Explanation:
Kepler’s third law states that for all objects orbiting a given body, the cube of the semimajor axis (A) is proportional to the square of the orbital period (P).
For each of our planets orbiting the Sun, the relationship between the orbital period and semimajor axis can be represented by the equation as:

k is constant of proportionality
It is required to solve the above equation for k

The block has the greatest average power provided is bock m.
<h3>What is instantaneous power?</h3>
- This is the product of force and velocity exerted on an object.
Mathematically instantaneous power is calculated as;
P = Fv
where;
- F is the applied force
- v is the velocity
Both blocks (m and 2m) will experience the same force but different velocity.
The smaller block (m) will experience greater velocity.
Thus, the block has the greatest average power provided is bock m.

I can only offer you one which is mushroom. They're fungus' and they can't produce their own food. They get their food from decaying and dead animals and absorb it through their roots.
