Explanation:
In the picture, i hope that it's a clear.
The strength of the fireman in vertical direction will be given by F = m * g. Then, the work done will be given by definition by W = F * d. Substituting the expression of the Force in that of the work, we have that the work will be W = m * g * d. Substituting the given values and assuming that g = 10m / s ^ 2, we have a total work of W = (73) * (10) * (9) = 6570 J
The water has reached boiling and is beginning to evaporate. Plz give most brainly!
Answer:
A 1 kg block sliding to the right on a level, frictionless surface with a speed
