ELEN [110]1 year ago

When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.

Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.

Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.

There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.

It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

djyliett [7]

Answer:

The correct answer is case-control study.

Explanation:

In a case-control study, two groups of the population are used, in which one group is kept as control, and the other is known as the experimental group that encounters with a specific disease or an outcome. With the help of this study, one can expose the groups to various or single outcomes.  

In the given case, a study is done in which an advertisement on a ban on smoking is encouraged by the non-smokers at the alcohol sale points but not by smokers, in the process a random digit dialing method was used. This random digit dialing method is an illustration of a case-control study, in which the survey of the individuals is done regarding the ban on smoking.

When the football is snapped, which player will have the smallest change in kinetic energy?
DanielleElmas [232]
When you are finding the kinetic energy, it is best to keep this formula in mind.

Ek = 1/2mv²

Where m is mass and v is velocity. Basically sub the numbers in to find the kinetic energy for each. In this case, subbing all the numbers, the smallest change in kinetic energy is the Lineman with a kinetic energy of just 540N.

Of the following phyla, which are non-seed producing and non-vascular?
Masteriza [31]

Answer:

Anthocerophyta, Bryophyta, Hepatophyta.

Explanation:

Non vascular plants are defined as the plants which contains phloem, and xylem without the vascular system. They are containing simpler tissues which are specialized for internal transport of water.

They include bryophyta, hornworts (anthocerophyta), liverworts (hepatophyta) mosses, and some algae. Non vascular plants reproduce with the help of spores, and do not produce fruit, and flowers.
