Answer:
So we need to add 13.46 gr of ice in order to reach the final equilibrium temperature of 49 C
Explanation:
For this case we need to use the fact that the sum for all the heats involved in the system are 0, since we assume an equilibrium state.
Data given
mass of the porcelain cup
the specific heat for the porcelain cup
initial temperature for the coffee and the porcelain cup.
Volume of the coffee.
We can convert this to m^3 and we got 0.000161m^3 and assuming the density fot the coffee equal to the water 1 Kg/m^3 the mass would be:
Specific heat for the coffee
mass of ice required
equilibrium temperature
represent the latent heat of fusin since the ice change the state to liquid.
Solution to the problem
Using this formula:
We have this:
Now we can replace and we have this:
And now we can solve for and we have:
So we need to add 13.46 gr of ice in order to reach the final equilibrium temperature of 49 C
Answer:Probably water ballons,Paint,Etc
Explanation:
Venus is the second planet from the sun. It is usually the brightest object in our sky, other than our sun and moon. At sunrise and sunset, it looks like a big, bright star. It is bright because Venus has a cloud cover that reflects the sunlight. These clouds are made up of gases.

Answer:
I'M SORRY I CAN'T SEE THE PICTURE BUT IT WILL MOST LIKELY BE THE DIFFERENCE BETWEEN THE NUMBERS
Explanation:
for instance if there was someone pushing a desk with a net force of 9 towards the right, the net force would come to a total of 9 since there is no one on the other side pushing the desk. Meaning the desk would go right. I'm sorry if this isn't what you needed D:
