How to use Kepler's three laws to deduce the law of universal gravitation

How to use Kepler's three laws to deduce the law of universal gravitation

There is a derivation process in the textbook

Why is the thinking process of Newton's discovery of the law of universal gravitation "supposition theoretical deduction experimental test"?

Any science is imaginary, and then revised in practice! Edison, Darwin and so on are!

What is the positional relationship between the bisectors of two adjacent complementary angles______ ．

Because the size relationship of the adjacent complementary angle is that the sum of the two angles is 180 degrees, the angle formed by the bisector of the two angles is 12 × 180 degrees = 90 degrees. Therefore, the position relationship of the bisector of the two adjacent complementary angles is vertical

What is the bisector of two complementary angles?
a. Coincidence
b. They are opposite extension lines
c. Perpendicular to each other
d. Not sure

c. Perpendicular to each other

Is it correct that bisectors of two adjacent complementary angles must be vertical

Right

What is the position relationship of bisectors of a group of adjacent complementary angles (angles complementary and having a common edge)

Vertical

If an angle is 30 less than its complement, what is the degree of the angle

This corner
=（180-30）÷2
=150÷2
=75°

If an angle is 30 degrees smaller than its adjacent complementary angle, find the degree of the angle

（180°-30°）÷2=75°
If I can help you,

If the adjacent complementary angle of an angle is equal to three times the angle, find the angle
Urgent, can there be a process?

Let this angle be a
The sum of this angle and its complement is 180 degrees
The complement of this angle is 3a
So 3A + a = 180
A=45
Arithmetic: this angle is a multiple of one
So the angle is 180 / (1 + 3) = 45 degrees

If the ratio of the remainder of an angle to the complement of the angle is 2:7, find the adjacent complement of the angle

Let the angle be α, then the remainder of the angle is 90 ° - α, and the complement of the angle is 180 ° - α. According to the title, the ratio of the two angles is: (90 ° - α): (180 ° - α) = 2:7. So 360 ° - 2 α = 630 ° - 7 α, 5 α = 270 °, so α = 54 °. Thus, the adjacent complement of the angle is 180 ° - 54 ° = 126 °
