Meg has two glasses of grape juice. Glass A has 80 grams of juice at 30 °C. Glass B has 80 grams of juice at 50 °C. Which of the following steps will make the kinetic energy of the molecules of the juice in both glasses equal?
Decrease the temperature of juice in Glass A by 20 °C
Increase the temperature of juice in Glass A by 20 °C
Decrease the temperature of juice in Glass B by 30 °C
Increase the temperature of juice in Glass B by 30 °C

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.
