It will be sediment, that's the only thing can be in a rock and it's a living thing. Sediment is part of a rock so that's your answer this is a 7th grade question not that hard I'm in the 5th grade no officence but enjoy your answer
Answer:
i believe it is dna
Explanation:
if i remember correctly if the dna tells the cell what to do and how to do it
Answer:
a) 
b) 
Explanation:
Given:
- mass of the body,

- mass of the tyre,

- length of hanging of tyre,

- distance run by the body,

- acceleration of the body,

(a)
Using the equation of motion :
..............................(1)
where:
v=final velocity of the body
u=initial velocity of the body
here, since the body starts from rest state:

putting the values in eq. (1)


Now, the momentum of the body just before the jump onto the tyre will be:



Now using the conservation on momentum, the momentum just before climbing on the tyre will be equal to the momentum just after climbing on it.



(b)
Now, from the case of a swinging pendulum we know that the kinetic energy which is maximum at the vertical position of the pendulum gets completely converted into the potential energy at the maximum height.
So,



above the normal hanging position.
Displacement only contain the length of movement and the direction of that movement
So you can pretty much disregard the speed.
30 to the west than 40 to the east
The displacement will be 10 km to the east
hope this helps
D. Assuming that it doesn’t accelerate and then decelerate between seconds.
