Electrostatic precipitator is used to control

A) Water pollution B) Noise pollution
C) Air pollution D) Solid waste
 
Answer & Explanation Answer: C) Air pollution

Explanation:

Electrostatic precipitator is used to control Air pollution. An electrostatic precipitator is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2

What does destination scan mean?

A) The shipment has arrived at a UPS facility. B) The shipment has departed a UPS facility and is on its way to the next UPS facility.
C) The shipment has arrived at the local UPS facility responsible for final delivery. D) UPS has received the shipment.
 
Answer & Explanation Answer: C) The shipment has arrived at the local UPS facility responsible for final delivery.

Explanation:

Shipment movement information is captured each time a tracking label is scanned in the UPS delivery system. There may be several days between scans if the shipment is going cross-country or moving between countries.

 

Destination Scan: The shipment has arrived at the local UPS facility responsible for final delivery.

Arrival Scan: The shipment has arrived at a UPS facility.

Departure Scan: The shipment has departed a UPS facility and is on its way to the next UPS facility.

Origin Scan: UPS has received the shipment.
