Which type of scientific statement describes a proven fact about how things function in nature? a law a theory an inquiry a hypothesis
The key word is "proven fact". The answer is: a law.
Answer:
B.lenses bounce light from their surface, mirrors do not
The net force on the system:
F = m₂g - m₁gsin(∅)
F = 39.5 x 9.81 - 43 x 9.81 x sin(30)
F = 176.58 N
Now, we use F = ma to find the acceleration on each mass.
F = m₁a₁
a₁ = 176.58 / 43
a₁ = 4.11 m/s²
F = m₂a₂
a₂ = 176.58 / 39.5
a₂ = 4.47 m/s²
The Joule, the BTU, and the calorie are units of energy,
in the form of heat or in any other form.
The Kelvin is a unit of temperature.
Choices A, B, and D are false statements.
I think choice-C is trying to say the right thing, but it
might have gotten copied incorrectly.
Electric fields and electric forces both increase as the distance
decreases, and decrease as the distance increases.
