Kepler's third law, referred to as the law of harmonies, is used to calculate the orbital period and radius of a planet based on the dimensions and periods of another planet. This relationship is directly proportional to the square of the period and inversely proportional to the cube of the distance. Therefore, when the distance is tripled ((3D)^3), the period should increase to the square root of 27 times 5.20 times the initial period,
Answer:
D. All are equal
Explanation:
The only force acting on the objects is gravity, which is consistent across all items
Answer:
The runner's deceleration is -23.33 
Given:
Initial speed = 3.5 
Final speed = 0
Time taken = 0.15 s
To determine:
Deceleration of the runner =?
Used Formula:
Using the first equation of motion,
v = u + at
Where, v = final speed
u = initial speed
a = deceleration
t = duration
Solution:
<pusing the="" first="" equation="" of="" motion="">
v = u + at
Where, v = final speed
u = initial speed
a = deceleration
t = duration
0 = 3.5 + a (0.15)
-3.5 = 0.15 (a)
a = 
a = -23.33
The negative sign indicates that this represents deceleration.
Hence, the deceleration of the runner is -23.33

Response: Numerous elements can be found, all situated within the same vertical column as bromine.
Explanation:
Elements are organized by their atomic numbers on the periodic table. Those in the same vertical column (known as groups) exhibit the same valence electron configurations, resulting in similar chemical characteristics. Consequently, there are numerous elements sharing analogous chemical properties grouped with Bromine.
