This would be the definition of a resistor. These components inhibit or “resist” the flow of a current.
Hope this helps!
Answer:
<h2>1)Straw : When a man sucks up the fluid from straw the pressure inside is moderately low and accordingly atmospheric pressure outside powers up the fluid into straw. 2)Vacuum cleaner : When a vacuum cleaner is exchanged on, the pressure inside tumble off because of air inside.</h2>
Answer : 
Explanation :
Given that,
Charge of particle 1 = 
Distance x = 6 cm
Charge of particle 2 = 
Distance x = 27 cm
Total distance = 

Particle 1 is at (6,0) and particle 2 is at (27,0) .
Therefore, midway (16.5, 0)
Now, 
Formula of electric field

Now, the the electric field due to particle 1



Similarly, the electric field due to particle 2

Resultant Electric field


Hence, this is the required answer.
