What Is Common Diference Of 160,80,40,20?

What is common diference of 160,80,40,20?

 

Answer:

The given sequence is geometric so there is a common ratio of 1/2, not a common difference.

Step-by-step explanation:

160,80,40,20  is a geometric sequence.

Therefore, it has no common difference but a common ratio.

A common difference is for arithmetic sequence.

To find the common ratio:

a₂/a₁ = a₃/a₂

80/160 = 40/80

1/2 = 1/2

Therefore the common ratio is 1/2.

When The Cardboard Is At Rest,How Do The Magnitudes And Directions Of The Pair Of Forces Acting On It Compare

when the cardboard is at rest,how do the magnitudes and directions of the pair of forces acting on it compare   Answer: When an object (cardboard) is at rest, only 2 forces are acting on it: Gravitational Force and Support Force . The Gravitational Force pulls the object down, while its reaction force ( Support Force ) pushes it up. Example: A book is at rest on a table. Gravity is pulling the book down to the ground, but the table that its on is supporting it (pushing it up).
