Answer:
Explanation:
<em>Work </em>is the change in kinetic energy and may be calculated as the product of the force in the direction of the displacement times the displacement.
For a differential displacement, Δx, and a variable force, f(x), the differential work done is:
And the total work done from a point xi to xf is:
Thus, for this problem we have:
- f(x) =
The symbol is just indicating that the direction of the force is in the same direction of the displacement.
Integrating you get:
And that is 54.8697 joules (since the units for x are meter and the units for f(x) are newtons).
Rounded to two significant digits: 55 joules.
Answer:
tensional force
Explanation:
It usually exist in fluid or any liquid substance where by an object is put before it
e.g An ant can walk on water without submersed in it.
Answer:through a small space through atoms

Answer:
P = 86956.52 Pa
Explanation:
Data:
- F = 800 N
- A = 0.0092 m²
- P = ?
Use the formula:
Replace and solve:
The pressure it exerts on the ground is <u>86956.52 Pascal.</u>
