I think the correct answer from the choices listed above is the second option. The difference between speed and velocity would be that speed requires distance. Velocity requires displacement. Speed only has a magnitude while velocity is a vector quantity which means it has direction and magnitude.

Answer:

The frequency of this light is $6.98\times 10^{14} s^{-1}$ .

Explanation:

Wavelength of the light = $\lambda = 430 nm=4.30\times 10^{-7} m$

Speed of the light = c = $= 3\times 10^8 m/s$

Frequency of the light = $\nu$

$\nu =\frac{c}{\lambda }$

$\nu =\frac{3\times 10^8 m/s}{4.30\times 10^{-7} m}=6.98\times 10^{14} s^{-1}$

The frequency of this light is $6.98\times 10^{14} s^{-1}$ .

Explain the process and purpose of strip cropping

STatiana [176]

It is used when a slope is too steep or when there is no alternative method of preventing soil erosion. The most common crop choices for strip cropping are closely sown crops such as hay, wheat, or other forages which are alternated withstrips of row crops, such as corn, soybeans, cotton, or sugar beets.
