You can use mostly anything as long as it is circular. Depending on how big it is, you could use sturdy paper plates and use a stick/rod and tape to hold it together, or you could use bottle caps if the car you are trying to make is really small.
Relative dating is used to arrange geological events….
Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event….
Relative Dating uses the half life of isotopes to get the exact age of a rock or mineral.
Answer:
8
Explanation:
Groups go down, periods go across :)
answer
no
Explanation:
I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
Answer:
There is an interval of 24.28s in which the rocket is above the ground.
Explanation:
From Kinematics, the position 
as a function of time when the engine still works will be:
At what time the altitud will be ?
⇒ 
Using the quadratic formula: 
.
How much time does it take for the rocket to touch the ground? No the function of position is:
Where our new initial position is 
, the velocity when the engine breaks is 
and the only acceleration comes from gravity (which points down).
Now, when the rocket tounches the ground:
Again, using the quadratic ecuation:
Now, the total time from the moment it takes off and the moment it tounches the ground will be:
.
