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 […]
Where is basalt commonly found?
Where is basalt commonly found? It is found all over Earth, but especially under the oceans and in other areas where Earth’s crust is thin. It formed in the Isle Royale-Keweenaw region because of the Midcontinent Rift. Most of Earth’s surface is basalt lava, but basalt makes up only a small fraction of continents. What […]
What is the formula for diffusion?
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, […]
How do you locate the epicenter?
What temperature is air most dense?
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 […]
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. […]
What are the negative effects of gamma rays?
What are the negative effects of gamma rays? The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. How can we reduce exposure to gamma rays? […]
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 […]
