Answer:
Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/
(newtons per meter squared).
Answer:
Ultraviolet light has shorter wavelengths than infrared light. The frequency of ultraviolet light is greater than that of infrared light. Ultraviolet light is higher in energy than infrared light.
Answer:
No.
Explanation:
Hot spots don't appear at the barriers of tectonic plates, instead, they originate at hot centres known as mantle plumes. Mantle plumes exist below the tectonic plates and may develop a string of volcanoes on the Earths surface.

Answer:
717 Hz
Explanation:
<u>solution:</u>
The wave with three antinodes has m = 3. Thus, f_3 = 3f_1 and so the fundamental frequency of the string is
f_1 =f_3/3
=430 Hz/3
=143 Hz
Thus, the frequency of the fifth harmonic is
f_5 = 5*f_1
= 5*143 Hz
= 717 Hz
