Which material does sound travel fastest through? How fast speed travels, or the speed of sound, depends on the kind of matter it is moving through. Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Can you hear sounds better […]
What is standard takeoff minimums?
What is standard takeoff minimums? As a quick reminder, standard takeoff minimums for one and two engine airplanes is 1-mile visibility and a 1/2 mile visibility for 3-4 engine airplanes. How do you find alternate minimums? To view the non-standard IFR alternate minimums information, you will need to go to the Airports page > search […]
Do light bulbs have high or low resistance?
Do light bulbs have high or low resistance? Incandescent light bulbs have a small filament which when heated begins to glow and emit light. The reason the filament heats up is because it has a high resistance, which means that as electrons move through the filament, they lose a lot of energy. Does a brighter […]
Which of the following are characteristics of a generalist species?
Which of the following are characteristics of a generalist species? A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions […]

What are some good insulators?
What are some good insulators? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of […]
What comes through nuclear pores?
What comes through nuclear pores? Each nuclear pore is a large complex of proteins that allows small molecules and ions to freely pass, or diffuse, into or out of the nucleus. Similarly, RNA transcribed in the nucleus and proteins that are destined to enter the cytoplasm have nuclear export sequences that tag them for release […]
How can I tell if my glass is heat-resistant?
How can I tell if my glass is heat-resistant? If it is a heat-resistant glass, there will generally be a corresponding label on the glass, indicating the temperature and range of use; If you find nominal Pyrex glass at a low price, consider its authenticity. Is all glass heat-resistant? Glass is thermal-shock resistant, meaning it […]
Does the amount of solvent change when you dilute a solution?
Does the amount of solvent change when you dilute a solution? 1. Learn how to dilute and concentrate solutions. Often, a worker will need to change the concentration of a solution by changing the amount of solvent. Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. What is […]
Why did F1 stop using slicks?
Why did F1 stop using slicks? Formula 1 got rid of the ‘slicks’ and re-introduced ‘grooved’ tyres. The sole purpose of the move was to curb the increasing cornering speeds. Those grooved tyres had three parallel grooves in the front tyres and four parallel grooves in the rear tyres. Are F1 Tyres smooth? ‘Slick’ tyres […]
