SPH4U Physics 12 Communication 3. (4 marks)Two identical balls, A and B, are released from rest on inclines that have the same vertical drop and the same horizontal distance from one end to the other. The inclines differ in detail as illustrated in Figure 3. (Note that very little energy is lost due to rolling friction.) A А (a) Which ball arrives at the end first? Explain your answer. B OD Figure 3 (b) Racing cyclists apply this principle on inclined oval tracks. Explain how.

An fm radio station broadcasts at 9.23 x 107 hz. given that the radio waves travel at 3.00 x 108 m/s, what is the wavelength of these waves?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
