A copper coin with a mass of 6.30 grams changes temperature in the sunshine from 20.0°C to 32.0°C. How much energy is transferred? The specific heat capacity of copper is 0.377 joules/gram degree Celsius. Express your answer to three significant figures.
The amount of energy transferred to the coin is
joules.
Answers
Answer:
q = mC∆T
q = heat = ?
m = mass = 6.30 g
C = specific heat = 0.385 J/g/deg
∆T = change in temperature = 32-20 = 12º
q = ((6.30 g)(0.385 J/g/deg)(12 deg) = 29.1 J (to 3 significant figures)

How are white blood cells linked to the lymphatic system?
Answers
Answer:
The lymphatic system produces white blood cells, known as lymphocytes. There are two types of lymphocyte, T cells and B cells. They both travel through the lymphatic system. As they reach the lymph nodes, they are filtered and become activated by contact with viruses, bacteria, foreign particles, and so on in the lymph fluid.

Match the different methods used for calculating revenue and profit to the formulas used for calculating them. total revenue average revenue marginal revenue gross profit net profit
Answers
Answer:
See explanation below
Explanation:
1) Total Revenue:
Total revenue refers to the total amount of income that is generated when a company sells or offers their service.
It is usually calculated as the product of the product or services sold by the quantity.
It is calculated by ;
TR = Q * P
Where TR = Total Revenue
Q = Quantity
P = Price
2.) Average Revenue:
Average revenue is the revenue gotten by a company per unit of output sold. It is calculated by:
AR = TR / Q
Where AR = Average Revenue
TR = Total Revenue
Q. = Quantity
3.) Marginal Revenue:
This is the net revenue that is generated by selling an additional unit of commodity; which is the change in total revealer unit. It is calculated by:
MR = change in Total Revenue / change in Quantity
Where MR = Marginal Revenue
4.) Gross Profit:
Gross profit is the amount of revenue left after factoring out the cost of production and sales and servicing.
It is calculated by subtracting revenue from the cost of goods sold -
Gross Profit = Revenue - Cost of goods sold
Net Profit:
Net profit is the amount of money a company has left after subtracting all interests, tax expenses and cost.
It is calculated by;
Net Profit = Gross Profit - Expenses

Gerald's science teacher mixed liquid X and liquid Y, both at room-temperature, in a large beaker. two beakers of clear solutions to the left of a right-pointed arrow, and a large beaker with a clear solution to the right of the arrow The mixture in the large beaker still looked clear like water, but when the students, one at a time, carefully touched the outside of the large beaker, it felt warm to the touch. Why did the large beaker most likely feel warm? A. The two liquids were not soluble in water. B. The release of a gas heated the solution. C. A chemical reaction produced a new substance. D. The energy of mixing warmed the liquids.
Answers
Answer:
c
Explanation:
A chemical reaction produced a new substance. In a chemical reaction, the atoms that make up the reactants are rearranged to produce various products.
What is chemical reaction?chemical reaction, the transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances.
A chemical reaction is one in which two or more reactants will react to form a new substance. When new substance will form it will produce heat. Therefore, when science teacher was mixing two liquids it was generating heat.
Heating a substance allow molecules to move faster. When heat is given to the object it will move fast. When heat will apply to a solid it will turn into liquid. When heat is supplied to the liquid it will turn into gas.
Therefore, A chemical reaction produced a new substance. In a chemical reaction, the atoms that make up the reactants are rearranged to produce various products.

A solution of 12M HCl is diluted so that it goes from 550mL to a total volume of 1000mL. What is the new concentration of the solution?
Answers
Answer:
6.6M
Explanation:
C=concentration
V=Volume
C1V1=C2V2
rearrange formula to find C2
(C1V1)/V2= C2
(12M x 550mL)/1000mL= C2
6600M*mL*/1000*mL* =C2 (cancel units)
6.6M=C2

Mg electron configuration: [Ne]3s2
Ca electron configuration: [Ar]4s2
Ar electron configuration: [Ar]
K electron configuration: [Ar] 4s1
We notice that Ca has two electrons in the 4s sublevel, which satisfies what the question is asking for.

If 0=30° then verify that sin20=2sin0.cos0
Answers
Answer:
It is proved that sin20=2sin0.cos0
Explanation:
Given
[tex]0=30[/tex] °
[tex]sin20=2sin0.cos0[/tex]
Substituting the value of "0" on both the sides, we get -
[tex]sin2 (30) =2sin 30 * cos 30\\sin 60 = 2 * sin 30 * cos 30 \\0.866 = 2 * 0.5 * 0.866\\0.866 = 0.866[/tex]
Since LHS = RHS
we can say that [tex]sin20=2sin0.cos0[/tex]
