Question 17 2 pts A major advantage of direct mapping of a cache is its simplicity. The main disadvantage of the organization is that it does not allow simultaneous access to the intended data and its tag its access time is greater than that of other cache organizations the cache hit ratio is degraded if two or more blocks used alternatively map onto the same block frame in the cache. it is more expensive than other types of cache organizations the number of blocks required for the cache increases linearly with the size of the main memory.

M3. A student conducts an investigation into the motion of a car that accelerates from rest on a straight, level roadway. A driver operating the car causes the car to speed up from rest at time $ t $ $ =0 $ and the student makes measurements of the distance traveled and the speed of the car every second. What experimental evidence would support the conclusion that the car's acceleration is uniform? Select two answers. (A) All objects released from rest at the same time fall together. (B) The distance fallen is proportional to the square of the falling time. (C) A graph of velocity vs. time is linear. (D) Objects speed up as they free-fall.
