Answer: it should be 136 square centimetres
Explanation:
Actually the position function with respect to time under constant acceleration is:
a=g
v=⌠g dt
v=gt+vi
s=⌠v
s=gt^2/2+vit+si
So if vi and si are zero then you just have:
s=gt^2/2
Notice that it is not gt^2 but (g/2) t^2
So the first term in any quadratic is half of the acceleration times time squared because of how the integration works out...
Anyway....
sf=(a/2)t^2+vit+si
(sf-si)-vit=a(t^2)/2
2(sf-si)-2vit=at^2
a=(2(sf-si)-2vit)/t^2 and if si and vi equal zero
a=(2s)/t^2
Answer:
50
Step-by-step explanation:
it is given that there is one variable with 1000 records
we have to find the records which is expected would be removed
it is given that one variable is missing with 5% that 0.05
we can find missing records by multiplying total number of records and the missing value with one variable
so the expected record removed will be =0.05×1000=50
=
