A biker can ride at 12 m/s on a level road when there is no wind and at 7.5 m/s on a level road when there is a head wind of 5 m
alexandr402 [8]

Answer:

The answer is "1.94 \ m^2".

Explanation:

Formula:

F= \frac{1}{2} \times C_D \times density \times area \times  velocity^2\\\\Power (P) = F \times velocity \\\\P = \frac{C_D}{2} \times density \times area \times  velocity^3\\

Given value:

\ P = 10.25 \ W \\\\\ density = 1.2 \ kg/m^3 \\\\\ velocity= 2.5 \\\\

10.25 = \frac{C_D A}{2} \times 1.2 \times 2.5^3\\\\C_D A= \frac{10.25 \times 2 }{1.2 \times 2.5^3}\\\\C_D A = 1.94 m^2\\

5. What is the amplitude and wavelength of the wave?
scZoUnD [109]

Answer:

Amplitude = 5 cm

Wavelength = 30 m

Explanation:

Amplitude is the maximum displacement. According to the graph, the maximum height is the maximum displacement which is equal to 5cm.

Wavelength is the same distance between two successive Crest or trough.

From the graph the wavelength is 30 metres.

That is,

Amplitude = 5 cm

Wavelength = 30 m
