Answer:
W = 0.562 J
Explanation:
Initial potential energy of two point charges is given as
here we have
now we have
now at final position the distance between two charges is given as
Now final energy is given as
Now the work done to change the position of charge is given as
A food handler cannot identify if food has been contaminated with pathogens by its smell, look and taste. The best way to ensure food is pathogen-free is to follow safe food handler’s practices.
AC motors work a slightly different way: they pass alternating current through opposing pairs of magnets to create a rotating magnetic field, which "induces" (creates) a magnetic field in the motor's rotor, causing it to spin around. You can read more about this in our article on AC induction motors.
If that statement were true, then you would never have any reason to eat.
It might taste good for a while, but it would never help you stand up and
move around.
Where WOULD you get the energy to stand up and walk, if it didn't
come from food ? ?
The whole idea is pretty absurd. I guess the statement is not true.
Answer:
Technician A only
Explanation:
Both high-side pressures and low-side pressures are low with the engine running and the selector set to the air-conditioning position. Technician A says that the system is undercharged. Technician B says the cooling fan could be inoperative. Which technician is correct?
usually . An overcharged system will result in lower than normal low side pressures
An undercharged system will not enable the compressor to create pressure. As a result of the low amount of refrigerant, the cooling ability is reduced. When we say undercharged, we mean the refrigerant in the system is low, so the both the high side pressures and low side pressures will be low.
