An insulated container has 1.40 kg of water at a temperature of 62.0°C. The temperature of a 700-g copper block is 24.0°C. We drop the block into the water and wait until thermal equilibrium is established. Assume that the amount of heat lost to the container and the surroundings is negligible. Take the specific heats of copper and water to be 385 J/kg K and 4180 J/kg K, respectively. (a) Determine the final temperature of the water. D.

A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d = 21.0 m at 8, 26.0 from the tree then turned and traveled de 11.0 m at 0₂= 140". Meanwhile, the i sister traveled ds = 17.5 m at an angle of 0-117 from the tree. The angles are given with respect to east with counterclockwise being defined as positive(Eigure 1) Figure d₁ 8₂ 1 of 4) > Part C-Distance to home After the boy has found his sister, they want to travel the shortest path home. If their home is located d, 75 m due north of the big treo, what is the magnitude and direction of the displacement from the siblings to their home, dpcH?(Eigure 4) Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis. ▸ View Available Hint(s) dBGH 0BGH Submit 195| ΑΣΦ. Η vec Review noturn to Assignment Provide…
