Answer:
C. Both observation 1 and observation 2.
Explanation:
The heliocentric model states that the Earth and planets revolve around the Sun at the center of the Solar System.
Observation 1 was answered by Nicolas Copernicus, father of the heliocentrism, in 1543. The reverse effect is an illusion created because the Earth revolves faster around the Sun than Mars.
And observation 2 also is explained by the model because the rotation of the earth made that the Stars be closer to it at different times of the year.
I hope this answer helps you.

Gay-Lussacs law states that pressure of a gas is directly proportional to temperature when the volume is kept constant
P / T = k
where P - pressure , T - temperature in kelvin and k - constant
where parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation
T1 - 25 °C + 273 = 298 K
substituting the values in the equation
T2 = 388 K
temperature in celcius - 388 K - 273 = 115 °C
answer is C. 115 °C
The density of a rectangle : ρ = 0.372 g/cm³
<h3>Further explanation</h3>
Given
The volume of rectangle : 395 cm³
Mass : 147 g
Required
The density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 147 g : 395 cm³
ρ = 0.372 g/cm³
