Beta angle in the Earth's shadow, and results in extremely reduced absorption of solar energy. At a LEO of 280 kilometers, the object is in sunlight through 59% of its orbit (approximately 53 minutes in Sunlight, and 37 minutes in shadow.) On the other extreme, an object launched into an orbit parallel to the terminator results in a beta angle of 90 degrees (formula_2 = 90°), and the object is in sunlight 100% of the time. An example would be a polar orbit initiated at local dawn or dusk on an equinox. Beta angle can be controlled to keep a satellite as
Less-is-better effect of top-quality candy than a box containing those 24 pieces plus 16 lower-quality pieces. If a manufacturer has developed two versions of a product and wishes to know which will be more popular with consumers and should therefore be put on the market, presenting them jointly to the public will enable consumers to evaluate differences between them, while presenting them separately will better predict the consumer's actual experience of the product when and if it is actually put on sale. Less-is-better effect The less-is-better effect is a type of preference reversal that occurs when the lesser or smaller alternative of
