Aman takes a brick out of the fire when it's at 285 degree celsius, he drops it in a bucket of water. then covers the bucket. the bucket and cover are made of an insulating material. the bucket contains 2.6 kg of ice originally at -5 degree celsius. the 1.3 kg brick is made of iron .which has a specific heat of 448j/kg degree celsius. lets find out the temperature of brick and water once equilibrium is reached. specific heats of ice , liquid water, steam are 2090,4186,1970 respectively

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.

Current vs. forcewhat type of relationship does this graph show?

Roberto and laura are studying across from each other at a wide table. laura slides a 2.2 kg book toward roberto. if the net force acting on the book is 1.6 n to the right, what is the book acceleration
