pls correct false statement
no spamming pls
Answers
1)Light travel faster than sound
2)oxygen is supporter for combustion
3)true
4)true
5)true because of porous sound is not able to reflect
Step-by-step explanation:
1. Sound travels fast
The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. ... No information can propagate faster than the speed of light.
A good fuel should have a high ignition
temperature. falseer than light.
Ideal fuel should have a proper ignition temperature, so that it can be burned easily. The ignition temperature of an ideal fuel should neither be too low nor too high. If the ignition temperature of the fuel is very low, then the fuel will catch fire too easily and hence it will be very unsafe to use it. On the other hand, if the ignition temperature is too high, then it will be very difficult to light the fuel.
