Assume each tick mark represents 1 cm. calculate the total displacement from 0 if an object moves 3 cm to the left, then 7 cm to the right, and then 6 cm to the left

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.

The final displacement is 2 cm to the RIGHT .

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

ratio is 2 : 9

the answer is three

13.5 : 3
