Answer:
The fossil evidence of both an ocean and a forest can be found at different depths in the same location because there might have been a presence of both an ocean and a forest at the same location at different times in the history of Earth.
Explanation:
It is clear from various studies that the Earth has had a diverse geologic history in which events like drastic climate changes, upsurging of oceans, rapid desertification, etc., have taken place many times.
Thus, the possibility of an ocean and forest having shared a single location at different times in the history of Earth cannot be neglected.
You have to use the equation F=ma and solve for m to get m=F/a.
m=mass in kg
F=force (in this case 350N)
a=acceleration (in this case 10m/s²)
when you plug everything in you should find that m=35kg
I hope this helps.
Answer:
two north poles and two south poles
Explanation:
A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.
No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.
