Aparticular instruction set architecture (isa) has four classes of instruction: load/store, fixed-point, floating-point, and branching. load/store instructions all require 2 clock cycles to execute, fixed-point instructions all execute in one clock cycle, floating-point instructions all require 8 clock cycles to execute, and branch instructions take one clock cycle if the branch is successful and two clock cycles if the branch fails. a program is run on a processor with this isa and measurements show that 20% of the instructions executed are load/store, 50% are fixed-point, 5% are floating-point, and the remainder are branches. just 15% of the branches fail. what is the average number of clock cycles per instruction?

An object has a weight of 500 on earth what is the mass of this object

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
