The scientific method is the method used for scientific discovery.

<h3>What is the scientific method?</h3>

The scientific method is the process or procedure which scientists follow in their discovery and explanation of natural phenomena.

The scientific method is as follows:

  • Observations/Questions
  • Hypothesis
  • Experiments
  • Results
  • Conclusions

Using the scientific method to determine if water is needed by plants to grow

Question: Is water needed for growth in plants?

Hypothesis: Plants need water

Independent variable: sunlight

Dependent variable: rate of evolution oxygen

Constant variable: sunlight and soil

Materials: Cupboard, soil, potted plant, water,

Procedure: One potted  potted plant is watered, while the other is not watered. The length of the plant is measured after 10 days

Observation: The watered plant survived and grew while that which was not watered did not grow but died.

Conclusion: water is needed for growth in plants.

In conclusion, the scientific method can be used to determine if plants need water for growth.

Explain how dalton's theory of the atom and the conservation of mass are related
Scorpion4ik [409]

Answer:

Dalton's atomic theory states that atoms may be mixed in certain rations to produce compounds, while the law of conservation of mass states that the mass of reactants equals the mass of products. They are related because in the production of compounds, Dalton made it clear that mass can neither be destroyed or created, which supports the conservation of mass law.

A complex absorbs photons with an energy of 4.10×10^−19 J. What is the wavelength of these photons? If this is the only place in
MaRussiya [10]

Answer:

483 nm corresponds to blue light hence the complex will appear orange.

Explanation:

Using the formula;

E= hc/λ

Where;

E = energy of the photon

h = Plank's constant (6.6*10^-34Js)

c = Speed of light (3*10^8 ms-1)

λ = wavelength

λ = hc/E

λ = 6.6*10^-34 * 3*10^8/4.10×10^−19

λ = 4.83 * 10^-7 or 483 nm

483 nm corresponds to blue light

Using the colour wheel approach, if a complex absorbs blue light, then it will appear orange.
