'Bang/POP'.
If there is any oxygen near, then the hydrogen will ignite with a 'POP'.
Incidence is a key epidemiological measure that measures the rate of new cases of a specific disease within a population during a defined time period, indicating the risk of developing the condition. It is expressed as a rate or proportion. On the other hand, prevalence represents the total number of cases, both new and existing, at a specific point in time, offering a snapshot of the overall burden of the disease in the population. Prevalence is expressed as a proportion or percentage. For example, there are 500 cases of a disease in a population of 10,000 people at a specific time, the prevalence would be calculated as 5%.
Both measures play essential roles in epidemiology, providing different perspectives on the occurrence and impact of diseases in a community.
Moreover, if anyone is looking to learn and gain in depth understanding of this subject, should consider opting this online course – Community Medicine for UnderGrads by Dr Bratati Banerjee,**** a faculty at Maulana Azad Medical College(MAMC) on DigiNerve.
This course comprises well illustrated video lectures, detailed notes and Self-assessment questions, helping students with a comprehensive learning journey from acquiring in depth knowledge & understanding to evaluating you learning by mcqs and feel confident.
I highly recommend this course to every student in this area, also available at a cheap price.
Test tubes, beakers and pipettes, among other things, are used to hold small amounts of liquid in a science lab.
It is Newton's first law of universal dynamics.
More correctly written as ' A body will remain in uniform motion unless acted upon by a force'.
I leave you to find the other two Newtonian Laws of Universal Dynamics.

Because there is a large component of calcium carbonate in the egg shell.
Remember
Acid + Carbonate = Salt + Water + Carbon Dioxide.
2CH3COOH + CaCO3 = Ca(CH3COO)2 + H2O + CO2
2. materials:

3. Hypothesis.I think that a nail rust faster in salt water because of the chemicals in the salt.
4. Procedure:
inde variable:same nail and fresh and salt water
dep variable:how many days will it take
con varable:size of nail,different water

A) Inferential statistics deals with collecting, summarizing, and simplifying data about given population
B) Descriptive statistics is also known as inductive statistics
C) Descriptive statistics goes beyond describing a given problem situation by means of collecting, summarizing and meaningfully presenting the related data
D) Descriptive statistics is one which describes the population. On the other hand, inferential statistics issued to make the generalization about the population based on the samples.

No. An hypothesis is an idea put forward to explain an observation. Often you do the experiment to test the hypothesis. The results of the experiment may help you decide whether to discard your hypothesis or to test it further.
this is a simple question... I believe that the theoretical value for the linear expansion of steel is extremely simple. Ask a science teacher and they will be able to help you. If you go to the library you can borrow a book on this subject. I hope i helped you in your mission. Thank you very much for your time.
Have an excellent life.
i hope u get an answer.

One practical use to a metallic change is to obtain a purified form of the more active and or valuable metals. We do this through electrolysis.
The dependent variable is what the results yielded. For example, if you are testing humans, the dependent variable will be the test subject's answers. Some people also say it is what you are testing for if it is not testing on humans. For example, "the differences in growths of bacteria".
