Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)
Answer:
27 m/s
will be the new velocity
Explanation:
if acceleration is 3 then it must be 3 m/s^2
12kN is equal to 12000 N
and the perpendicular component will be
[email protected] mg = 12000 N
cos10°= 0.984
thus it will be 12000*0.984 = 11808N
the frictional force will be
[email protected]sin10° = 0.1736
and hence it will be = 2083N
Hence, 0.60+2.25eV is the solution to this problem
A person usually breathes an average of 13 pints of air every minute.
Lungs aren't the same size. To accommodate the heart, the right lung is larger than the left lung — for humans, that is.
