Answer:
"Emergency resource guidebook" would provide you with the best initial information about this chemical
Explanation:
This guidebook is for the first responders in case of the beginning of any dangerous goods or the hazardous materials transportation incident. It is used in firefighters, paramedics and for the police officers, in countries like Canada, Mexico and also in the United states when responding to these accident cases becomes delay. The book has different colours in it, for chemicals it will be green colour whereas the blue or the yellow colour shows the toxic inhalation materials. In TIH it has initial isolation distance and protective action distance information against the accident. The white is the host specific.
Answer: The given statement is false.
Explanation:
Lightening is defined as steady expansion of air within and surrounding path due to the sudden increase in pressure and temperature that leads to emission of lightning.
Basically, lightning is a state of plasma in which the molecules are very rapidly striking with each other as it also contains positively charged ions and negatively charged electrons.
Lightning always leads to the production of thunder.
Therefore, we can conclude that the statement not every lightning strike produces thunder, is false.
S=d/t
speed can be calculated by dividing distance by time.
Answer:
Gravity on the moon, g = 1.69 m/s²
Explanation:
It is given that,
Length of pendulum, l = 1 m
Time period, T = 4.82 seconds
We have to find the gravity of the moon. The time period of the pendulum is given by :
g = acceleration due to gravity on moon
g = 1.69 m/s²
Hence, the gravity on the moon is 1.69 m/s².
