Answer:
From certain assumptions that the walking speed is 2 m/s, and the stop time is 0.1 s the acceleration would be -20 m/s
Explanation:
Using the average acceleration formula:
where 
and 
are the changes in the speed and time respectively.
We have by assuming that the walking speed is 2 m/s and the stop time is 0.1s which is equal to the change in time during the stopping.
, where 
are the initial speed and final speed respectively, and 
Plugging the previous in the average acceleration formula we get
where the minus sign indicates an acceleration in the opposite direction of the motion (or in other word opposite to the speed's direction).
1) The minute travels the circumference of a 4 inches circle is 60 minutes:
Circumference = 2πr = 2π(2in) = 4π in
Time = 60 minutes
2) Constant angular velocity => (4π / 60) = (x / 20) => x = 4π / 3 inches
x = 4.19 inches
Answer: 4.19 inches
Apart from cutaneous respiration<span> present in all </span>species<span>, most lissamphibians are born in an aquatic larval stage with gills. After metamorphosis, they develop lungs to breathe on land. The larvae of urodeles and apods present external, filamentous and highly branched gills which allow them to breathe underwater.

After fertilization in the fallopian tube, It will take 6-12 days for the zygote to travel before arriving at the uterus.
<h3>What is a zygote?</h3>
A zygote is, generally speaking, a cell created by the fusion of two gametes; the growing person is created from such a cell.
It takes the zygote around 6–12 days following fertilization in the fallopian tube for the fertilized egg to travel to the uterus and attach to the uterus, a process known as implantation.
Hence It will take 6-12 days for the zygote to travel before arriving at the uterus.

<span>The latitude 20 degrees north and longitude 65 degrees west is in the Atlantic Ocean, north of Puerto. The north coast region of Puerto Rico named "Porta Atlantico" faces the dark blue Atlantic Ocean. On the off chance that you long for unwinding on a tranquil shoreline, losing all sense of direction in the magnificence of waves smashing, and being calmed by their song, you might need to remain on the north drift, lease an auto and investigate.</span>
