<span>Engineers place tolerance on dimensions since
the when engineers use tolerance, buildings and constructions projects like
tall towers, roads, and bridges become more reliable, strong and stable. In
harnessing tolerance, the end product that is made by the engineers,
specifically buildings like schools, hospitals, malls and skyways are sturdy
and dependable.</span>
Answer:
The answer is C. 120,000 J.
Explanation:
The work done in lifting an object to a height of 2 m is equal to two times the weight of the object. W = 2×mg
<h3>
Explanation:</h3>
Consider the mass of object to be m kg. The amount of work done to lift an object depends on the force required and the distance to which force is applied. To lift the object to a height of 2 m; Let F be the amount of force applied.
..................(1)
Where,
W=Work done
F= Amount of applied force
h=Height to which object is to be lifted
Applied force is equal to the weight of the object. Therefore,
..............(2)
Where,
m=Mass of the object
g=gravitational acceleration
Substituting (2) in (1), we get
For height = 2 m,
The work done in lifting an object to a height of 2 m is equal to twice the weight of the object.
Most of the oceans salts come from the gradual processes of weathering, erosion, and deposition
