Answer:
0.62
Explanation:
A = Amplitude
f = Frequency = 1.85 Hz
= Coefficient of static
g = Acceleration due to gravity = 9.81 m/s²
Angular frequency
Maximum acceleration
Coefficient of static friction between penny and tabletop is 0.62
Answer:
hydrophilic
Explanation:
hydrophobic means it hates water so a hydrophobic material would separate from the water and just sit there (an example of this is oil)
Answer:
Based on the passage, the article's claim is not true. Therefore, the answer is:
No, because radio waves have energies that are too low to fall in the ionizing range.
Explanation:
Radio waves are generally known as forms of non-ionizing radiation. This means that they do not have enough energy, unlike microwaves, to separate electrons from atoms or molecules, thereby ionizing them. They cannot cause electron displacement, as claimed in the article. Therefore, they cannot break chemical bonds, which can cause chemical reactions or DNA damage. As non-ionizing radiation, radio waves occur at lower frequencies in the electromagnetic spectrum.
