Does heat affect electricity? Temperature affects how electricity flows through an electrical circuit by changing the speed at which the electrons travel. This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures. How can you heat your home without electricity? […]
What are the two main types of eclipses?
Is a pure compound?
Is a pure compound? *Note: pure oxygen gas consists of molecules but it is still considered an element, rather than a compound, as the molecules are made up of a single type of element. Compounds are made up of one or more element….Pure Substances. Pure Substance Element or Compound? Consists of: Ammonia (NH3) compound ammonia […]
What happens when a capacitor is short circuited?
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 […]
Is infrared helpful or harmful?
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) […]
How does technology help the economy?
How does technology help the economy? In economics, it is widely accepted that technology is the key driver of economic growth of countries, regions and cities. Technological progress allows for the more efficient production of more and better goods and services, which is what prosperity depends on. How can technology protect us? Advancements of modern […]
What is the efficiency ratio formula?
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? […]
When the pH of an aqueous solution is changed from 1 to 2?
What happens to the stopping distance if velocity of a car is doubled?
What happens to the stopping distance if velocity of a car is doubled? When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four. This piece of information will be important for determining your total stopping distance. What […]
What type circuit connection should a light bulb be connected to maintain maximum brightness?
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 […]
