Your bedroom gets direct sunlight through a window during the hottest part of the day. You ask your mom to turn down the thermom
ycow [4]
I want to say its cooled by reflection because of the foil, sun reflects off of the foil back into the atmosphere. I don't think it's conduction because I have the foil on my windows and it's never warm to the touch. it's not a liquid so I don't believe it's convection. The foil reflects the radiation so I don't think it's b, c or d. so I wanna say A but I'm not 100% sure

A certain comet has a parallax 1/40 as large as the moon. How far away is it (compared to the Moons distance)? Show Work
Ad libitum [116K]
The distance and parallax are inversely related. We can find the distance using the following equation:

d= \frac{1}{p}

where d is distance and p is parallax.

We are given the parallax of the comet relative to the moon, and we are looking for the distance to the comet relative to the moon's distance, so wee can plug in the following value:

d= \frac{1}{ \frac{1}{40} }

The distance is 40 times as far away as the moon.

PAGE NO.: DATE: Why does heat flow from higher temperature to lower temperature body? ​
salantis [7]

Answer:

The atoms of the system with higher temperature will gain the heat energy and the vibration of these atoms will increase. The atoms or molecules on the system with lower temperature have lower temperature and are not vibrating. ... So, we can say that heat always flows from higher temperature to a lower temperature.
