Speed (m/s) = distance (metres) ÷ time (seconds)
For Track 1: 0.2 ÷ 2 = 0.1m/s
For Track 2: 0.2 ÷ 2 = 0.1m/s
For Track 3: 0.6 ÷ 6 = 0.1m/s
For Track 4: 0.4 ÷ 6 = 0.07m/s
The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.
Answer:
A mixture is just a combination of things, like air (made up of different but distinct gasses), or toothpaste, where compounds are physically mixed together but stay fundamentally what they started as. If there is a chemical change, like hydrogen and chlorine gas reacting to form hydrochloride acid, then it is known as a new compound.
Answer:
The answer is "4,241 .17 years"
Explanation:
The disintegration rate, which shows in C-14 atoms =
Rate of sample disintegration =
The digit proportion of C-14 can be determined that is included in the sample
5730 years from half-life.
The number with half-lives (n) which are repelled must be determined:
So, the age of the sample is given by =
