Is geothermal energy renewable and why? 2. Why is geothermal energy a renewable resource? Answer: Because its source is the almost unlimited amount of heat generated by the Earth’s core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source. How […]

Does temperature affect the flow of electricity?
Does temperature affect the flow of 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. Does electricity conduct better in […]
Is 75 beats per minute healthy?
Is 75 beats per minute healthy? Resting heart rate-the number of heart beats per minute when the body is at rest-usually changes with age, with lower rates indicative of better cardiovascular fitness and more efficient heart function. A resting heart rate of 50 to 100 beats per minute (bpm) is considered to lie within the […]
What do rows tell you on a periodic table?
What do rows tell you on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. What are the horizontal […]
Are souls dark matter?
Are souls dark matter? No. Dark matter is a not yet fully understood particle that doesn’t interact with light and that accounts for the missing mass needed to explain observed gravitational effects. There is no scientific basis for the concept of a soul; that is a religious / belief / philosophy term… Has anyone detect […]
How do we use the electromagnetic spectrum in everyday life?
How do we use the electromagnetic spectrum in everyday life? Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth. Why is the electromagnetic spectrum important? These observations […]
What are 2 everyday applications of the Doppler effect?
What are 2 everyday applications of the Doppler effect? The Doppler effect has several real-world applications. For example, besides police radar, the Doppler effect is used by meteorologists to track storms. Doctors even used the Doppler effect to diagnose heart problems. Does the Doppler effect depend on distance? Yes, the Doppler effect depends on the […]
