Answer:
W=0.94J
Explanation:
Electrostatic potential energy is the energy that results from the position of a charge in an electric field. Therefore, the work done to move a charge from point 1 to point 2 will be the change in electrostatic potential energy between point 1 and point 2.
This energy is given by:
So, the work done to move the chargue is:
The work is positive since the potential energy in 1 is greater than 2.
Answer:
the correct one is C
Explanation:
For this exercise we must use the work definition
W = F. s
Where the bold characters indicate vectors and the point is the scalar producer
W = F s cos θ
Where θ is the angles between force and displacement.
Let us support this in our case. The cable creates an upward tension and with the elevator going down the angle between them is 180º so the work of the cable on the elevator is negative.
The evade has a downward force, its weight so the force goes down and the displacement goes down, as both are in the same direction the work is positive
When examining the statements the correct one is C
C a sliding Door ig idk tell me the right answer
A. Through the direct contact of particles
Answer: the number of electrons on the shell, the number of protons and neutrons inside the nucleus. Also their charges differ ie electrons have negative charges, protons have positive charges while the neurons have no charge.
