Refraction. When light is distorted when going through a substance like water, it is being refracted. 
aalyn [17]3 years ago
6 0

The answer to the question is Refraction.

EXPLANATION:

The spoon half dipped inside the water is appeared to be bent. This is due to the optical  phenomenon called refraction.

Refraction is the property of light by virtue of which light ray bends away or towards the normal at the point of incidence when it incidents obliquely at the refracting surface.

In the given figure, light rays are coming from air which is optically rarer medium as compared to water. So, the ray, after striking the air-water interface, gets bent towards the normal in the optically denser medium i.e water.  It is so because the velocity of light in optically denser medium is less as compared to rarer medium.

We view the object due to the light. As light rays are bent, so the spoon is appeared to be bent.

What happens in a global convection cell? apex​
zysi [14]

Answer:

In a global convection cell less –dense air at the equator rises and flows towards the poles. And from pole, the dense air sinks down and flows back towards the equator.... This movement of air is also supported by the Earth's rotation known as Coriolis Effect.

Perform the following calculations and give your answer with the correct number of significant figures
love history [14]

Answer:

see below

Explanation:

a. 0.1886 x 12 =2.2632

This has 2 sig figures so the answer can only have 2 sig figures

2.3

b. 2.995 - 0.16685 =2.82815

The most accurate in the problem is to thousands place so our answer can only be accurate to the thousands place

2.828

c. 910 x 0.18945=172.3995

The  least number of significant figures is 3 so the answer can only have 3 significant figures

A pebble is thrown into the air with a velocity of 19/m at an angle of 36 with respect to the horizontal.
kow [346]

Answer:

The maximum height the pebble reaches is approximately;

A. 6.4 m

Explanation:

The question is with regards to projectile motion of an object

The given parameters are;

The initial velocity of the pebble, u = 19 m/s

The angle the projectile path of the pebble makes with the horizontal, θ = 36°

The maximum height of a projectile, h_{max}, is given by the following equation;

h_{max} = \dfrac{\left (u \times sin(\theta) \right)^2}{2 \cdot g}

Therefore, substituting the known values for the pebble, we have;

h_{max} = \dfrac{\left (19 \times sin(36 ^{\circ}) \right)^2}{2 \times 9.8} = 6.3633894140470403035477570509439

Therefore, the maximum height of the pebble projectile, h_{max} ≈ 6.4 m.
