A piece of copper of mass 120g is heated in an enclosure to a temperature of 125 degree celsuis. it is then taken out of the enclosure and yeld in air for half a minute and dropped carefully into a copper calorimeter of mass 105g containing 200g of water at 20 degree Celsius. calculate the rate at which heat is being lost from the copper when it is held in air. shc of copper is 400

If an object with an initial temperature of 300 k increases its temperature by 1°c every minute, by how many degrees fahrenheit will its temperature have increased in 10 minutes? (a) 6°f (b) 10°f (c) 18°f (d) 30°f

Talia is manufacturing rolls of wire for hanging pictures. she needs a material that is so that it can easily be pulled into wire without breaking.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
