Which two factors affect the speed at which a sound wave will travel? The two factors that affect the speed of sound are the medium it is traveling through and the temperature of the medium. What two factors affect speed? Chapter 19 – Motion Question Answer What two factors determine speed? distance & time What […]

Which is better RGB or RYB? RGB are the primary colors of light, since it is additive, meaning the more you add, the closer you get to white. RYB are the primary colors of paint, since it is subtractive, meaning the more you add, the closer you get to black. How do you get white […]

What is normal inHg? A barometric reading in the range of 29.80 and 30.20 inHg can be considered normal, and normal pressure is associated with steady weather. If the reading falls between 29.80 and 30.20 inHg (100914.4–102268.9 Pa or 1022.689–1009.144 mb): Rising or steady pressure means present conditions will continue. Why do we measure air […]

Did Marie Curie find a cure for cancer? Marie Curie, along with her husband Henri Becquerel, discovered radioactivity; a finding that paved the way for both the diagnosis (via X-rays) and treatment of cancer (radiation therapy) in medicine. Did Marie Curie help cure cancer? Marie Curie has left a great deal to the world. Her […]

What is the most likely source of nutrient pollution? The primary sources of nutrient pollution are fertilizer, animal manure, sewage treatment plant discharge, detergents, storm water runoff, cars and power plants, failing septic tanks and pet waste. What are the three major sources of nutrient pollution listed on the webpage? The primary sources of nutrient […]

What is the acceleration of 10 kg? 2m/s2. What is the relationship between acceleration and mass of a body and force and acceleration? The relationship between mass and acceleration is described in Newton’s Second Law of Motion. His Second Law states that the more mass an object has, more force is necessary for it to […]

What is the frequency range of a microwave? Microwave frequencies range between 109 Hz (1 GHz) to 1000 GHz with respective wavelengths of 30 to 0.03 cm. What can interfere with 2.4 GHz? Baby Monitors, Walkie-Talkies and Other Radios Do you have baby monitors, walkie talkies, or maybe a radio locator to keep track of […]

Is angular momentum proportional to radius? Angular momentum of an object with linear momentum is proportional to mass, linear velocity, and perpendicular radius from an axis to the line of the object’s motion. Is angular momentum an axial vector? Axial vectors are those vectors that represent rotational effect and act along the axis of rotation. […]

How do you increase the density of a solid? Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume. What is the effect on the density of solid? When a substance […]
