Answer:
The current is 0.951 A
Solution:
As per the question:
Capacitance of the capacitor, C = 
Resistance of the circuit, R = 14.0
Voltage of the battery, V = 10.0 V
Now, when the charge become one-fourth of its initial value, the amount of current flowing is given by:
(1)
where
q' = 








Now,
The current is given by:
(2)
Also, 
Now, using the value of I = 0.714 A

Kinetic energy is the energy of a moving object.
Kinetic energy can be calculated using the following equation;
K.E =

where - m - mass of object
v - speed of object
substituting the values in the equation
K.E = 1/2 x 21 kg x (1 m/s)²
K.E = 10.5 J
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.
