At point E
- the kinetic energy of the rollercoaster is small compared to the potential energy
- the potential energy is greater than the kinetic energy
- the total energy is a mixture of potential and kinetic energy
<h3>What is the energy of the roller coaster at point E?</h3>
The energy of a roller coaster could either be potential energy, kinetic energy or a combination of both potential and kinetic energy.
Using analogies, the energy of the roller coaster at point E can be compared to a falling fruit from a tree which falls onto a pavement and is the rolling towards the floor. Point E can be compared to the midpoint of the fall of the fruit.
At point E
- the kinetic energy of the rollercoaster is small compared to the potential energy
- the potential energy is greater than the kinetic energy
- the total energy is a mixture of potential and kinetic energy
In conclusion, the energy of the rollercoaster at E is both Kinetic and potential energy,

Answer:
R = 9.85 ohm , r = 0.85 ohm
Explanation:
Let the two resistances by r and R. 
when they are connected in series:
V = 12 V 
i = 1.12 A
The equivalent resistance when they are connected in series is 
Rs = r + R 
So, By using Ohm's law
V = i Rs
Rs = V / i = 12 / 1.12 = 10.7 ohm 
R + r = 10.7 ohm    .... (1)
When they are connected in parallel:
V = 12 V 
i = 9.39 A
The equivalent resistance when they are connected in parallel

So, By using Ohm's law
V = i Rp
Rp = V / i = 12 / 9.39 = 1.28 ohm 
 .... (2)
    .... (2) 
by substituting the value of R + r from equation (1) in equation (2), we get 
r R = 8.36 ..... (3)

 ..... (4)
 ..... (4)
By solvng equation (1) and (4), we get 
R = 9.85 ohm , r = 0.85 ohm
 
        
             
        
        
        
In several of the questions you've posted during the past day, we've already said that a wave with larger amplitude carries more energy.  That idea is easy to apply to this question.
