The correct answer to the question is : Light or any electromagnetic wave.

EXPLANATION :

Before going to answer this question, first we have to understand refraction.

Refraction is the optical phenomenon in which light ray will bend at the interface of the two media having different optical densities.

When light ray comes from optical rarer medium to optical denser medium, the ray will bend towards the normal. It is so because the velocity of light in rarer medium is more than velocity of light in denser medium.

When the light comes from optical denser medium to optical rarer medium, the light ray bends away from the normal. It is so because the velocity of light increases in the rarer medium.

As per the question, wave is moving from air to ocean, and its velocity slows down.

Hence, there is refraction. So, the wave must be light or any electromagnetic wave.

Answer:

(a) Most reactive ${}$ Metal B

${}$ Metal D

${}$ Metal A

Least reactive ${}$ Metal C

(b) (i) Bubbles should form very slowly

(ii) No reaction takes place

Explanation:

(a) The given metals arranged in their order of reactivity are;

Most reactive ${}$ Metal B

${}$ Metal D

${}$ Metal A

Least reactive ${}$ Metal C

The other of reactivity is based on the nature of their reactivity of the metals in air

(b) (i) Based on the reactivity of the metals in air, whereby metal A reacts very slowly and an oxide is formed, we have that, based on the reactivity of the metal A, when mixed with dilute hydrochloric acid, bubbles should form very slowly

(ii) Similarly, given that metal C is unreactive, we have that when small pieces of metal C are added to dilute hydrochloric acid, no reaction takes place.

If a train travels 500 kilometers from Stockholm to

o-na [289]

Hello,

Average speed is total distance divided by total time. From the problem, our total distance is given as 500 kilometers and given time is 5 hours. Therefore, the average speed is:

$\displaystyle{v_\text{average}=\sum_{i=1}^n \dfrac{s_i}{t_i}}\\\\\displaystyle{v=\dfrac{500\ \text{km}}{5 \ \text{h}}}\\\\\displaystyle{v=100 \ \text{km/h}}$

Therefore, the average speed is 100 km/h. Please let me know if you have any questions!

How do the groups of the periodic table correspond

hichkok12 [17]

They correspond due to the fact that certain elements are grouped together based on the number of valence electrons on the outer shell of their electron configuration.
For instance, sulfur (S) has 6 electrons in the outer shell, as it is in the 6th group EXCLUDING transition metals (note, never take these into account, as their charge is always +2; a cation)
