The potential energy of a swing is greatest at the top of the swing. (Point A).
Answer:
Orbital Time Period is 24 years
Explanation:
This can be explained by the definition of time period.
Time period can be defined as the time taken by an object to complete one cycle, here, time taken to complete one revolution.
Also, we know that an extra solar planet which is also called as an exo planet is that planet which is outside our solar system and orbits any star other than our sun. The system in consideration is extra solar system with a single planet.
Therefore, the time taken by the parent star to move about its mass center is the orbital time period that is 24 years.
What we have so far:
*Distance you walked the dog = 0.75 miles
*Conversion: 1 mile is approximately 1.61 kilometers
What we are trying to find:
*Distance you walked the dog in kilometers.
To solve this problem we must:
*We must employ conversion first.
Step 1) 0.75miles x 1.61km/1miles <--- Multiplication will be employed.
Step 2) 0.75 x 1.61/1 (km)<--- notice that we deleted the unit "miles". We did that to make sure that the result will be in kilometers (km).
Step 3) 0.75 x 1.61(km) <--- Since we are already done with the conversion process, we now have to multiply the distance and the conversion factor.
Step 4) 1.2075km <--- Raw result.
Step 5) Rounding it up to two decimal places: 1.21km
Therefore, the correct answer is: D. 1.21km
