Answer:
c. hot material must be rising from the Sun's hotter interior
Explanation:
Granulation is the grainy appearance of the solar photosphere produced by the top of the convection cells in the sun.
The grainy appearance are produced by granules on the photosphere of the sun and granules are caused by convection currents of plasma within the sun's convection zone.
The interior of these granules are brighter (and thus hotter) than the exterior of the granules which are darker.
<u>So, the granulation pattern that astronomers have observed on the surface of the Sun tells us that hot material must be rising from the Sun's hotter interior.</u>
Answer:
The Required pressure for this situation is P= 735000Pa
Explanation:
In Determining the required pressure in this situation we use two equations
First one is
F = mg = (ρhA)g
And Second one is
P = 
= (ρhAg)/A Where P is pressure
We get
P = ρhg
since g = 9.8 m/s and h is given that is 75m and ρ = 
so
P = (9.8 m/s)()(75) we get
P = 735000 Pa
B: Gravity.
The force of gravity will pull the car down the hill. The weight/mass of the car also helps this.
Answer:
2280 V
Explanation:
distance between the plates, d = 4 cm = 0.04 m
Electric field strength, E = 5.7 x 10^4 V/m
The formula for potential difference is given by
V = E x d
V = 5.7 x 10^4 x 0.04
V = 2280 V
thus, the potential difference between the plates is 2280 V.
There are asteroids, which are rocks that fly through the space, and meteors which are pretty much the same. The only difference is their sizes. There are also planets, big and small. The moon, the dwarf planet Pluto, and many more. There are probably thousands of other planets that we haven't quite yet discovered. Soon we will though. There are also billions of stars, such as the sun, and some others we don't have names for that form constellations.
Hope this helped!!
