Do capacitors only work in AC? It storage ability is measured in Farad “F” and “µF” or “nF” units are used for small capacitors. Keep in mind that capacitor acts as an open circuit in DC i.e. it only operable at AC voltages. Are capacitors used in AC circuits? Capacitor Charge and Discharge in an […]
Why is exercise important?
Why is exercise important? Physical activity or exercise can improve your health and reduce the risk of developing several diseases like type 2 diabetes, cancer and cardiovascular disease. Physical activity and exercise can have immediate and long-term health benefits. Most importantly, regular activity can improve your quality of life. What is the difference between physical […]
Which direction on a motion map is backwards?
Which direction on a motion map is backwards? Backwards motion is motion of the overall vehicle in the general direction opposite to the primary direction of travel during the run. If the vehicle is moving away from the start it is moving “forward” if the vehicle is moving towards the start then it is moving […]
What has the greatest capillarity?
What has the greatest capillarity? Earth Science Mid Term Review Vocabulary A B Which particle size has the greatest capillarity? silt or clay As permeability increases, what happens runoff decreases What happens to rocks that are transported by running water They become rounded and its volume will decrease What influences water flow? The volume of […]
What are the three variables in a science experiment?
What are the three variables in a science experiment? There are three main variables: independent variable, dependent variable and controlled variables. What is a controlled variable example? Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled […]
What happens to impedance when frequency increases?
What happens to impedance when frequency increases? As the frequency increase, the reactance decreases. As the frequency increases, the impedance increases. These are referred to as inductive reactance and capacitive reactance. Impedance is a crucial concept to understand as most electronic circuits utilize capacitors and inductors. What is the difference between impedance and resistance? Resistance […]
What is the relationship between living and nonliving parts of an ecosystem?
What is the relationship between living and nonliving parts of an ecosystem? You depend on each other and need the nonliving things in your home, like food, water, air, and furniture. Living things need nonliving things to survive. Without food, water, and air, living things die. Sunlight, shelter, and soil are also important for living […]
Will a high pH kill fish?
Will a high pH kill fish? Very high (greater than 9.5) or very low (less than 4.5) pH values are unsuitable for most aquatic organisms. Young fish and immature stages of aquatic insects are extremely sensitive to pH levels below 5 and may die at these low pH values. High pH levels (9-14) can harm […]
What are examples of endergonic and exergonic reactions?
What are examples of endergonic and exergonic reactions? Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release. Is Endergonic the same as endothermic? Re: Exothermic vs Exergonic […]
What do you mean by critical appreciation?
What do you mean by critical appreciation? Critical appreciation of a poem is defined as the critical reading of a poem. It does not mean criticising the poem. A critical appreciation helps in a better understanding of the verse. Meaning- Read the poem more than once to get a clear idea of what the speaker […]
