Answer:
(1.9756, -2.1951)
Explanation:
The center of mass equation is: = , where m represents the masses and x represents the position.
In order to find the coordinates of the center of mass, we need to use this equation for both the x-values and the y-values.
<u>x-values:</u>
<u /> = = = = = 1.9756
<u>y-values:</u>
<u /> = = = = = -2.1951
<u>center of mass:</u>
(1.9756, -2.1951)
Answer:
15.65 °C
Explanation:
cold temperature (Tc) = -15.5 degree C = 273.15 - 15.5 = 257.65 kelvin
minimum coefficient of performance (η) = 8.25
find the maximum hot reservoir temperature of such a generator (Th)
η = \frac{Tc}{Th-Tc}
Th = Tc x (\frac{1}{η} + 1)
Th = 257.65 x (\frac{1}{8.25} + 1)
Th = 288.8 K
Th = 288.8 - 273.15 = 15.65 °C
Answer:
what?
Explanation:
i have no idea what u talking about.
Answer:
Probably float, but then sink after a while
Explanation:
im not an expert about these topics but I think it will float for a while until the water soaks into the wood causing the wooden cube to sink. Sorry if it's wrong, just what I think
Answer:
Thus simply tells us that The nut has no net charge and so therefore, There will be a negative charge on the left side, and an equal positive charge on the right side
