Only if either demand or supply was either completely elastic or inelastic will the tax burden fall entirely on either the buyer or the seller. Between these 2 extremes, tax incidence varies continuously from a perfectly inelastic supply or perfectly elastic demand, where the sellers assumes the entire burden of the tax to the perfectly elastic supply or perfectly inelastic demand where the buyers bear the entire burden. To better see how the elasticity of supply and demand affects tax incidence, consider a 20% tax on a can of soda. Suppose the government decides that the buyer should pay the 20% tax. Does this mean that the buyers will be paying 20% more, or will sellers have to share some of the tax burden? Since higher prices decrease demand, regardless of the reason for the higher prices, sellers will share some of the burden. How much of the burden will be determined by the elasticity of supply and demand for the product?

Seek time is the time required to move the disk arm to the required track. Rotational delay or latency is the time it takes for the beginning of the required sector to reach the head. Sum of seek time (if any) and latency is the access time. Time taken to actually transfer a span of data is transfer time.

‘Sitting on the fence’ is the correct idiom used. It is used to describe a person’s lack of decisiveness, neutrality or hesitance to choose between two sides in an argument or a competition, or inability to decide due to lack of courage. Thus, the sentence is grammatically and contextually correct. Thus, the correct formation would be, ‘Decide one way or the other; you can’t be sitting on the fence forever’.
