Which is better oxygen tank or oxygen concentrator? Oxygen concentrators are portable and easy to use and are thus better than oxygen cylinders. Although at Rs 40,000-Rs 90,000, they are more expensive than cylinders (Rs 8,000-20,000), they require very minimal maintenance. Will low oxygen make you tired? You’ll develop low blood oxygen levels, a condition […]

What are the types of radio stations? Different types of radio Conventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. Who […]

What is the efficiency ratio formula? Definition of efficiency ratio The efficiency ratio is calculated by dividing the bank’s noninterest expenses by their net income. Banks strive for lower e fficiency ratios since a lower e fficiency ratio indicates that the bank is earning more than it is spending. What is the formula for productivity? […]

Is infrared helpful or harmful? Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings. What are the advantages and disadvantages of infrared waves? 1) […]

What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]

What happens when a capacitor is short circuited? A short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. This means you can ignore the shorted capacitor — it has no […]

What type circuit connection should a light bulb be connected to maintain maximum brightness? Answer. Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go […]

What month do we get more daylight? March Why is there less sun in the winter? During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun’s […]

Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain? It is not possible for a engine to operate without rejecting any waste heat to a low temperature reservior. It violates the second law of thermodynamics, the operation of a heat engine a low temperature […]
