Answer:

<h3>How do you determine if a solution is isotonic hypertonic or hypotonic? </h3>

In comparing two solutions of unequal solute concentration, the solution with

the higher solute concentration is hypertonic, and the solution with the lower

solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.

A ball is thrown into the air at a velocity of 44 feet per second. Its height in feet, h after t seconds is represented by the e
Lady_Fox [76]

Answer:

0.447 sec

Explanation:

velocity = distance/ time

distance 'h' is a function of time 't' given by

h = 12t^{2} + 44t + 16

⇒ differentiating equation

⇒ velocity = \frac{dh}{dt} = 24t + 44

⇒ acceleration = \frac{d^{2}h }{dt^{2} } = 24 \frac{ft}{sec^{2} }

deceleration due to gravity = -9.8 m/sec^{2} =  - 9.8 x 3.281 = - 32.154 ft/ sec^{2}

Net deceleration = 24 - 32.154 = - 8.15 ft/ sec^{2}

at maximum height v = 0

v^{2} = u^{2} + 2ah

⇒  0 = 44^{2} + 2 (-8.15)h

⇒ h = 118.72 ft⇒

118.72 = 12t^{2} + 44t + 16

⇒ 12t^{2} +44t - 102.72 = 0

⇒  t = -44 ± \sqrt{44^{2} - 4(12)(102.72) }     / (2 x 12)

t = 0.447 sec
