Answer:
The answer is 1.87nm/s.
Explanation:
The water loss must be replaced by of sap. 110g of sap corresponds to a volume of
thus rate of sap replacement is
The volume of sap in the vessel of length is
,
where is the cross sectional area of the vessel.
For 2000 such vessels, the volume is
taking the derivative of both sides we get:
on the left-hand-side is the velocity of the sap, and on right-hand-side ; therefore,
and since the cross-sectional area is
;
therefore,
solving for we get:
which is the upward speed of the sap in each vessel.
Can i have more information?
Answer:
Explanation:
Required
The units of A and B
From the question, we understand that:
This implies that each of and will have the same unit as
So, we have:
The unit of t is (s); So, the expression becomes
Divide both sides by
Answer:
0.5m/s^2
Explanation:
We can use the formula [ F = ma ] but solve for "a" since that is what we are looking for.
F = ma
F/m = a
We know the net force and mass so substitute those values and simplify.
500/1000 = 0.5m/s^2
Best of Luck!
