chart

autumn 50 kg 4 m/s

mohammed 57 kg 3 m/s

lexy 53 kg 3 m/s

chiang 64 kg 5 m/s

which statement is supported by the information in the chart?

autumn has more kinetic energy than chiang.

mohammed has less kinetic energy than autumn. this is the answer. i got tiered of waiting

lexy has more kinetic energy than mohammed.

chiang has less kinetic energy than lexy.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Which sound characteristic is not affected by the relative motion of an object

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
