What are the three types of seismographs? To overcome this problem, modern seismograph stations have three separate instruments to record horizontal waves – (1) one to record the north-south waves, (2) another to record east-west waves, and (3) a vertical one in which a weight resting on a spring tends to stand still and record […]
What color has the greatest amplitude?
What color has the greatest amplitude? red light waves What happens when you increase the frequency? When you increase the frequency of a sound wave, the sound waves get compressed and we hear the sound at a faster rate. The pitch of the sound increases. What happens to the waves as you increase the amplitude? […]

Why do covalent compounds have low melting and boiling point?
Why do covalent compounds have low melting and boiling point? Covalent bonds are very stable and the interatomic forces are quite strong. But, the intermolecular forces between covalent compounds are weak. Since lower heat (energy) is capable of breaking these weak intermolecular forces, therefore the melting and boiling points of covalent compounds is low. Why […]
What was the main goal of the Human Genome Project?
What was the main goal of the Human Genome Project? One goal of the project was to accurately sequence the 3 billion nucleotide base pairs in the human genome. A second goal was to map and identify all of the human genes present in the DNA sequence. (The number of genes is currently estimated to […]
What are the patterns of population growth?
What are the patterns of population growth? Two types of population growth patterns may occur depending on specific environmental conditions: An exponential growth pattern (J curve) occurs in an ideal, unlimited environment. A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth. What are the two factors that affect the […]
