A laptop computer communicates with a router wirelessly, by means of radio signals. The router is connected by cable directly to the internet. The laptop is 8.9 m from the router, and is downloading text and images from the internet at an average rate of 160 Mbps, or 160 megabits per second. (A bit, or binary digit, is the smallest unit of digital information, 1 megabit per second is 1x106 bits per second.) On average, how many bits are downloaded to the laptop in the time it takes the wireless signal to travel from the router to the laptop?

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
