To determine a planet's mass, astronomers typically measure the minuscule movement of the star caused by the gravitational tug of an orbiting planet. For planets the massof Earth detecting such a tiny tug is extraordinarily challenging with current technology

This is the answer if you are on edginuity,
Answer:
K= 25.16%
Mn= 34.59%
O= 40.25%
Explanation:
Find the total mass of the compound. You can do this by multiplying by the molar mass.
add them:
40+55+64=159g
Now convert each element individually to grams using molar mass
Divide by the mass of the compound and multiply by 100
Answer:
1, 2, 0, 1
Explanation:
The bonds between atoms can be explained in terms of hybrid orbitals. The kind of hybrid orbital depends on the kind and number of atomic orbitals that hybridize.
In order to produce sp² hybrid orbitals, 1 s atomic orbital, 2 p atomic orbitals, and 0 d atomic orbitals must be mixed/hybridized.
There are 3 p orbitals in each p sublevel.
After the hybridization, there is 1 unhybridized p orbital around the central atom.
