If a violin string vibrates at 430 hz as its fundamental frequency,then the frequencies of the harmonics are 880, 1320, 1760
The frequency in physics is the number of waves passing a fixed location in a unit of time. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time.
How frequently something occurs is what is meant by the word frequency. A person blinking their eyelids 47 times in a minute is an example of frequency. the quality or state of happening frequently.
Integer (whole-number) multiples of the fundamental frequency are used to define harmonics, which are voltages or currents that function at certain frequencies. This means that for a waveform with a fundamental frequency of 50 Hz, the second harmonic frequency would be 100 Hz (2 x 50 Hz), the third harmonic would be 150 Hz (3 x 50 Hz), etc.

Answer:
1467 atoms
Explanation:
5730 yrs = carbon 14 half life
10 740 / 5730 = 1.87 half lives
400 = C (1/2)^1.87
C = original = ~1467 atoms
Answer:
1.8 m/s
Explanation:
= Mass of Max = 15 kg
= Mass of Maya = 12 kg
= Initial velocity of Max = 8.2 m/s
= Initial velocity of Maya = -4.6 m/s
= Final velocity of Max
= Final velocity of Maya = 3.4 m/s
In this system the linear momentum is conserved
The velocity of Max after their collision is 1.8 m/s
Answer;
the colors of light that plants require for photosynthesis
Explanation;
The color of light used for photosynthesis depends on the pigment in the plant. For example, green plants with chlorophylls and carotenoids have a maximum activity with violet-blue and red light.
White light contains various colors, including red, orange, yellow, green, blue, indigo and violet. When plants harvest light for photosynthesis, they only absorb a few colors and reflect the rest. Plants appear green because chlorophyll absorbs other colors and reflects green.
Answer:
Explanation:
The Law of Momentum Conservation for us has the equation
and filling in:
and
2.5 = 1.0 + .50v and
1.5 = .50v so
v = 3 m/s
