Is it true that a pendulum clock runs faster in winter and slower in summer? Answer. It is because the time period of a pendulum clock is directly proportional to square root of the length of the pendulam so it justifies the reason as: In winter the length of the pendulum decreases and its time […]
What do plant cells have that animals cells do not?
What do plant cells have that animals cells do not? Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not. How a cell is like a […]

What affects condensation?
What affects condensation? Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation. What is the main cause of condensation? Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity […]
What three structural groups shown do all amino acids have in common?
What three structural groups shown do all amino acids have in common? All amino acids have the same backbone structure, with an amino group (the α-amino, or alpha-amino, group), a carboxyl group, an α-hydrogen, and a variety of functional groups (R) all attached to the α -carbon. What are the 4 major biological macromolecules? Types […]

Which is the best example of the law of conservation of energy quizlet?
What is the relationship between refractive index and wavelength?
What is the relationship between refractive index and wavelength? v = f. Combining the above expression for velocity with the definition of index of refraction, we find a relationship between the wavelength = v/f in a medium and the wavelength 0 = c/f in vacuum: In the above equation, the frequencies cancel because frequency does […]
