Answer:
W = 0 :The work done on the wall is zero,because the wall is not moving
Explanation:
Work theory
Work is the product of a force applied to a body and the displacement of the body in the direction of this force.
W= F*d Formula (1)
W: Work (Joules) (J)
F: force applied (N)
d=displacement of the body (m)
The work is positive (W+) if the force goes in the same direction of movement.
The work is negative (W-)if the force goes in the opposite direction to the movement
Data
F= 400-N
d= 0
Problem development
We apply formula (1) to calculate the work done on the wall:
W= 400*0
W=0
Answer: hello options related to your question is missing attached below is the missing part of your question
answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )
Explanation:
When the Charge is first, Furthest away and second and closest to the source charge. <em>The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source </em><em>when Furthest away the bond with charge will be less effective </em>
The acceleration of an object is equal to the net force acting on the object divided by the object's mass.
Answer:
Local atmospheric pressure in kPa = 97.932 kPa
Local atmospheric pressure in mm Hg = 734.78 mm Hg
Explanation:
Given:
- = absolute pressure = 46 kPa = 46000 kPa
- = density of air =
- = density of mercury =
- = altitude of the plane = 6400 m
Assume:
- = pressure decrease due to air at height h
- = local atmospheric pressure
As we go up the altitude, the pressure decreases. So, the reading of the pressure will be equal to the decrease in pressure due to height subtracted from the local atmospheric pressure.
Now, conversion of the local atmospheric pressure is quite simple. let us assume that height of H mm of Hg is required to exert a pressure equivalent to the local atmospheric pressure.
Hence, 734.78 mm Hg is the local atmospheric pressure in mm Hg.
The producers, produce what ever they are producing for the consumers to obtain. The decomposers, decompose the things when the producers and consumers are done with them. Therefore, it is a cycle!
