Answer:
The correct option is;
c. The scientist can make and record observations
Explanation:
Empirical evidence are evidences obtained by direct observation, sensual perception or direct measurement. It is the processed and useful data gathered and stored in a material form or documented to provide record of the measurement.
With the aid of empirical evidence, it is possible for researchers to find answers to question regarding topics that can vastly impact every day life.
With empirical evidence, it is possible to determine the effects of treatment in a study such as the invention of working car safety devices such as seat belts and airbags.
Answer: Inversely , Directly
Explanation:
The energy of a photon is inversely proportional to its wavelength and directly proportional to its frequency.
As can be seen from this equation;
E = hv = h c / ∧
Where E = Energy of a photon
v = Frequency
h = Planck Constant
c = speed of light
∧ = Wave length
I don’t see what you need help with but thanks:)
Answer:
H2O and CO
Explanation:
they both form covalent bonds because none both of the elements are non-metal. Mgo and NaF both have metals in them so they would form ionic bonds.
Covalent bonds, two non-metal
Ionic bonds, a metal and a non-metal
Answer:
We have the final answer as
<h2>9.85 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of substance = 223.5 g
volume = final volume of water - initial volume of water
volume = 68.3 - 45.6 = 22.7
volume = 22.7 mL
It's density is
We have the final answer as
<h3>9.85 g/mL</h3>
Hope this helps you
