A wire with a mass of 1.19 g and a length of 1.22 m is placed under tension on a sounding board. The distance between the two frets of the sounding board is 1.15 m. The string is plucked and the sound pulse is sent through a frequency analyzer. Two of the harmonics are 400 Hz and 480 Hz. Assuming these two harmonics are consecutive (no other harmonic frequencies between them), what is the tension in the wire

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
