How does volume affect rms speed? Since the temperature is remaining constant, the average kinetic energy and the rms speed remain the same as well. The volume of the container has decreased, which means that the gas molecules have to move a shorter distance to have a collision. What is the rms speed? The root-mean-square […]

Who invented the zodiac?
Who invented the zodiac? Babylonians Are there 12 or 13 zodiac signs? Earth actually travels through 13 signs, including Capricorn, Aries, and, yes, Ophiuchus, but some 3,000 years ago the Babylonians—not NASA—decided 12 was neater than 13, so excluded the 13th zodiac sign and divided the zodiac into 12 parts based on the 12 months […]
Do longitudinal waves have nodes?
Do longitudinal waves have nodes? Longitudinal wave – a wave that is propagated in the same direction as the displacement of the transmitting medium. Node – A node is a point along a standing wave where the wave has zero amplitude. A wave center is stable at the node of the standing wave. What is […]
What are the causes of shortage of electricity?
What are the causes of shortage of electricity? There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Why electricity is harmful? […]

How might predator/prey relationships affect light pollution?
How might predator/prey relationships affect light pollution? Summary: A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance. When the environment has reached its carrying capacity for the human population […]
Is nitrous acid present in acid rain?
Is nitrous acid present in acid rain? Industrial areas tend to release nitrous oxides gas, or chlorine gas or sulfurous gas into the atmosphere, when these gases combine with water from the acid rain, they are turned to nitric acid (HNO3), chloric acid (HCl) or sulfuric acid (H2SO4) respectively. Is sulphurous acid present in acid […]
What is an experimental control example?
What is an experimental control example? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. Why is it important to have […]
What are five differences between plant and animal cells?
What are five differences between plant and animal cells? A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds […]
