What can I use for main water line?
What can I use for main water line? PVC is an acronym that stands for polyvinyl chloride. Of the different types of plastic pipe used for water supply, PVC has a wide variety of plumbing uses, from drainage pipe to water mains. It is most commonly used for irrigation piping, home, and building supply piping. […]
What are the types of systematic errors?
What are the types of systematic errors? Systematic errors may be of four kinds: Instrumental. For example, a poorly calibrated instrument such as a thermometer that reads 102 oC when immersed in boiling water and 2 oC when immersed in ice water at atmospheric pressure. Observational. For example, parallax in reading a meter scale. Environmental. […]
Is there a black star?
Is there a black star? A black star is a gravitational object composed of matter. It is a theoretical alternative to the black hole concept from general relativity. The theoretical construct was created through the use of semiclassical gravity theory. It will appear almost exactly like a black hole. What does a black star stand […]
At what pH enzymes are highly efficient?
At what pH enzymes are highly efficient? The enzyme activity is maximum at optimum pH which is between 5-7. Why do enzymes denature at high and low pH? Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of […]
Can K-type stars support life?
What is the relationship between mass and weight of an object?
What happens to wavelength of energy increases?
What happens to wavelength of energy increases? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
What are the negative effects of technology in the workplace?
What are the negative effects of technology in the workplace? Distraction is one of the most harmful impacts of technology at the workplace. The result? Cognitive scientist Gloria Mark says, is, people compensating for interruptions by working faster, leading to stress, frustration and pressure. All of this leads to poor productivity. Why the technology is […]
Is it safe to heat magnets?
Is it safe to heat magnets? When heated above 176° Fahrenheit (80° Celsius), magnets will quickly lose their magnetic properties. The magnet will become permanently demagnetized if exposed to these temperatures for a certain length of time or heated at a significantly higher temperature (Curie temperature). Why Does heat destroy magnets? Excessive heat causes atoms […]
