<h3 /><h3>What is Kepler's third law of motion?</h3>
Kepler's third law of motion states that the the square of the orbital period of
a planet is proportional to the cube of the semi-major axis of its orbit. He
also inferred that the greater the distance, the slower the orbital velocity.
This thereby makes option D the most appropriate option as it contains the
orbital velocity and distance to sun variables.

I found the Hydrolic system, im not sire if its helpful or not. I could only find that one, sorry if it doesn't help but I hope it does ^-^
The theodolite is a precision measuring device used to measure horizontal and vertical angles. It works with a combination of: (1) optical plummets, which is used to ensure that it is placed exactly vertical above; (2) internal spirit, which ensures that it is levelled to the horizon; and (3) graduated circles, one vertical and one horizontal, which is used to measure actual angles. The mounted telescope can swivel horizontally and vertically. If this is adjusted correctly, accurate measurements can be obtained.
Answer:
The pressure at the top of the step is 129.303 kilopascals.
Explanation:
From Hydrostatics we find that the pressure difference between extremes of the water column is defined by the following formula, which is a particular case of the Bernoulli's Principle (
):
(1)
, 
- Total pressures at the bottom and at the top, measured in pascals.
- Density of the water, measured in kilograms per cubic meter.
- Height difference of the step, measured in meters.
If we know that 
, 
, 
and 
, then the pressure at the top of the step is:
The pressure at the top of the step is 129.303 kilopascals.
Whats the question exactly?
