Avolume of 125 ml of h2o is initially at room temperature (22.00 ∘c). a chilled steel rod at 2.00 ∘c is placed in the water. if the final temperature of the system is 21.30 ∘c , what is the mass of the steel bar? use the following values: specific heat of water = 4.18 j/(g⋅∘c)specific heat of steel = 0.452 j/(g⋅∘c)express your answer to three significant figures and include the appropriate units. mass of the steel =

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
