Two ranger stations are on an east-west line 110 mi apart. A forest fire is located on a bearing of N 42º E from the western sta

tion at A and a bearing of N 15ºE from the eastern station at B. How far is the fire from the western station to the nearest mile?

Answer:

Explanation:

AB = 110 miles

Let the distance of the western station from fire is d.

As according to the diagram, use Sine law

\frac{d}{Sin 15}=\frac{110}{Sin 133}

d = 110 x 0.2588 / 0.73

d = 39 miles

Three liquids that will not mix are poured into a cylindrical container. The volumes and densities of the liquids are 0.50 L, 2.
Vladimir79 [104]

Answer:

The force is  F = 18.33 \  N

Explanation:

From the question we are told that

    The number of liquids is  n =  3

      The volume of the first liquid is V_1 = 0.50 L = 0.0005 \  m^3

      The density of the first liquid is  \rho_1  =   2.6 \ g/cm^3

      The volume of the second  liquid is V_2 = 0.25 L = 250\  cm^3

      The density of the second liquid is  \rho_2  =  1.0 \ g/cm^3

      The volume of the third  liquid is V_3 = 0.40 L = 400\  cm^3

      The density of the  third  liquid is  \rho_3  =  0.80 \ g/cm^3

Generally the force at the bottom of the container is mathematically represented  as

    F = m_t *  g

Here g = 980.665  \ cm/s^2

Here  m_t  is the total mass of all the liquid which is mathematically represented as

             m_t = ( V_1 *  \rho_1 )+ ( V_2 *  \rho_2)+ ( V_3 *  \rho_3)

=>         m_t = ( 500 *  2.6)+ ( 250 *  1.0 )+ ( 400  *  0.80 )

=>         m_t = 1870 \  g

So

       F = 1870  *  980.66

=>   F = 1833843.55 \ g \cdot cm /s^2

=>    F = 1833843.55 \ g \cdot cm /s^2 =  \frac{1833843.55}{1000 * 100} kg \cdot m /s^2

=>    F = 18.33 \  N
