When the demand for a product is not present yet the product is bought then it is called zero demand...for example - the demand for old newspapers. It may be bought for other purposes and not for reading it or historians and others might buy to read it too.
If demand is zero, then the equilibrium price is zero and it would be unwise to supply such a good or service.
When an increase in income is not associated with a change in the demand of a good.
No, the elasticity of demand can be positive, negative, or zero. It depends on how the quantity demanded changes in response to a change in price.
When the coefficient of price elasticity of demand is zero, it indicates that demand is perfectly inelastic. This means that consumers will purchase the same quantity of a good or service regardless of any changes in its price. In such cases, the quantity demanded remains constant, as the good is considered a necessity with no close substitutes. Examples of perfectly inelastic demand often include essential medications or life-saving products.

Demand is unit elastic.
The two extreme ranges of price elasticity of demand are Zero and Infinity.
Choke price is the maximum price at which the quantity demanded of a good drops to zero. To calculate it, you typically analyze the demand curve for the product, identifying the price point where demand reaches zero. This can often be estimated using demand equations or by observing market behavior. In practical terms, you may set up a linear demand equation and solve for the price when quantity demanded equals zero.

i) "If the demand curve is vertical, elasticity is zero"Price Elasticity of Demand captures the shift in demand for rises in prices in percentage terms. Therefore if a commodity is such that no matter what price the producer charges the consumer has no alternative but to buy it, then for any price the demand for that commodity remains unaltered, maybe an example is a monopolist salt producer. Therefore the demand curve must be vertical, no matter what the price the quantity demanded is same, hence the price elasticity is zero.

No. The more rare a good, and the more demand, the higher the price will be.
Price elasticity of demand= percentage change in demand/percentage cgange in price 2 = % chnge in demand/10 % change in demand= 2*10 % change in demand= 20%
A vertical demand curve represents perfectly inelastic demand, meaning that the quantity demanded does not change regardless of price changes. Consumers will purchase the same amount of the good, regardless of its price, indicating that they have no substitutes or alternatives. In this case, the price elasticity of demand is equal to zero.
