Answer:
There isnt enough in your question to answer the question bro, like we need a picture or something bro.
Explanation:
Gamma: 4
Infrared: 1
X-Ray: 3
Visible Light: 2
Infrared has the longest wavelength between the four options, meaning that it has the lowest frequency. Since the longer the frequency, the lower the frequency. While the shorter the wavelength, the higher the frequency.
Next would be visible light since it has the second longest wavelength out of the given options. Then it would be X-Ray. And finally Gamma since it has the shortest wavelength.
Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
Answer:
k = 22.05 N/m
Explanation:
The potential energy of the mass is converted into potential energy of the spring.
Given:
mass m = 0.27 kg
gravitational constant g = 9.8 m/s²
distance falling/ stretching of spring h = 0.24 m
![U_{gravity} = U_{spring}\\ mgh = \frac{1}{2} kh^{2}](https://tex.z-dn.net/?f=U_%7Bgravity%7D%20%3D%20U_%7Bspring%7D%5C%5C%20mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20kh%5E%7B2%7D)
Solving for k:
![k = 2mg\frac{1}{h}](https://tex.z-dn.net/?f=k%20%3D%202mg%5Cfrac%7B1%7D%7Bh%7D)
