copper calorimeter weighs 100g when emptied ,400g when half filled of water at 0°c, and 450g when iced at 0°c is added. when some stem passed into the mixture ,its temperature is rised by 10°c Find the quantity of stem added.(specific latent hear of fusion of ice=3.36×10⁵j/kg

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

well clustered together.
