A perfectly spherical balloon of air is tethered to the floor of a stagnant body of water by cable AB, and sits just below the s
storchak [24]

To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.

By Newton's second law we understand that,

F = ma

Where,

m = mass

a = acceleration (at this case the gravity acceleration)

In the case of density, we know that it is described as the proportion of mass versus volume, that is,

\rho = \frac{m}{V}

Where,

m = mass

V = Volume

The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,

F_t = F_u - F_w

F_t =m_wg - m_a g

Mass can be expressed as,

F_t = \rho_w(\frac{4}{3}\pi r^3)*g -\rho_a(\frac{4}{3}\pi r^3)*g

F_t = (1000))\frac{4}{3}\pi 0.53^3)*9.8 -(1.225)(\frac{4}{3}\pi 0.53^3)*9.8

F_t = 6103.94N

Therefore the tension in cable AB is 6103.94N

Ruff, the 50 cm tall Labrador Retriever stands 3 m from a plane mirror and looks at his image. What is Ruff’s image position and
sertanlavr [38]
Since the mirror is plane, the image will be formed behind the mirror. The distance will be the same as that of the distance of the object from the mirror and the height will just be the same.
So, Ruff's image will be 3 m behind the mirror and 50 cm tall.

What are the application of total internal reflection​
coldgirl [10]

Answer:

Applications of Total Internal Reflection of Light: The phenomenon of total internal reflection of light is used in many optical instruments like telescopes, microscopes, binoculars, spectroscopes, periscopes etc. The brilliance of a diamond is due to total internal reflection.
