Answer:
18.1347 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a

Total height the ball falls is 2.4619+14.3 = 16.7619 m

The speed at which the stone reaches the ground is 18.1347 m/s
Molecular structure of the primary cell wall in plants. Up to three strata or layers may be found in plant cell walls: The middle lamella, a layer rich in pectins. This outermost layer forms the interface between adjacent plant cells and glues them together.
Condensation<span> is the change of </span>water<span> from its gaseous form (</span>water vapor) into liquid water<span>. </span>Condensation<span> occurs in the atmosphere when warm air rises, cools and looses its capacity to hold </span>water vapor<span>. As a result, excess </span>water vapor <span>condenses to form cloud droplets.</span>
The magnitude of the electric force between two obejcts with charge

and

is given by Coulomb's law:

where

is the Coulomb's constant
and r is the distance between the two objects.
In our problem, the distance is

, while the magnitudes of the two charges are


(we can neglect the sign of the second charge, since we are interested only in the magnitude of the force).
So, using the formula and the data of the problem, we find
Answer:
function is discontinuous
and
after 3 hours upto day 24 hours fix charge $10
so there are discontinuous at 1st hour, 2nd hours and 3rd hours
Explanation:
given data
charge = $3 for 1st hour
charge = $2 for each succeeding hour
maximum charge = $10 daily
to find out
Is this function continuous
solution
their function is 3 +2x
so function is discontinuous here
and
this is very clear for 1st hour or part of hour it mean charge a fix value in given time
anyone who park fix charge for 60 min up to the 3 hours
after that for day 24 hours fix charge $10
so there are discontinuous at 1st hour, 2nd hours and 3rd hours
