Do electrons physically move?
Do electrons physically move? Electrons do physically move when a voltage is applied – extremely slowly. This works out to 8.4 cm/hour. Can an electron move? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move […]

Which information did the Glomar Challenger study in 1968? ANSWER: Glomar Challenger studies about the “age of rocks in various places in the ocean” […]
How do you tell if you have had a seizure?
How do you tell if you have had a seizure? General symptoms or warning signs of a seizure can include: Staring. Jerking movements of the arms and legs. Stiffening of the body. Loss of consciousness. Breathing problems or stopping breathing. Loss of bowel or bladder control. Falling suddenly for no apparent reason, especially when associated […]
What is considered an observation in a data set?
What is considered an observation in a data set? An observation in statistics is a value of something of interest you’re measuring or counting during a study or experiment: a person’s height, a bank account value at a certain point in time, or number of animals. “Observation unit” means the same thing in this context. […]
How can we reduce harmonics in power system?
How can we reduce harmonics in power system? To attentuate harmonics, users can use passive filters, inductive reactors, phase-shifting transformers, active filters, or multi-pulse converter sections. Passive filters apply tuned series L-C circuits (circuits with inductance and capacitance) that attentuate specific harmonic frequencies. How much current total harmonic distortion is acceptable? increased temperatures and interference […]
Can two waves with different frequencies interfere?
Can two waves with different frequencies interfere? 2 Answers. No; wave interference takes place whenever two waves of any frequency, same, nearly the same or widely different interact. An air molecule next to your ear, for example, can only respond to the sum of all the different sound waves reaching it at any moment. What […]

Male gender. Heredity (including race) Tobacco smoke. High blood cholesterol. High blood pressure. Physical inactivity. Obesity and being overweight. What […]
What allows to float?
What allows to float? Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. When an object floats, it pushes water out of the […]
Is sound a standing wave?
Is sound a standing wave? Standing sound waves open and closed tubes. Sound waves are longitudinal waves in a medium such as air. The loudness or volume of the sound also increases with wave amplitude. In open and closed tubes, sounds waves can exist as standing waves as long as there is at least one […]
