Some scientist believe that the ozone layers of the earth had been weakening and the waters or current changes direct ever 5-7 month.
We can find the force by using the following formula;
N = ma + mg
Fa = ma = 76 x 1.2 = 91.2
Fg = mg = 76 x 9.8 = 744.8
N = 91.2 + 744.8 = 836
So, the force is 836 N.
Answer:
12m/s
Explanation:
v^2=u^2+2as
v=?
u=0 (the dish was stationary before it fell)
a=9.81 m/s^2 (acceleration due to gravity/freefall)
s=1.5m (the drop height)
So: v^2=0+2.9.81.1.5 = 144.35415
and therefore v=sqrt 144.35415
12x12=144 so I'd say v=12m/s
I think the answer is Fe3+
