The higher the frequency, the higher or sharper (the musical term if you prefer such things) the pitch is.
Answer
Force between two charged bodies q₁ and q₂ is given by the formula below.
F = Kq₁q₂/r²
Where k = constant
r = distance between them
F = (9.0 E9 × 1.0 E-6 × 1.0 E-6)/0.30²
= 9.0E-3/0.30²
= 9.0E-3/0.09
= 0.1 N
C is the correct answer.
all substances found on the periodic table are elements by definition. anything that is created using elements, such as methane, carbon dioxide, or water, are all compounds.
The answer to this question is a the estimate the speed of light
Answer:
D) Dalton's theory had repeated observations which were supported by extensive evidence.
Explanation:
Dalton had a basis for this prediction and theory. He worked extensive on gases before stepping forward with the Dalton's atomic theory.
His scientific conjecture was highly corroborated with a wide array of experimental evidence and many infallible proofs.
- Science is a logical way of reasoning that follow methodological approaches.
- It deals with empirical experimental proofs that must have been gathered and the veracity ascertained.
- Dalton during his time presented the scientific community with a pool of observations balanced with experimental evidences he accumulated with time.
