Answer:
A 35 m/s
Explanation:
Speed of any object is scalar quantity while velocity is a vector. The scalar quantity is represented only by magnitude it doesn't need direction.
Hence, option A is correct as all other options have direction as well.

Calories, however you might want to back up my answer. I havent studied this topic in a while.
<span>The importance of discovering gravitational
waves are; one, we can measure the activity between two bodies in orbit in the
universe, two, scientist can estimate the merging of two bodies in the universe
every 15 minutes by using LIGO and three, we can know the behavior of other
bodies that we did not know exist.</span>
Answer:
A scientific law is a statement that summarizes a pattern found in nature.
Explanation:
The distance covered as the crane does work is 76 m.
Recall that the work done in lifting the crane is the product of force and distance covered. In this case, we are talking about the distance through which the crane is raised. Therefore;
Work done = Fs
F = Force applied
s = Distance covered
Substituting values;
Work done/Force applied = Distance covered
Distance covered = 9,500 J/125 N
Distance covered = 76 m
