We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at  each successive hill because of  the force of gravity which converts potential  energy into  kinetic energy.

<h3>What are potential and kinetic energy?</h3>
  • Potential energy is referred to as <em><u>positional energy</u></em>.
  • This means that the object in question gains energy based on its position relative to others.
  • Kinetic energy is the energy of movement.
  • Gravity causes the roller coaster to fall, losing potential energy.
  • This causes it to gain all of the potential energy as kinetic energy.
  • Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

[Co(CN)₆]³⁻ → Yellow
[Co(NH₃)₆]³⁺ → Orange

Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.

- Ligands strength order:     CN⁻ > NH₃ > F⁻ 

- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻

- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.

- So CN complex will absorb at lower wavelength (yellow color)

jeyben [28]

Answer: through energy carriers, ATP and NADPH

Explanation:in the light dependent stage,energy from a light photon is used to create ATP through ADP and an inorganic phosphate.

It does this by the transfer of energetic electron from one electron carrier to another.NADPH is also formed.

In the light independent reaction,ATP and NADP are used to reduce carbon dioxide to 3-phosphoglycerate

A 1.50-kilogram ball is attached to the end of a 0.520-meter string and swung in a circle. The velocity of the ball is 9.78 m/s.
Sedaia [141]

Answer:

F centripetal force (tension) = 275.9  N

Explanation:

Given data:

Mass = 1.50 kg

Radius = 0.520 m

Velocity of ball = 9.78 m/s

Tension = ?

Solution:

F centripetal force (tension) =  m.v² / R

F centripetal force (tension) = 1.50 kg . (9.78 m/s)² / 0.520 m

F centripetal force (tension) = 1.50 kg . 95.65 m²/s² / 0.520 m

F centripetal force (tension) = 143.5 kg. m²/s² / 0.520 m

F centripetal force (tension) = 275.9  N
