of coolie = 40 kg

Mass of salt = 20 kg

Total mass (m) = 40 + 20 = 60 kg

Displacement (h) = 20*20 = 400 CM = 4 m

Work done (w) = ?

Power (P) = ?

We know we have the formula

work done =force × displacement

or work done = m * g * h

work done = 60×10×4

work done = 2400 joules

Similarly

power = work/time

power = MGH/time

power=60×10×4/120

power=2400/120

power= 20watt

Hope it will help you :)❤

In these areas, the surface rock is pockmarked with holes, sinkholes, and caves. The water transforms anhydrite into gypsum, one of the most common minerals on Earth.
