T is the time for a whole round.
centripetal acceleration = V^2/R,
20 = 40^2 / R, find R = 40^2/20 = 40*40/20 = 80 m, right?
Now, one round is L = 2*pi*R = 2*pi*80 = 160*pi
And T = L/v (distance/speed) = 160*pi/40 = 4*pi seconds, or ~ 12.57 s
Answer:
The simplified expression is 3.833 x 10⁷ g
Explanation:
Given expression;
3.88 x 10⁷ g - 4.701 x 10⁵ g
The expression above is simplified as follows;
= (3.88 x 100 x 10⁵ )g - ( 4.701 x 10⁵) g
= (388 x 10⁵ )g - ( 4.701 x 10⁵) g
= (388 - 4.701 ) x (10⁵ )g
= 383.299 x 10⁵ g
In standard form, the simplified expression can be expressed as;
= (3.83299 x 100 x 10⁵) g
= 3.83299 x 10⁷ g
= 3.833 x 10⁷ g
Therefore, the simplified expression is 3.833 x 10⁷ g
XA = PA/PA^0
XA = 22.98/23.76 = 0.9671
0.9671 : 0.0328
bi = ni/msolvent
0.9672 * 18.015/1 mol = 17.42 g H2O
bi = 0.0328 mol urea/17.42 g H2O * 1000
bi = 1.88 m
hope this helps
I think that is clearly in the name. It will use 850W at 100% load if the cos¿ = 1
Well as the fish swims he pushes the water behind him which in return push him forward
