2022-03-09 15:12:30 Why do house lizards hate egg shells?

If you place cracked eggshells around the house, in corners, and in windows, the occurrence of lizards should decrease noticeably. 

Lizards associate the broken shells with larger predators such as birds and larger reptiles.

2022-03-08 12:34:23 Why does the liquid part of the egg become solid when we boil it?

But when an egg is boiled or heated, the heat causes to make a longer and stronger chain of protein molecules and becomes unfolded.

2022-03-08 05:15:08 How Long Does it Take Sunlight to Reach the Earth?

In space, light travels at 300,000 kilometres (186,000 miles) per second.

Even at this breakneck speed, covering the 150 million odd kilometres (93 million miles) between us and the Sun takes a considerable time.

And eight minutes is still very little compared to the five and a half hours it takes for the Sun's light to reach Pluto.

2022-03-02 08:54:02 Can you walk if there is no friction?

You could not walk without 
the friction between your shoes and the ground.

As you try to step forward, you push your foot backward. Friction holds your shoe to the ground, allowing you to walk.

Consider how difficult it is to walk on slippery ice, where there is little friction. Walking without friction is like walking on a treadmill, you won't be able to go anywhere, but just slip on the same exact position.

Matter of fact, that you won't be able to walk on even a treadmill. But only humans won't be affected, even the animals would be affected and for some like snakes, moving is impossible.
