Answer: A Net Force is where two forces that are acting on an object are equal, but in opposite directions.
Answer:
A

Answer:
Only if that object is being moved while carried
Explanation:
Work = Force • distance travelled
While holding an object would need force equal to that objects mass multiplied by 9.8, if it hasn't moved, then no work is done.
if you were to carry the object and have it travel some distance, then work would be done on that object.

:) just sayin
Answer:
65 N
Explanation:
ΣForces = (mass)(acceleration) = all other forces being enacted
The force that the rope exerts is just the tension in the rope caused by the bucket being lifted. I'll take up to be positive and down to be negative, so the tension is an upward force vector and the bucket weight is a downward force vector. By taking into account all the forces involved here, we get the formula:
ΣForces=ma=Tension-mg
- m is the bucket mass
- g is gravity pulling down on the bucket, I'm also taking gravity as 10m/s²
- a is the upward acceleration of the bucket
By isolating Tension we get Tension=ma+mg
Tension = m(a+g)
Tension = 5kg(3+10)m/s²
Tension = (5)(13)N
Tension = 65N
