What is the formula for vector? The direction of a vector is the measure of the angle it makes with a horizontal line . tanθ=y2 − y1x2 − x1 , where (x1,y1) is the initial point and (x2,y2) is the terminal point. Example 2: Find the direction of the vector →PQ whose initial point P […]
What are examples of analog?
What are examples of analog? Analog Signals photocopiers. old land-line telephones. audio tapes. old televisions (intensity and color information per scan line) VCRs (same as TV) What is the first step in the analog to digital conversion process? The first step is to take a look at the two fundamental processes involved during the analog-to-digital […]
What is the lift formula?
What is the lift formula? The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. The combination of terms “density times the square of the velocity divided by two” is called the dynamic pressure and […]
What happens when two or more atoms bond together?
What happens when two or more atoms bond together? Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. A molecule consists of atoms of an element bonded to another atom of the same element. When […]

No matter the size of your enterprise, technology has both tangible and intangible benefits that will help you make money and produce the results your customers demand. Technological infrastructure affects the culture, efficiency and relationships of a business. Is technology good for relationships? […]
What is the density of the inner planets?
What is the density of the inner planets? By matching the Measured Density to the Calculated Density, you are likely to find values similar to the following: Earth has a core filling about 65% of its interior. Venus: 65%, Mars: 40%, Mercury: 80%, The Moon: 40%. Earth has the largest mass and strongest gravity of […]
What do liquid methane and water have in common?
What do liquid methane and water have in common? Answer: Methane on the other hand, is made of one carbon atom and 4 hydrogen atoms. Like water, the bonds are covalent. Because water displays hydrogen bonding with other molecules, a large amount of heat energy is required to break this, and water’s boiling point is […]
What are some positive effects of invasive species?
What are some positive effects of invasive species? The birds that eat the fruit of invasive plants benefit from having an abundant food source in the fall and winter, which increases their survival. Invasive plants can also serve as a source of pollen and nectar for a variety of insect species. What is an example […]
What are the two main factors that affect seawater density?
What are the two main factors that affect seawater density? Sea water has characteristic properties (e.g. density) that are independent of sample size. There are two main factors that make ocean water more or less dense: temperature and salinity. Cold, salty water is denser than warm, fresher water and will sink below the less dense […]
