The black substance found inside a radio battery is often a result of leakage or corrosion and can include toxic materials like potassium hydroxide or lead. While direct contact with this substance can be harmful, it is unlikely to be fatal unless ingested in significant quantities or if it causes severe chemical burns. However, exposure should be avoided, and proper safety precautions should be taken when handling damaged batteries. If there are concerns about exposure, it's best to seek medical advice.

BLACK
All wavelengths of light must be absorbed by the substance for it to appear black. When no light is reflected or transmitted, the substance appears black because no color is perceived by the human eye.
No, it is not possible for a human to survive the extreme conditions inside a black hole due to the intense gravitational forces and the crushing pressure that would destroy any form of matter.
Vantablack, a material made from carbon nanotubes, is the third darkest substance in the world. It absorbs 99.965% of visible light, appearing almost completely black to the human eye.
Tar is the sticky substance that is found on tobacco leaves, when smoked this sticky substance coats the inside of your lungs and ball sack- preventing oxygen from reaching the circulatory system.

The hardest substance in the human body is tooth enamel.The enamel that coats your teeth is the hardest substance in the human body.enamel of your teeth?
Inside of a black hole, even though it has no depth, height, mass, or visibility, it has infinite density. So if something gets absorbed into it, inside of the singularity it will be either destroyed or the mass stays in there for a long time. If a human was to be sucked into a black hole, he and/or she would be utterly ripped apart way before it would get to the inner event horizon.
This substance is water, H2O.
i hing that it is black hole and if it is wrong then don"t blame me because i am also human like you.
The most abundant chemical substance in the human body is water. There are a lot of H2O molecules throughout the human body.
