Can solids undergo convection

1 answer:

5 0

No because solids can't transmit heat by convection, and convection only works because of hotter and quicker moving molecules have a lower density so they rise to the surface. But in a solid, the molecules can't move relative to each other. They only vibrate :)

I need help on this problem! g(h+2/3)=1 for h

Tju [1.3M]

Answer:

$g(h + \frac{2}{3} ) = 1 \\ \\ gh + \frac{2}{3} g = 1 \\ \\ gh = 1 - \frac{2}{3} g \\ \\ h = (1 - \frac{2}{3} g ) \div g \\ \\ h = (1 - \frac{2}{3} g ) \times \frac{1}{g} \\ \\ h = \frac{1}{g} - \frac{2}{3}$

I hope I helped you^_^

Answer:

2x² - 3x - 2

Explain:

Use the FOIL method: (a +b)(c +d) = ac + ad +bc +bd.

2x² + x - 4x - 2

Collect like terms.

2x² + (x - 4x) - 2

Simplify.

2x² - 3x - 2

Andy wrote the following statement:

olasank [31]

I believe it would be B. Because, an isoceles triangle is a triangle with 2 equal sides and 1 is not equal ... SO, more than one triangle could be drawn from this information. Because, 55 could be the uneven side for many triangles. So, B. Andy is incorrect, because more than one triangle can be drawn from the given info. :)

B. Hope it helps!!! :)
