What is the formula for diffusion? rate(gas A) × √molar mass(gas A) = rate(gas B) × √molar mass(gas B) This means that the relative rate of diffusion of two gases can be used to determine their relative molecular mass (or molar mass). Which gases will have the slowest effusion rate? Three gases were used: hydrogen, […]
Which plants grow very low to the ground and have no true roots and no true leaves?
Which plants grow very low to the ground and have no true roots and no true leaves? Mosses are typically soft plants that grow in clumps or mats. Like other plants, they produce chlorophyll and undergo photosynthesis, but they do not have true roots. They instead have multicelled, rootlike appendages called “rhizoids,” which anchor the […]
Is the Ncvs reliable?
Is the Ncvs reliable? Research based on interviews of victims obtained from police files indicates that assault is recalled with the least accuracy of any crime measured by the NCVS. What are the limitations of the Ncvs? A limitation of the NCVS data stems from the fact that they are derived from a sample. Like […]
What temperature is air most dense?
What does the dashed line separating the two sides represent?
What does the dashed line separating the two sides represent? What does the dashed line in the beaker separating the two sides represent membrane potential? Explanation: Membrane Potential: A gradient is membrane, through which the different molecules move from one portions of the body or system into the another. What is an example of osmosis […]
On what principle is an AC generator based?
On what principle is an AC generator based? AC generators work on the principle of Faraday’s law of electromagnetic induction which states that electromotive force -EMF or voltage – is generated in a current-carrying conductor that cuts a uniform magnetic field. What is generator working principle? Electric generators work on the principle of electromagnetic induction. […]
Why is motion in one dimension the simplest form of motion?
Why is motion in one dimension the simplest form of motion? 2.0 One-Dimensional Motion One-dimensional motion means moving forwards and/or backwards along a straight line, and is the simplest form of motion to study. The core of learning this is understanding rates, which is how any quantity changes over time. Key rates we will study […]
Is the image real or virtual erect or inverted?
Is the image real or virtual erect or inverted? Real images (images on the same side of the object) are always inverted. Virtual images (images on opposite side of an object) are always erect/ upright. How do you tell if an image is real or virtual? (You will have no trouble remembering this if you […]
Do birds feel earthquake while flying?
Do birds feel earthquake while flying? Birds and animals “feel” things in more dimensions than humans do. Birds for example are very sensitive to magnetic fields. Earthquakes being tectonic activity, I can’t see how it won’t have small impact on the earth’s magnetic field in the region. This could in turn be felt by the […]
How the mind and body are connected?
How the mind and body are connected? The brain and body are connected through neural pathways made up of neurotransmitters, hormones and chemicals. These pathways transmit signals between the body and the brain to control our everyday functions, from breathing, digestion and pain sensations to movement, thinking and feeling. What three levels did Plato say […]
