મગજ કસે તેવા કેટલાક કોયડા….. પહેલા વિચારો પછી જ જવાબ જોવો

 

મગજ કસે તેવા કેટલાક કોયડા….. પહેલા વિચારો પછી જ જવાબ જોવો

Science is a subject based on questions and curiosities. The first question arises inside a person about things and then he tries to find the answer to that question. When man saw birds flying in the air, he wondered why he could not fly and thus built a ship. In this order, answers were found to many questions like how much does the earth weigh or why only the sun appears in all the stars during the day..

What is the weight of the sky?

The surface area of ​​the earth is 19.7 million square miles. Multiply that by 4 billion, that would be the surface area of ​​the sun. Atmospheric pressure is about 6.6 kilograms per square inch. So in this way the Sun weighed 52 lakh billion metric tons. According to the Science and Technology Facilities Council of the United Kingdom, it can also be measured in the weight of Indian elephants. According to that, the weight of the sky would be equal to the weight of the sun equal to the weight of 5.7 lakh billion adult Indian elephants.

How does an airplane fly in the air?

Airplanes fly in the air because of the shape of their wings. The air blowing over the fan is sent by pushing it downwards which in turn pushes the wing or fan upwards. This push is stronger than gravity, because of this the airplane flies in the air.

How is a rainbow formed?

White is a combination of many colors. When light passes through a prism, it divides into seven different colors. After the rain a few drops of water remain in the fissure which acts as a prism. When light passes through it it splits into seven colors and we see a strip of seven colors called a rainbow.

Sometimes two rainbows appear. Two rainbows appear when the droplets present in the same place are repeatedly exposed to the sun. As the colored light emitted from the first rainbow changes to white, so does its contact with other droplets and then the light is scattered in different colors, but its colors are in reverse order.

Why do birds not get electric current even when sitting on the wire?

What is the weight of the earth?

The weight of the earth is 5.972×1024 kilograms. Well technically the weight of the earth is nothing because the cause depends on the gravitational pull applied to an object and the earth is floating in space. Yet mathematicians have made this assessment by looking at the gravitational pull applied by the earth to nearby objects.

Why do birds not get electric current even when sitting on the wire?

 

જવાબ જોવા માટે અહી ક્લિક કરો

The flow of electricity is from live phase to neutral. This means that you will feel the current only when you are touching a positive wire and also a negative or neutral wire (or ground). If a bird is touching the ground as well as the wire, then the ground will act as a neutral wire and the flow of electricity will be in the body of the bird which will give it an electric shock. If the bird sits on a single wire and touches the metal or any other wire of the pylon, then the circuit will be completed and it will get an electric shock. But usually the birds just sit on a wire which is why they do not feel the current.
