)a steel guitar string with a diameter of 1.00 mm is stretched between supports 80.0 cm apart. the temperature is 0.0°c. (a) find the mass per unit length of this string. (use the value 7.86 x103 for the density (b) the fundamental frequency of transverse oscillations of the string is 200 hz. what is the tension in the string? (c) if the temperature is raised to 30.0°c, find the resulting values of the tension and the fundamental frequency. assume that both the young’s modulus and the average coefficient of expansion have constant values between 0.0°c and 30.0°c.

a. Mass per unit length =0.0245kg/m

b. Tension =2.45x10^-8N

C. Tension = 2.45 x10^-8N

Fundamental frequency =200Hz

Explanation:

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
