Two Strings Are Made of the Same Material

Question 7

Multiple Choice

Two strings are made of the same material. String 1 has radius r1 while string 2 has radius r2 = r1/2. When stretched by the same tension, the respective speed of propagation of waves v1 and v2 satisfy the condition


A) v1 = Two strings are made of the same material. String 1 has radius r<sub>1</sub> while string 2 has radius r<sub>2</sub> = r<sub>1</sub>/2. When stretched by the same tension, the respective speed of propagation of waves v<sub>1</sub> and v<sub>2</sub> satisfy the condition A) v<sub>1</sub> = v<sub>2</sub>. B) v<sub>1</sub> = 2v<sub>2</sub>. C) v<sub>1</sub> = v<sub>2</sub>/ . D) v<sub>1</sub> = v<sub>2</sub>/2. E) v<sub>1</sub> = v<sub>2</sub>/4. v2.
B) v1 = 2v2.
C) v1 = v2/ Two strings are made of the same material. String 1 has radius r<sub>1</sub> while string 2 has radius r<sub>2</sub> = r<sub>1</sub>/2.
