Answer:

Normal force, N = W_s - F

Explanation:

Let w_s is the weight of suitcase. A man attempts to pick up his suitcase by pulling straight up on the handle. The weight of the suitcase in downward direction. The normal force is acting in upward direction. Let F is the force with which it is pulled straight up.

So, the normal force is given by :

N = W_s - F

N = mg - F

mg is the weight of the suitcase.

Hence, this is the required solution.

How does a shorter wavelength affect the frequency of a wave?
mariarad [96]
<span>The product of (wavelength) x (frequency) is always the same number ... the speed of the wave. So if one of them decreases, the other one must increase in order to keep the product the same. Shorter wavelength means higher frequency. </span>

zzz [600]

Answer

The wavelength for 550 kHz signal is

             \lambda = \dfrac{3.00 \times 10^8}{550\times 10^3}

                         λ = 545.45 m

The wavelength for 1600 kHz signal is

              \lambda = \dfrac{3.00 \times 10^8}{1600\times 10^3}

                         λ = 187.5 m                        

The wavelength for 88 MHz signal is

              \lambda = \dfrac{3.00 \times 10^8}{88\times 10^6}

                         λ = 3.41 m

The wavelength for 108 MHz signal is

             \lambda = \dfrac{3.00 \times 10^8}{108\times 10^6}

                         λ = 2.78 m
