Speed of the wave is 4 m/s

Explanation:

Wavelength of the rope is given to be 2 m. It measures the distance between two successive crests or troughs of the wave. Frequency is 2 Hz. Speed of the wave is given by

v = f × λ, where f is the frequency and λ is the wavelength.

⇒ v = 2 × 2 = 4 m/s

Physics

2:1

Explanation:

It is given that,

The diameter of a white blood cell is 12 micrometers

The diameter of white blood cell according to a model is 24 micrometers.

We need to find the ratio of model size to actual size. It can be done as follows :

$R=\dfrac{\text{model size}}{\text{actual size}}\\\\R=\dfrac{24\ \mu m}{12\ \mu m}\\\\R=\dfrac{2}{1}$

Hence, the ratio of model size to actual size is 2:1.
