Answer:
Its position after 4 seconds is 62 meters.
Explanation:
It is given that,
The acceleration of the particle is given by equation :

Also, 



At t = 0,
. So, c = 3

Also,
, s is the position



At t = 0,
. So, c' = 10

At t = 4 s

s = 62 m
So, at t = 4 seconds the position of the particle is 62 meters. Hence, this is the required solution.
D. There is a known constant concentration of C14 in Nature. As we consume living things to survive our bodies (made of carbon) stop replenishing our body's carbon (we stop eating) and start to decay. Since we know the 1/2 life of C14 and the ratio of C14 to normal C12 we can determine fairly accurately how long ago a thing stopped consuming carbon (e.g. when it died)
Answer:
Needs, Wants
Explanation:
Needs are necessary, wants are not
I have that problem, the only thing that helps me is to look at someone I know, like my parents or my sister or grandma etc. and don't think about what other people might think about you.
So good luck.
I hope this helps you.
