Why are the intestines shorter in a living person than in a dead person? The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone). Which is the largest part […]
Can you differentiate tangential velocity and tangential acceleration?
Can you differentiate tangential velocity and tangential acceleration? If the tangential velocity is not changing directions, then the object is not moving in a circle. Tangential acceleration results from the change in magnitude of the tangential velocity of an object. An object can move in a circle and not have any tangential acceleration. How do […]
Is damped oscillation?
Is damped oscillation? An oscillator is anything that has a rhythmic periodic response. A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. What causes damped oscillation? a decrease in intensity of oscillations with […]
Does photoelectric current depend on frequency?
Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
What is rapid combustion give an example?
What is rapid combustion give an example? Burning of LPG is an example of rapid combustion. In this combustion, the combustion of combustible material is complete. LPG burns rapidly and produces heat and light. What is meant by spontaneous combustion? Spontaneous combustion, the outbreak of fire without application of heat from an external source. Spontaneous […]
What is meant by the color of law?
How do you wind a 3 phase motor?
How do you wind a 3 phase motor? The three-phase motor stator is wound by winding a first coil clockwise, and then relatively indexing the winding head and the stator by 180 electrical degrees before winding the second coil counterclockwise. Can a Tesla do a burnout? Who knew the Model 3 could do burnouts like […]
Does it matter where you put the dots on a Lewis structure?
Does it matter where you put the dots on a Lewis structure? In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. Again, it does not matter on which sides […]
Where do most humans live?
Where do most humans live? The world’s two most populated countries, China and India, together constitute about 36% of the world’s population. Africa is the second most populated continent, with around 1.34 billion people, or 17% of the world’s population. How many years do human live? 79 years What country has the least population? Vatican City […]
