bicyclists, starting at the same place, are riding toward the same campground by different routes. One cyclist rides 1170 m due east and then turns due north and travels another 1580 m before reaching the campground. The second cyclist starts out by heading due north for 1880 m and then turns and heads directly toward the campground. (a) At the turning point, how far is the second cyclist from the campgroun

Which atomic model was proposed as a result of j. j. thomson’s work?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
