Answer:
Explanation:
The relation between average velocity of a gas molecules and its molecular mass is as follows .
average velocity v
where k is a constant .
If v₁ and v₂ be the velocities corresponding to molecular masses 349 and 352 .
= 1.004
Answer:Quantitative data are data which are measured through direct sources of measurements; this means that we can observe them directly and measure them directly with the tools we're using. An example of this would be measuring the length of a football stadium with a measuring tape. Another would be measuring weight with a scale.hope it helps
Explanation:
Answer and Explanation:
Meteorologists use meteorological data to assess current temperature and precipitation rates and even make projections of these rates in future times. If high temperature rates combined with low rainfall can cause catastrophic fires to occur, then analyzing data on these factors and making projections on them is essential to prepare for those fires.
