What occurs when thermal energy is moved from one place to another
sveta [45]
Heat can be moved from one place to another by 3 methods: cunduction, which happends in solids, convection, which happends in fluids, and radiation. Conduction occurs when two objects are touching each other. Heat moves from the hot object to the cold object until the two objects are the same temperature. Convection happends when hotter areas of a liquid or gas rise to the colder areas. Both conduction and convection require some form of matter but radiation does not. Radiation does not rely on things in contact with a heat source and what is being heated. For example, we feel the sun everyday and it feels hot but we never touch it.

Select the correct answer.
joja [24]

Answer:

D. 21/2

Step-by-step explanation:

We simply have to evaluate the first three terms based on the progression's formula:

t= 1,  the first term is 8, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{1-1} = 8 * 1 = 8

t=2, the second term is 2, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{2-1} = 8 * \frac{1}{4} = 2

t=3, the third term is 1/2, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{3-1} = 8 * \frac{1}{16} = \frac{1}{2}

The sum of the first 3 terms is then: 8 + 2 + 1/2 = 10 1/2

Among the answer choices, D. 21/2, which is 10 1/2.

Which equation has a graph that goes through the points (4, -6) and (0, 6)?
Ugo [173]

Answer:

y = -3x + 6\\

Step-by-step explanation:

Find the gradient of the equation

\frac{Difference in y}{Difference in x} \\\\\frac{6 - - 6}{0 - 4}  = \frac{12}{-4} = -3

The equation will have the gradient -3x

Use the general equation of a line, and substitute the coordinates in to find the y-intercept.

y = x + c\\ y = -3x + c\\

(4, -6)

-6 = -3(4) + c\\ -6 = -12 + c\\ -6 + 12 = c\\ c = 66 = -3(0) + c\\ 6 = 0 + c\\ c = 6

(0, 6)

6 = -3(0) + c\\ 6 = -0 + c\\ c = 6

The equation of the line is

y = -3x + 6\\
