Why is the motion of a pendulum an example of simple harmonic motion? because even at large amplitudes there is restoring force pulling the pendulum toward mean position and its acceleration is directly proportional to the displacement. … Why does SHM occur? Simple Harmonic Motion (SHM) is defined as an oscillation whose restoring force is […]
What stays green all year round?
What stays green all year round? Evergreen plants and trees stay green all year long — hundreds of species thrive in climates around the world, including U. S. Department of Agriculture plant hardiness zones 8 through 10. Flowering evergreen plants, trees, shrubs, ground covers and vines bring color to gardens and landscapes. What is the […]
How do you reduce standing waves?
How do you reduce standing waves? Low end sounds create standing waves when the reflected sound between walls is directly opposite in phase. By cutting the frequency, you can eliminate the problem. What are the effects of harmonics? Effects of harmonics in the power system Increase in installation and utility costs. Downtime and loss of […]
Why are bones spongy?
Why are bones spongy? Spongy bone reduces the density of bone and allows the ends of long bones to compress as the result of stresses applied to the bone. Spongy bone is prominent in areas of bones that are not heavily stressed or where stresses arrive from many directions. Is spongy bone soft? Though spongy […]
Why is SI easier than the English system?
Why is SI easier than the English system? There are several reasons why SI is preferred to the old English system of measurement: SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units. The prefixes used in SI are from Latin and Greek, and […]
What is the role of parent material in soil formation?
What is the role of parent material in soil formation? The parent material of a soil determines the original supply of those nutrient elements that are released by weathering and influences the balance between nutrient loss and retention. Organic acids and exudates produced by microorganisms and plants enhance the weathering of minerals and the release […]
What does the radial velocity method measure?
What does the radial velocity method measure? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This allows astronomers to determine the inclination of the planet’s orbit, which enables the measurement of the planet’s actual mass. Why is the radial velocity method biased towards high mass […]
What is killing the coral reefs?
What is killing the coral reefs? Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. Genetics is also becoming a larger area of coral research, giving scientists hope they might one day restore reefs with more heat tolerant coral. How are humans killing coral reefs? […]
Can I check my iron levels at home?
Can I check my iron levels at home? The BIOSAFEAnemia Meter is the first FDA-approved, hand-held device that can be conveniently used at home to test hemoglobin levels (Figure 1). Low levels of hemoglobin may indicate anemia. Thus, the Anemia Meter may be used as an additional screening method. It is not recommended for use […]
What are the classes of dangerous goods?
What are the classes of dangerous goods? What are dangerous goods? Class 1: Explosives. Class 2: Gases. Class 3: Flammable liquids. Class 4: Flammable solids; substances liable to spontaneous combustion; substances which, on contact with water, emit flammable gases. Class 5: Oxidizing substances and organic peroxides. Class 6: Toxic and infectious substances. Class 7: Radioactive […]
