KE=3070.625 J
Height = 3.686 m
<h3>Further explanation</h3>
mass of bike+rider=85 kg
velocity = 8.5 m/s
Conservation of energy :
(KE+PE)₁ (downhill) = (KE+PE)₂ (up the hill)
PE₁=0⇒h=0
KE₂=0⇒v=0(stop), so equation becomes :
KE₁=PE₂
Water. About 71% of the Earth's surface is covered in water.
Hope this helped!
To neutrilize you meed equal moles of H+ and OH - so they are converted into water. 2.0 M * 0.036= 0.072 moles of NaOH and moles of NaOH = moles of OH- . So 0.072 moles of H+ are needed so 1.5*x=0.072. X= 0.048 Liters of HCl (aq)
