Use the small angle approximation to calculate the angular size of Venus, in arcseconds at both its closest approach to Earth and its most distant.
Venus diameter = 1.2x104 km
Closest approach: Distance = 4.47x10 km
Furthest approach: Distance = 1.94x108 km
How did Galileo's observations of the changing angular size of Venus help prove the heliocentric
model of the Solar System?
Note 1 radian = 206265 arcseconds

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

the height of the surface increases from the center out to the sides of the road

it is c!

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
