Answer: A. The total displacement divided by the time and C. The slope of the ant's displacement vs. time graph.
Explanation:
Hi! The question seems incomplete, but I found the options on the internt:
A. The total displacement divided by the time.
B. The slope of the ant's acceleration vs. time graph.
C. The slope of the ant's displacement vs. time graph.
D. The average acceleration divided by the time.
Now, since we know the ant is travelling at a constant speed, its average velocity will be expressed by the following equation:
Where:
is the ant's total displacement
is the time it took to the ant to travel to the kitchen
Hence one of the correct options is: A. The total displacement divided by the time
On the other hand, this can be expressed by a displacement vs. time graph graph, where the slope of that line leads to the equation written above. So, the other correct option is: C. The slope of the ant's displacement vs. time graph.
To solve this problem it is necessary to apply the concepts related to hydrostatic pressure or pressure due to a fluid.
Mathematically this pressure is given under the formula
Where,
= Density
h = Height
g = Gravitational acceleration
Rearranging in terms of g
our values are given as
Replacing we have
Therefore the gravitational acceleration on the planet's surface is (Almost the gravity of the Earth)
