360.67 is the speed of waves on a violin string of mass 707 mg and length of 21.4 cm if the fundamental frequency is 867 Hz.
Mass per unit length of string н = mass/length
= 505×10⁻⁶ kg/ 0.204 m
= 2.47×10-³ kg/m

Fundamental frequency ∫о=884 Hz
a. Speed of waves v = 2L∫о
= 2×0.204 m x 884 Hz
=360.67 m/s.
For example, if the fundamental frequency is 50 Hz (also called the first harmonic), the second harmonic is 100 Hz (50 * 2 = 100 Hz), and the third harmonic is 150 Hz (50 * 3 = 150 Hz ). Such.
The fundamental frequency is the lowest frequency of the resonant system. This is an important concept in many aspects of musical instruments and engineering. For example, all harmonics of a particular wave are based on the fundamental frequency.

Answer:
(a) You can tell that have the same strength because they have attracted the same amount of paper clips.
(b) Iron is used in electromagnets because steel retained magnetic properties after the power was turned off, but in the iron, the paper clips dropped off right away.
Answer:
I = 5000 A
Explanation:
We will use Ampere's Law to calculate the current:
where,
B = Magnetic Field Strength = 0.1 mT = 1 x 10⁻⁴ T
μ = Permeability of Free Space = 4π x 10⁻⁷ N/A²
I = Current = ?
r = radius = 10 m
Therefore,
<u>I = 5000 A</u>
Answer:
Explanation:
1 foot = 12 inches
Sammy is 5 feet tall.
5 feet = ? inches
Multiply the feet value by 12 to find in inches.
5 × 12
= 60
Add 5.3 inches to 60 inches.
60 + 5.3
= 65.3
The fastest in speed of sound is steel. The slowest in speed of sound is oxygen. Hope this helped! I don't really know how to answer this but by looking at the table it looks like this can be one of the conclusions.
