Theritical MM/ Observed MM = 1 + a (2-1)
58.5/30 = 1+a
a = .95 or 95%

The apparent size of an object is determined by the size of its image on?
The retina
Is the apparent molecular weight of air at elevation same as at sea level?
The apparent molecular weight of a mixture of ideal gases depends on the concentrations of such gases in the Atmosphere. Below 100km altitude the gases in the atmosphere are very well mixed so that the concentration of all the gases does not vary (approximately) with altitude. Therefore the apparent molecular weight would not vary very much at an elevation and at sea level.
Is rounded quartz crystal in sandstone considered a mineral?
Yes. While the crystal form is not apparent, there is still a crystalline structure on the molecular scale.
How do you measure the distance to a cepheid?
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

What is apparent solar time determined by?
Its position and apparent movement around the sky. "Apparent solar time" is based on the "apparent solar day", reckoned by defining as 'solar noon' the moment of the Sun's highest altitude above the horizon on any given day. (That's when the Sun crosses the observer's meridian.) Apparent solar days do not have the exact same length (from one solar noon to the next) throughout the year, which is surprising to some at first. This is why the first approaches to creating a solid "standard time" involved determining the length of the 'mean solar day' (average solar day).

What characteristic of a star is determined by its distance from the observer?
It's apparent size, heat, and gravitational force.

Does depression only occur when bad things happen?
No, that type of depression is called Reactive Depression.Major Depression, Dysthymia (mild depression), and the Depression Phase of Bipolar Disorder can strike entirely "out of the blue" for no apparent external reason. They may or may not have external triggers, but the trigger if there is one can as easily be mood incongruent (good events trigger depression) as mood congruent (bad events trigger depression).
Would experimental procedures for apparent molecular weight of air calulations work for pure gas?
Yes, absolutely - experimental work is based opon highly controlled flexbility.
How do you make depression better?
There are basically two types of depression. If you have depressing circumstances in your life (a failing marriage, bankruptcy, etc.) you can understandably react to them by becoming depressed, which is known as reactive depression. That is not a psychiatric problem, it is a problem in managing your life, and the solution to the depression is to solve the problems that are making you depressed. The other kind of depression has no apparent cause in the circumstances of your life, and is related to brain chemistry. That is a psychiatric problem and it can be successfully treated by the use of antidepressants.
What are some health risks of being overweight?
The two biggest risks are diabetes and heart disease. There are other risks that may not be as readily apparent and one of them would be depression.
What is a reaction in which a gas a solid precipitate or a molecular compound is formed from the apparent exchange of inns between two compounds?

Where can one perform online a depression self test?
If the desire to complete a depression self test becomes apparent, these tests can be found on many of the health related associations and websites. The NHS direct if not hosting a test themselves will contain all the information required to locate a test online.
Was Sylvia Plath's depression apparent in her poems?
Yes, Sylvia Plath's struggles with depression are evident in her poetry through themes such as despair, melancholy, and introspection. Her works often reflect a deep sense of emotional turmoil and psychological pain, providing insight into her personal struggles with mental health.
