Off-set potential is _____________(a) difference in half-cell potentials between two electrodes(b) sum of half-cell potentials between two electrodes(c) average of half-cell potentials between two electrodes(d) complement of half-cell potentials between two electrodes |
|
Answer» The correct answer is (a) difference in half-cell potentials between two electrodes To explain: The difference in half cell potential that exists between two electrodes is called off-set potential. The differential amplifies used to measure potentials between two electrodes are generally designed to cancel the electrode offset potential so that only the signals of interest are recorded. |

Which electrodes can work even after being induced to large electric discharge such as defibrillation?(a) polarizing electrodes(b) magnetic electrodes(c) non-polarizing electrodes(d) electrolytic electrodes |
|
Answer» The correct option is (c) non-polarizing electrodes For explanation: Non-polarizing electrodes are designed to rapidly dissipate any charge imbalance induced by powerful electric discharges such as a defibrillation procedure. Rapid depolarization enables the immediate reappearance of bioelectric signals on the monitor after defibrillation. For this reason, non-polarizing electrodes have become the electrodes of choice for monitoring in the intensive care units and stress testing procedures. |

Explain the role of computer in the below mentioned hotel departments? a) Front desk b) Housekeeping c) Reservation |
|
Answer» Role of Computer Front Desk : Front desk personnel use the software to check-in and check-out of guests and to print o bills. Additionally they may check the computer to see If a room has been cleaned before checking in a guest. Finally, front desk staff enters guest names and mailing address into database to use or future reservations or to send out information. House Keeping: Housekeepers use the same software as front desk staff toverify which rooms are checking out and staying over each day.That way, they know which rooms to clean completely and which ones to simply tidy. Housekeepers use the software to communicate to the front desk, letting them know which rooms are clean, vacant and available or check-ins. Reservation: Use of computers has made the reservation or booking of rooms easy. It helps the reservation staff to rapidly check the availability of rooms when the guest calls or reserving a room. Reservation staff uses computer software programs to make reservations. Using the program, they determine which rooms and rates are available or a specific night or range of nights. |

How does the atmospheric pressure values at the sea level help us in finding the approaching storm? |
|
Answer» Standard sea level pressure is equal to 760mm of mercury. Higher air pressure gives lower sea levels an increase in air pressure of 1hpa lower and the water level by 1 cm. So high pressure over a sea area corresponds to low sea level and conversely low air pressure results in higher sea levels. |
