A metal sheet of cron has an area of 2cm? at a temperature of 15°C. if it is heated to a temperature of 85°C, what will be its final area at 85°C, what will be its final area at 85C7 (B=
2.4x10-51/co)

What is the final velocity of the initial velocity of 25 and -50?

Which of the following are guidelines to follow for obtaining accurate observations

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
