Which condition would be equivalent to an air temperature of 45°F, a wind speed of 30 mi/hr, and a wind-chill equivalent temperature of 15°F? a. a 30°F air temperature and 45 mi/hr winds b. a 30°F air temperature and 15 mi/hr winds c. a 15°F air temperature and 0 mi/hr winds d. a 15°F air temperature and 30 mi/hr winds

B) as the temperature increases, the kinetic energy of the particles increases.|-/

Im not from america so could you explain what route 70 is? how much km or miles does it have? am i supposed to know ,from this text,what the s(road) is? how many km or miles it has?

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
