Answer:
2. The star is a member of binary eclipsing star system.
Explanation:
The question above shows an example of an eclipsing binary star. This type of star is very variable because the intensity of its brightness varies in the deccore of a few hours. This is because these stars are so close to an observer's field of view on the Earth's surface that they are easily eclipsed, and it is exactly these eclipses that cause the brightness of these stars to vary, which undergo a constant period of approximately 73 hours. intense shine, followed by constant drops in the intensity of that shine (lasts about 2 hours).
Answer:
D. the greater the availability of close substitutes.
Explanation:
Price elasticity of demand is a measure of the sensitivity of demand for a good or service to changes in the price of that product. We say that the price elasticity of demand is elastic when a percentage change in the price of this good has major impacts on demand. On the contrary, we say that the price elasticity of demand is inelastic when variations in the price of goods have little or no influence on demand.
Goods that are inelastic in demand are usually consumer-essential goods for which there are few substitution options, such as a cancer drug. On the contrary, elastic goods are those whose price variations diminish the demand for a range of substitute goods. For example, if the price of rice goes up, people may demand spaghetti, which is a substitute good.Therefore, goods with a large number of substitutes tend to have price elastic demand.
That statement is false
