The wave speed in a guitar is 260 m/s. what is the length of the string 74cm

the formula for calculating the wave speed is v=fT

v is velocity

f is frequency

T is Landa

260=f÷(74÷100)

260=f÷0.74

f=260÷0.74

f=351.35Hz

I am pretty sure of my answer and that's if your question is really talking about the frequency

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
