Why sometimes we wake up with a headache ?!​

Answer:

Answer is 9

Step-by-step explanation:

4765 ____ 2. Thus, The smallest digits to be placed in blank space = 0. Then, sum = 24 + 0 = 24, which is divisible by 3. The greatest digit to be placed in blank space = 9.

Answer:

The correct answer is Option: D

Explanation:

We know that equal and opposite forces cancel out each other. So in the case 1, the resultant force will be zero.

In case 2, both the forces (2N and 3N) are being applied in the same direction so they will add up and the resultant force will become 5N towards right direction.

Now, in the 3rd case, both forces are being applied in the opposite direction but the force towards the right direction is greater than that in left direction(3N>2N). So the resultant force will become 1N towards right direction.

So, the correct answer is Option: D

Answer: Option d

Explanation:

Answer:

water has a very high tendency

Answer:

Chemical properties of water . water reacts with a lot of substances to from different compounds some significant reactions are as follows :

Amphoteric nature : water can act as both acid and base , which means that it is amphoteric in nature

Redox reactions : Electropositive elements reduce wate to hydrogen molecule .This water is a great source of hydrogen . Let us see an example in this case :

2H20(1)+2Na(s)2NaOH(aq)+H2(g)

During the process of photosynthesis ,water is oxidized to O2 . As water can be oxidized and reduced it is very useful in redox reactions

Hydrolysis reaction : water has a very strong hydrating tendency due to its dielectric constant . It dissolves many ionic compounds can be hydrolyzed in water
