The speed of surface waves in water decreases as the water becomes shallower. Suppose waves travel across the surface of a lake
Elanso [62]

Answer:

The correct solution is "1.2 m".

Explanation:

The given values are:

Wavelength of waves,

λ = 1.5 m

Speed of waves on surface,

V = 2 m/sec

Speed of waves in water,

V₁ = 1.6 m/sec

As we know,

⇒  V=f\times \lambda

or,

⇒  f=\frac{V}{\lambda}

On substituting the values, we get

⇒      =\frac{2}{1.5}

⇒      =1.33 \ Hz

hence,

⇒  \lambda_1=\frac{V_1}{f}

On substituting the values, we get

⇒       =\frac{1.6}{1.33}

⇒       =1.2 \ m

A boy rows a rowboat across a river. The boat moves at 4.3 m/s at a direction of 25°
NikAS [45]

East component: 3.9 m/s

South component: 1.8 m/s

Explanation:

We have to resolve the velocity vector along the east and south axis.

Taking east as positive x-direction and south as positive y-direction, the components of the velocity are given by:

v_x = v cos \theta\\v_y = v sin \theta

where

v = 4.3 m/s is the magnitude of the velocity

\theta=25^{\circ} is the angle between the direction of the velocity and of the x-axis

Substituting into the equations, we find:

East component:

v_x = (4.3)(cos 25^{\circ})=3.9 m/s

South component:

v_y = (4.3)(sin 25^{\circ})=1.8 m/s
