The answer is 51.0 ml but can someone explain why please
professor190 [17]

Answer:

\boxed{\sf A. \ 51 \ mL}

Explanation:

Amount of water displaced by the sphere will be equal to the volume of complete sphere.

As the sphere completely sinks to the bottom of the cup.

We have been given;

Diameter of sphere (d) = 4.6 cm

So,

\sf Radius \:  of \:  sphere  \: (r) =  \frac{Diameter \:  of \:  sphere \: (d)}{2}  \\  \sf =  \frac{4.6}{2}  \\ \sf  = 2.3 \: cm

Volume of sphere (V):

\boxed{ \bold{V =  \frac{4}{3} \pi {r}^{3} }}

By substituting value of r we get:

\sf \implies V =  \frac{4}{3}  \times \pi \times  {(2.3)}^{3}  \\  \\  \sf \implies V =  \frac{4}{3}  \times 3.14 \times 12.167 \\  \\ \sf \implies V =    \frac{152.81752}{3} \\  \\   \sf \implies V =  50.94 \:  {cm}^{3}  \\  \\   \sf \implies V  \approx 51 \:  {cm}^{ 3}

1 cm³ = 1 mL

\therefore

V = 51 mL

So,

Water displaced by the sphere = 51 mL

What happens to the actual image you see between the time you see it and it your brain registers it?
USPshnik [31]

Answer AND Explanation:

As light reflected from an external object enters the eye, it is refracted by the cornea, aqueous humour, the lens and vitreous humour so that an image is focused on the retina. The image is real, upside down and smaller than the object. The photoreceptor cells are stimulated by the reflected light and impulses are set off. The impulses are transmitted by neurons through the optic nerve to the optic region of the brain. The brain interprets the impulse as an upright impression of the object.
