Acceleration in m/s^2 = 2/10 = 0.2 m/s^2
Answer: D. it has been demonstrated to be without exception under certain stated conditions.
Explanation:
A <u>Law</u> is an affirmation (something established) based on repeated long-term observation of a phenomenon that has been studied and verified.
That is: A law is present in all known theories and therefore is considered universal. In addition, a law can not be refuted, nor changed, because its precepts have been proven through various studies.
<u>Unlike theory</u>, which is the set of rules and principles that describe and explain a particular phenomenon and <u>is subject to changes as new evidence emerges that gives meaning to it. </u>
Then, based on what is explained above, the law of universal gravitation is a statement that exists because it was rigorously tested and verified, therefore it can not be refuted.
I believe all the insulators would be glass, wood, plastic, and yarn.
But I’m not entirely sure if mechanical pencil lead is an insulator or conductor.
Hope this helps.
Answer:
a) 0.477 W/m²
b) 13.407 N/C
c) 18.96 N/C
Explanation:
P = Power = 150 W
r = Distance = 5 m
ε₀ = Permittivity of space = 8.854×10⁻¹² F/m
a) Average intensity
∴ Average intensity is 0.477 W/m²
b) Rms value
∴ Rms value of the electric field is 13.407 N/C
c) Peak value
∴ Peak value of the electric field is 18.96 N/C
