A train has to negotiate a curve of 400m radius. By how much should the outer rail be raised w. r.t the inner rail for a speed of 48km/h ?The distance between the rail is 1m.

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.

It indicates no change in temperature and the process of matter changing its state

He can play two games. 13/4=3.253.25*2=6.5

Sorry i don’t know what to do
