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:
Explanation:
Radius of the ball is
Initial speed of the ball is
Initial angular speed of the ball is
Coefficient of kinetic friction between the ball and the lane
is
Due to the presence of frictional force, ball moves with
decreasing velocity.
(a)
velocity in terms of is
(b)
Ball's linear acceleration is given by
(c)
During sliding, ball's angular acceleration is calculated as
(d)
The time for which the ball slides is calculated from the
equation of motion is
(e)
Distance traveled by the ball is
(for)
The speed of the ball when smooth rolling begins is
Answer:
B) is downward
Explanation:
The acceleration is always downward, because it is the gravitational acceleration.
When the ball is going up the acceleration is opposing the movement, and when the ball is going down the velocity has the same direction as the acceleration
The coloring and water were more ordered before the stirring. The color was defined to on drop but now it has spread throughout the water.
This increase in disorder is dictated by the second law of thermodynamics, which states that the entropy, or state of disorder, of a system increases.
