Part of the scientific process involves sharing your results with other scientists. To do this, we all need to use the same measurement system, which you'll learn about in this lesson.
Imagine you're trying to find out how much an elephant weighs. You're pretty sure it weighs a lot, but you don't know the exact number. So you ask your teacher, and she tells you an elephant weighs the same as three hippos.
Well that's nice to know, but how much does a hippopotamus weigh? Again, you ask your teacher, and she tells you a hippopotamus weighs the same as five alligators. That's a cool fact to know, but you still don't understand how much an elephant weighs because comparing elephants to alligators can be confusing.
plz mark me as brainliest :)
Answer:
The second law of a vibrating string states that for a transverse vibration in a stretched string, the frequency is directly proportional to the square root of the string's tension, when the vibrating string's mass per unit length and the vibrating length are kept constant
The law can be expressed mathematically as follows;
![f = \dfrac{1}{2\cdot l} \cdot \sqrt{\dfrac{T}{m} }](https://tex.z-dn.net/?f=f%20%3D%20%5Cdfrac%7B1%7D%7B2%5Ccdot%20l%7D%20%5Ccdot%20%5Csqrt%7B%5Cdfrac%7BT%7D%7Bm%7D%20%7D)
The second law of the vibrating string can be verified directly, however, the third law of the vibrating string states that frequency is inversely proportional to the square root of the mass per unit length cannot be directly verified due to the lack of continuous variation in both the frequency, 'f', and the mass, 'm', simultaneously
Therefore, the law is verified indirectly, by rearranging the above equation as follows;
![m = \dfrac{1}{ l^2} \cdot \dfrac{T}{4\cdot f^2} }](https://tex.z-dn.net/?f=m%20%3D%20%5Cdfrac%7B1%7D%7B%20l%5E2%7D%20%5Ccdot%20%5Cdfrac%7BT%7D%7B4%5Ccdot%20f%5E2%7D%20%7D)
From which it can be shown that the following relation holds with the limits of error in the experiment
m₁·l₁² = m₂·l₂² = m₃·l₃² = m₄·l₄² = m₅·l₅²

Answer:
![\lambda=0.57m](https://tex.z-dn.net/?f=%5Clambda%3D0.57m)
Explanation:
The distance traveled by the sound wave between the beats of the wing is its wavelength, since it is defined as the distance traveled by a periodic disturbance that propagates in a cycle, is defined as:
![\lambda=\frac{v}{f}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7Bv%7D%7Bf%7D)
Where v is the speed of sound and f the frequency of the wing beats
![\lambda=\frac{340\frac{m}{s}}{600Hz}\\\lambda=0.57m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B340%5Cfrac%7Bm%7D%7Bs%7D%7D%7B600Hz%7D%5C%5C%5Clambda%3D0.57m)
Answer:
approximately 35,786 km
Explanation:
A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level. It maintains the same position relative to the Earth's surface.
