Which formula can be used to find tangential speed of an orbiting object?

A)

Explanation:

As we know that the speed of the object is defined as the the ratio of total distance and total time taken

now as we know that here the distance along the path of the orbiting object is total length of the circle

so it is given as

also we know that

time period to complete the orbit is given as

now the speed is given as

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

from

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
