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. […]

Can K-type stars support life? K stars can live for 17 to 70 billion years, much longer than sunlike stars, which shine on the main sequence for only about 10 billion years. The longer lifespan of a K star would give life on an orbiting planet more time to evolve, if it ever got started. […]

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 we sit on a cloud? Although we can’t really touch clouds you could walk through one. In fact that’s what fog is: a cloud that’s formed close to the ground instead of high in the sky. We can’t touch fog but we can move through it. Although it’s fun to imagine sitting on a […]
