Answer:
The distance he moved the soil is 32.97 m.
Explanation:
Given;
force exerted on the wheelbarrow, F = 185 N
work done in moving the soil, w = 6.1 kJ = 6100
The work done in moving the soil is given as;
Work done = force x distance he moved the soil
W = F x d
d = W / F
d = (6100) / (185)
d = 32.97 m
Therefore, the distance he moved the soil is 32.97 m.
Answer:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
Friction, engine thrust, normal reaction and weight, these are the forces acting on motor when it moves in a straight line
