<span>A question is scientific when it can be answered by using logic and scientific information we have currently, or if there is scope for it to be answered in future because of further development in technology / theories. Scientific questions are based on facts that are observed, just like that of magnet attracting bits of iron, etc.
Few questions like existence of God / existence of demons are beyond science as they are not based on any observation.</span>
false a waist to hip ratio that is healthy would be .80 or less is considered healthy for most individuals hope this helps
Answer:
1.F is the electrostatic force between charges (in Newtons),
2.q₁ is the magnitude of the first charge (in Coulombs),
3.q₂ is the magnitude of the second charge (in Coulombs),
4.r is the shortest distance between the charges (in m),
5.ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C² .
Answer:
Wavelength, ![\lambda=0.011\ m](https://tex.z-dn.net/?f=%5Clambda%3D0.011%5C%20m)
Explanation:
Given that,
Number of cycles in a spiral spring is 2.91 in every 3.67 s
The velocity of the pulse in the spring is 0.925 cm/s, v = 0.00925 m/s
To find,
Wavelength
Solution,
Number of cycles per unit time is called frequency of a wave. The frequency of the longitudinal pulse is,
![f=\dfrac{2.91}{3.67}=0.79\ Hz](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7B2.91%7D%7B3.67%7D%3D0.79%5C%20Hz)
The wavelength of a wave is given by :
![\lambda=\dfrac{v}{f}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7Bf%7D)
![\lambda=\dfrac{0.00925\ m/s}{0.79\ Hz}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B0.00925%5C%20m%2Fs%7D%7B0.79%5C%20Hz%7D)
![\lambda=0.011\ m](https://tex.z-dn.net/?f=%5Clambda%3D0.011%5C%20m)
So, the wavelength of the longitudinal pulse is 0.011 meters. Hence, this is the required solution.
You use the equation Velocity = Acceleration X Time. 4x4=16m/s.
The car travels 18m in 3 seconds.
