Answer:
W = 7056 J
Explanation:
Given that,
Mass of a load, m = 60 kg
Distance moved, d = 12 m
We need to find the amount of work. The work done by an object is given by :
W = Fd
So,
W = mg×d
W = 60 kg × 9.8 m/s²×12 m
W = 7056 J
So, the amount of work done is 7056 J.
Chemical change, we can't change the bread back the way it was before
Hope this helps!

Answer:
35.489km
Explanation:
a diagram illustrating the question is attached
now, applying cosine rule to find the displacement c
cosine rule;
c²=a²+b²-2abCos ∅
c²=50²+80²-2(50)(80)Cos 38°
c²=2500 + 6400 - (8000×0.9951)
c²=8900-7640.589
c²=1259.411
c=
c=35.49km
