Question:
A high ____will have a short wavelength
Answer:
That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths
Explanation:
Hope it help
Explanation:
It is given that,
Velocity of the particle moving in straight line is :
![v(t)=t^2e^{-2t}\ m/s](https://tex.z-dn.net/?f=v%28t%29%3Dt%5E2e%5E%7B-2t%7D%5C%20m%2Fs)
We need to find the distance (x) traveled by the particle during the first t seconds. It is given by :
![x=\int\limits {v.dt}](https://tex.z-dn.net/?f=x%3D%5Cint%5Climits%20%7Bv.dt%7D)
![x=\int\limits {t^2e^{-2t}dt}](https://tex.z-dn.net/?f=x%3D%5Cint%5Climits%20%7Bt%5E2e%5E%7B-2t%7Ddt%7D)
Using by parts integration, we get the value of x as :
![x=\dfrac{-(2t^2+2t+1)e^{-2t}}{4}\ meters](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-%282t%5E2%2B2t%2B1%29e%5E%7B-2t%7D%7D%7B4%7D%5C%20meters)
Hence, this is the required solution.
Answer:
High density D answers to your questions
Answer:
b, a, c
Explanation:
The middle one has the shortest wavelength, then it's the top one and the last one has the longest wavelength.
Answer:
F = 19.1 N
Explanation:
To find the force exerted by the string on the block you use the following formula:
(1)
k: spring constant = 95.5 N/m
x: displacement of the block from its equilibrium position = 0.200 m
you replace the values of k and x in the equation (1):
![F=(95.5N/m)(0.200m)=19.1N](https://tex.z-dn.net/?f=F%3D%2895.5N%2Fm%29%280.200m%29%3D19.1N)
Hence, the force exterted on the block is 19.1 N
