What is wavelength ?
The distance over which a periodic wave's shape repeats is known as the wavelength in physics. It is a property of both traveling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda () is frequently used to represent wavelength. The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.

Answer:
The answer to your question is: F = 0.4375 N. The force will be 16 times lower than with the first conditions.
Explanation:
Data
F = 7 N
F = ? if the masses is quartered
Formula
![F = \frac{Km1m2}{r2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7BKm1m2%7D%7Br2%7D)
Process
Normal conditions F = Km₁m₂/r² = 7
When masses quartered F = K(m₁/4)(m₂/4)/r² = ?
F = K(m₁m₂/16)/r²
F = K(m₁m₂/16r² = 7/16 = 0.4375 N
Answer:Done doing there job, in the winter they have a break

Answer:
605447.7066 kgm²/s
Explanation:
= Mass of sphere = 10000 kg
= Mass of rod = 10 kg
r = Radius of sphere = 2 m
l = Length of antenna = 3 m

Angular momentum is given by
![L=I\omega](https://tex.z-dn.net/?f=L%3DI%5Comega)
Moment of inertia of the satellite is

![I_a=\frac{1}{3}m_2l^2](https://tex.z-dn.net/?f=I_a%3D%5Cfrac%7B1%7D%7B3%7Dm_2l%5E2)
The angular momentum of the system is
![L=I_s\omega+I_a\omega\\\Rightarrow L=\left(\frac{2}{5}m_1r^2+2\times \frac{1}{3}m_2l^2\right)\omega\\\Rightarrow L=\left(\frac{2}{5}10000\times 2^2+2\times \frac{1}{3}\times 10\times 3^2\right)\times 37.69911\\\Rightarrow L=605447.7066\ kgm^2/s](https://tex.z-dn.net/?f=L%3DI_s%5Comega%2BI_a%5Comega%5C%5C%5CRightarrow%20L%3D%5Cleft%28%5Cfrac%7B2%7D%7B5%7Dm_1r%5E2%2B2%5Ctimes%20%5Cfrac%7B1%7D%7B3%7Dm_2l%5E2%5Cright%29%5Comega%5C%5C%5CRightarrow%20L%3D%5Cleft%28%5Cfrac%7B2%7D%7B5%7D10000%5Ctimes%202%5E2%2B2%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%5Ctimes%2010%5Ctimes%203%5E2%5Cright%29%5Ctimes%2037.69911%5C%5C%5CRightarrow%20L%3D605447.7066%5C%20kgm%5E2%2Fs)
