Answer:
The mass of a dust particle is 7.53 x 10^-10 kg. (Hope it helped.)
Explanation:
Answer:
ΔV= -5.833×10⁻³
Negative sign indicates that volume decreases
Explanation:
Given data
System heat gains Q=3220 J
Pressure P=1.32×10⁵Pa
Internal energy increases ΔU=3990 J
To find
Change in volume ΔV
Solution
First we need to find the work done
So
W=Q-ΔU
W=3220J-3990J
W= -770J
Now for the change in volume at constant pressure
ΔV=(W/P)
ΔV= -5.833×10⁻³
Negative sign indicates that volume decreases

Hello
You expect to see:
1) A solar eclipse, when the earth is between the sun and the moon: the shadow of the earth is projected on the moon surface, and the sun will appear dark
2) An "earth eclipse", when the moon is between the sun and the earth: the shadow of the moon is projected on the earth surface, therefore the earth will appear dark.
A eclipse of the sun can only occur at a new moon when the moon passes between earth and sun. If the moons shadow happens to fall upon earths surface at a time, you'll see some portion of the suns disk covered or aka eclipsed by the moon.. I hope that helps
