What is the relationship in which the ratio of the manipulated variable and the responding variable is constant group of answer choices? The answer is letter B. When the ratio of the manipulated variable and responding variable is constant, this suggests that as one variable increases, the other variable also increases, and vice versa. This […]
Why is geocentric theory wrong?
Why is geocentric theory wrong? The first big problem with the geocentric model was the retrograde motion of planets like Mars. His model has the planets moving around the Sun in circular orbits. This can explain retrograde motion, but his model doesn’t fit all the planetary position data that well. Is the geocentric theory correct? […]
Does Reynolds number increase with velocity?
Does Reynolds number increase with velocity? An increase in diameter without a change in velocity also increases Re and the likelihood of turbulence; however, the velocity in vessels ordinarily decreases disproportionately as diameter increases. Both factors increase the Reynolds number, which increases the likelihood of turbulence. What is the range of Reynolds Number? Actually, the […]
What kind of bonding is hydrogen peroxide?
What kind of bonding is hydrogen peroxide? CHEBI:16240 – hydrogen peroxide. An inorganic peroxide consisting of two hydroxy groups joined by a covalent oxygen-oxygen single bond. Hydrogen peroxide is a chemical compound with the formula H2O2. In its pure form, it is a very pale blue liquid, slightly more viscous than water. What is the […]
What are the 3 ways energy is used?
What are the 3 ways energy is used? Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. How do we store energy? Energy can be stored in a variety of ways, including: Pumped hydroelectric. […]
Can a direct object be more than one word?
Why is burning coal bad for the environment?
Why is burning coal bad for the environment? The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. Is oil or coal worse for […]
Can you take a picture of an item and find it online?
Can you take a picture of an item and find it online? The Google Goggles app is an image-recognition mobile app that uses visual search technology to identify objects through a mobile device’s camera. Users can take a photo of a physical object, and Google searches and retrieves information about the image. Recognize and offer […]
How do you make a sucrose density gradient?
How do you make a sucrose density gradient? Sucrose density gradient solutions Prepare 150 mL of 1X PE buffer containing 0.1% (w/v) Triton X-100. Prepare the sucrose solutions: To prepare a 20% (w/w) solution: i. Zero a container on a balance. ii. Add 10 g sucrose to the container. iii. Add the PE/Triton solution slowly […]
What happens if the magnetic field flips?
What happens if the magnetic field flips? During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface. How often do poles reverse […]
