- The wavelength of the red light in "nanometer" is 7×
- Wavelength is given as : 7× meter
- 1 nanometer = ( meter)
- Let X= value of the wavelength in nanometer.
1 nanometer = meter
X nanometer = 7× meter
- <em>If we Cross multiply</em>
X nanometer = ()
X= 7× nanometer
Therefore, the wavelength in "nanometer" is 7×

Answer:
First of all the formula is F= uR,( force= static friction× reaction)
mass= 5+25=30
F= 50
R= mg(30×10)=300
u= ?
F=UR
u= F/R
u= 50/300=0.17N
