Examples of static contrast ratio in the following topics:
-
- The retina of human eye has a static contrast ratio of around 100:1 (about 6.5 f-stops).
- Hence, a dynamic contrast ratio of about 1,000,000:1 (about 20 f-stops) is possible.
-
- Pascal's Principle states that pressure is transmitted and undiminished in a closed static fluid.
- Pascal's Principle (or Pascal's Law) applies to static fluids and takes advantage of the height dependency of pressure in static fluids.
- As a result of Pascal's Law, the pressure change (pressure applied to the static liquid) is transmitted undiminished in the static liquid so that the applied pressure is 2 N/m2 at the bottom of the bottle as well.
- For a hydraulic press, the force multiplication factor is the ratio of the output to the input contact areas.
- Two different types of hydraulic press configurations, the first in which there is no difference in height of the static liquid and the second in which there is a difference in height Δh of the static liquid.

- The receivables turnover ratio measures how efficiently a firm uses its assets.
- The receivables turnover ratio, also called the debtor's turnover ratio, is an accounting measure used to measure how effective a company is in extending credit as well as collecting debts.
- The receivables turnover ratio is an activity ratio, measuring how efficiently a firm uses its assets.
- A high ratio implies either that a company operates on a cash basis or that its extension of credit and collection of accounts receivable is efficient; in contrast, a low ratio implies the company is not making the timely collection of credit.
- Sometimes the receivables turnover ratio is expressed as the "days' sales in receivables":
-
- The acid-test ratio, also known as the quick ratio, measures the ability of a company to use its near cash or quick assets to immediately extinguish or retire its current liabilities.
- The acid-test ratio, like other financial ratios, is a test of viability for business entities but does not give a complete picture of a company's health.
- In contrast, if the business has negotiated fast payment terms with customers and long payment terms from suppliers, it may have a very low quick ratio yet good liquidity .
- A low acid-test ratio may be a sign of poor use of cash by a business.
- The acid-test ratio is similar to the current ratio except the value of inventory is omitted from the calculation.
-
- For "ideal" flow along a streamline with no change in height, an increase in velocity results from a decrease in static pressure.
- The kinetic energy of the fluid is stored in static pressure, $p_s$, and dynamic pressure, $\frac{1}{2}\rho V^2$, where \rho is the fluid density in (SI unit: kg/m3) and V is the fluid velocity (SI unit: m/s).
- The SI unit of static pressure and dynamic pressure is the pascal.
- Static pressure is simply the pressure at a given point in the fluid, dynamic pressure is the kinetic energy per unit volume of a fluid particle.
- The Mach number represents the ratio of the speed of an object moving through a medium to the speed of sound in the medium.
-
- In finance, the Acid-test (also known as quick ratio or liquid ratio) measures the ability of a company to use its near cash or quick assets to extinguish or retire its current liabilities immediately.
- A company with a Quick Ratio of less than 1 cannot pay back its current liabilities.
- Acid test often refers to Cash ratio instead of Quick ratio: Acid Test Ratio = (Current assets - Inventory) / Current liabilities.
- Note that Inventory is excluded from the sum of assets in the Quick Ratio, but included in the Current Ratio.
- In contrast, if the business has negotiated fast payment or cash from customers, and long terms from suppliers, it may have a very low Quick Ratio and yet be very healthy.

- The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field.
- Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles.
- Mass analyzers separate the ions according to their mass-to-charge ratio.
- The deflections of the particles are dependent on the mass-to-charge ratio.
- This one is for the measurement of carbon dioxide isotope ratios (IRMS) as in the carbon-13 urea breath test.
-
- Most European nations are examples of countries at the end of the demographic transition: both birth and death rates are low, so populations are static or shrinking.
- By contrast, in countries with underpopulation there are often insufficient labor pools to support economic growth, but employment tends to be stable.
- In other words, it is a ratio—population:resources.
-
- This contrasts with the balance sheet, which represents a single moment in time.
- Price to Earnings Ratio = Market Value of Stock / Earnings per Share
- A higher P/E ratio means that investors are paying more for each unit of current net income, so the stock is more "expensive" than one with a lower P/E ratio.
- The P/E ratio can be regarded as being expressed in years.
- The ratio does not factor in expansion or debt repayment.
-
- The dividend-price ratio is a company's annual dividend payments divided by market capitalization, or dividend per share divided by the price per share.
- The dividend yield or the dividend-price ratio of a share is the company's total annual dividend payments divided by its market capitalization, or the dividend per share, divided by the price per share.
- Its reciprocal is the Price/Dividend ratio.
- The yield is the ratio of the annual dividend to the current market price, which will vary.
- In contrast, some investors may find a higher dividend yield unattractive, perhaps because it increases their tax bill.
