Which contributions did johannes kepler make? select three options. he revived aristotle’s model of the solar system. he solved ptolemy’s model by proving elliptical orbits. he proved galileo’s calculations were incorrect. he determined that planets move faster when closer to the sun. he discovered laws of planetary motion.
Answer:
2
4
5
Explanation:
Kepler's laws of planetary motion are rules that describe how the planets move within the solar system in astronomy and classical physics.
What is Planetary motion?The astronomer Tycho Brahe made observations in the 16th century, and these observations were analyzed by the German astronomer Johannes Kepler, who announced his first two laws in 1609 and a third rule nearly ten years later, in 1618.
Kepler never assigned a number to these rules or made a clear distinction between them and his other discoveries.
According to Newton, the motion of bodies subject to central gravitational force need not always follow the elliptical orbits specified by Kepler's first law but can also follow paths defined by other, open conic curves.
Therefore, Kepler's laws of planetary motion are rules that describe how the planets move within the solar system in astronomy and classical physics.

What are the minimum number of bits an address bus must have in a byte addressable memory system containing only 4 KiB of memory
The minimum number of bits the address bus must have in the byte addressable memory system is 12
How to determine the minimum number of bits?The memory size is given as;
Size = 4 KiB
Convert to bytes
Size = 4 * 2^10 bytes
Express 4 as 2^2
Size = 2^2 * 2^10 bytes
Multiply
Size = 2^12 bytes
The minimum number of bits is then calculated as;
2^n = Size
This gives
2^n = 2^12
Cancel out the base (2)
n = 12
Hence, the minimum number of bits is 12
