Answer:
Its duration is 1.85*10⁻³ s or 1.85 ms
Explanation:
The intensity of electric current I is defined as the amount of electric charge Q (measured in Coulombs) that passes through a section of a conductor in each unit of time. The letter I is used to name the Intensity and its unit is the Ampere (A).
The intensity of electric current is expressed as:
where:
I: Intensity expressed in Amps (A)
Q: Electric charge expressed in Coulombs (C)
t: Time expressed in seconds (s)
Being:
Replacing:
Solving:
19500 A*t= 36 C
t= 1.85*10⁻³ s= 1.85 ms (being 1 s= 1,000 ms)
<u><em>Its duration is 1.85*10⁻³ s or 1.85 ms</em></u>
Because their is nothing at the geographical poles that attracts the magnet
Answer:
the ans i 1 ohm
Explanation:
if i cut a resistor of 9 ohm into 3 equal parts then each resistor will have a resistance of 3 ohm and if they are in parallel combination the net resistance will be R
so 1/R=1/R1+1/R2+1/R3
1/R=1/3+1/3+1/3
R=1
If we define each of the systems that are given in the options we will have to:
Air conditioning is the air treatment that modifies its conditions to suit certain needs, i.e., the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioners are also responsible for controlling humidity in closed rooms.
Positive Pressurization is a pressure within a system that is greater than the surrounding environment. Consequently, if there is any leakage of the system with positive pressure, it will leave the surrounding environment. There is no temperature or humidity control here
Ventilation is done by artificially creating depressions or overpressures in air distribution ducts or building areas. The fans are mechanically responsible for increasing the volume flow of air in a system. Moisture is not controlled directly.
Therefore the correct answer is A.
