A metal bar in a low temperature physics experiment with mass m = 93 kg had its temperature raised from T1 = 28 K to T2 = 47 K. The metal bar has a specific heat that is a function of temperature: c(T) = A + αT, where A = 430 J/(kg⋅K) and α = 10.2 J/(kg⋅K2). Note the metal bar does not change in volume as it is heated.

Cin carbonh in hydrogeno in oxygen

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
