How can standing waves be prevented? The solution to stopping a standing wave is cutting the offending frequency of the related instrument….Standing waves can be caused when waves bounce between; Opposite walls. Four sides of the room. All six sides of the room (given most rooms have four walls, a floor, and a ceiling!) Why […]
What is the partial pressure of oxygen at sea level?
What is the partial pressure of oxygen at sea level? 160 mm Hg How do you find the partial pressure of CO2? Calculate the partial pressures for each gas. For the partial pressure of carbon dioxide, we multiply 0.2 mol by our constant of 0.0821 and our temperature of 310 degrees K, then divide by […]
Why are telescopes limited?
Why are telescopes limited? The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. Is the human eye diffraction limited? The human eye is close to being fully diffraction-limited, at least for photopic (cone-based) vision at the center […]
How can detergents cause pollution?
How can detergents cause pollution? Phosphates in detergents can lead to freshwater algal blooms that releases toxins and deplete oxygen in waterways. When the algae decompose, they use up the oxygen available for aquatic life. Does Soap pollute rivers? All soaps, unfortunately even biodegradable ones, can contaminate fresh water sources. Materials are usually deemed biodegradable […]
Is it OK to put dry ice in the freezer?
Did cannonballs have explosives in them?
What instrument can make any sound?
What instrument can make any sound? What instrument can make any sound and be heard but not touched or seen? Your voice. What are examples of idiophones? Idiophones make their sound by hitting, rubbing or shaking. Drums are not idiophones. Neither are stringed instruments. Examples of idiophones include the triangle, wood block, maracas, bell, and […]
How do you convert temperature to heat?
How do you convert temperature to heat? When heat transfer is involved, use this formula: change in temperature = Q / cm to calculate the change in temperature from a specific amount of heat added. Q represents the heat added, c is the specific heat capacity of the substance you’re heating, and m is the […]
What happens to pressure if volume decreases in gas?
What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
