A 130 g sample of brass at 120.0 degrees Celsius is placed in a calorimeter cup that contains 130 g of water at 35.0 degrees Celsius. Disregard the absorption of heat by the cup and
calculate the final temperature of the brass and water. Specific heat of water = 4.18 J/gC,
specific heat of brass=0.380 J/gC. Attach your complete solution

Explanation:

Hello there!

In this case, since we are looking for an equilibrium temperature, we can evidence how the net heat flow is 0 as all the heat released by the hot brass is absorbed by the water:

Thus, by writing that equation in terms of mass, specific heat and temperature we obtain:

Thus, by applying the following algebra, it is possible to arrive to a clean expression to obtain the equilibrium temperature:

Then, by plugging the masses, specific heats and initial temperatures in, we obtain:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
