Solution:

If you notice the animated gif, you know that D, C and B are going to die. D dies directly after coming in contact with the object, C dies after being thrust by the spikes of the see-saw and B dies with the blue ball.

But consider the situation that the person at E stands for Ebola. Eventually A dies as well.

We thank 9gags for this awesome gif.

Solution:

You must have heard about the propelling force or the popular quote: 'every action has an equal and opposite reaction'.

Here, the man can throw his mobile phone with maximum force on one side and then he will be propelled to the other direction. He will then be able to glide to the other side and escape. The force will be very small but since the surface is frictionless, it will be enough for him.

Solution:

Now you must be aware of the fact that in general, the magnetic field is present only on the poles of the magnet. Thus keep any rod on a surface. Then hold the other rod in your hand and bring its tip close to the center of the rod that is lying down on the surface. If the rod comes close to the rod you are holding, then the one you are holding is a magnet. However, if the rod does not gets attracted towards your rod, then the one that is lying is the magnet.

Solution:

Solution:

Solution:

The iron brick will make the water level higher.

Explanation:
But on the contrary, in actual terms, none of them will help in rising the water. They will actually drop the water level. This is because, they have a large effect on the water level while in the boat but when they are dropped into the water. They will drop the water level. Iron brick being the lighter one will drop the water level less because it will have less effect on the water from the boat but will displace the equal amount of water as the gold when it is dropped into the water. Thus it can be said that it will make the water level higher.

Solution:

The correct answer to this twisted problem is four times.

You can try solving the problem with the help of two coins and if you are unable to understand, you may even disassemble some clockwork to find out.

Now to explain it, it is evident that the small one will turn 3 times against the big one. The reason is because it has 8 teeth which is 1/3 of the big one (24). But now we want the big wheel to stop and the small one to turn around the big one. In this process, the small one will make an additional turn on its way around the big one. This makes a total of four turns.

Solution:

Pedro Rodrigues Filho was Mass Murderer.

Density multiplied by volume equals mass.
Therefore, Pedro Rodrigues Filho killing mass would mean Pedro Rodrigues Filho was a MASS murderer

Solution:

If you are thinking 5 times powerful, then you are in a completely wrong direction. The answer will be the square root of ten i.e. 3.16.

Thus if it was half a point higher on the Richter scale, the earthquake will be 3.16 times more powerful.
