The human body has an average density of 979 kg/m3 , what fraction of a person is submerged when floating gently in fresh water?
FromTheMoon [43]

A person is submerged of about 97.9%.

The average density of the human body is given as 979 kg/ m³.

<h3>Define Law of floatation.</h3>

    Law of floatation can be defined as the volume of the liquid displaced when a body floats on the liquid surface is equal to the body submerged in the water.

As body has the stable equilibrium state, the buoyancy of the fluid will be equal to the weight.

Weight of the body floating = Weight of the body immersed in fluid

  Law of floatation = Density of the floating object / density of fluid

 As fluid is the freshwater here, the density of fluid will be 1000 kg/ m³.

                               = (979 kg/ m³) / ( 1000 kg/ m³)

                               = 97.9 %

A person is submerged when floating gently in fresh water about 97.9%.

When an object is placed just outside the focal length of a concave mirror, the image is
swat32

Answer:

O larger than the object and real

Explanation:

As we know by the formula of mirror

\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}

here we know that

d_o = (f_o + x)

so we have

\frac{1}{d_i} = \frac{1}{f_o} - \frac{1}{f_o + x}

so we have

d_i = \frac{(f_o)(f_o + x)}{x}

so magnification is given as

M = -\frac{d_i}{d_o}

M = - \frac{f_o}{x}

so here we have

|M| > 1

so image will be larger than object and real
