Answer:
F = V / T
=
= 42ml/hr
Explanation: first convert time into hours,then deduce the formula for the flow rate
Neutrons are responsible for combining with protons in the nucleus together to be held by the strong force. Too many neutrons in an atom will result in radioactive decay due to the neutrons' force overpowering the strong force.
Answer:
Data Scientist
Explanation:
Data Scientist (different from a statistician) is a type of researcher that uses computer softwares to analyse and make sense of raw digital data.
Data Scientists usually combine knowledge of computer science, statistics and mathematics while using various softwares to extract information and meaningful, key insights (whether structured or unstructured) from data.
There are two popular types of data scientists: Operational Data Scientists (experts in software implementations and day to day running of the data science wing of a firm) and Exploratory Data Scientists (The real digital data miners, the researchers).
With the way the world is set up now that data is everything, data scientists are a must for every firm as the raw data every firm collects is processed by data scientists.
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
Potassium is an alkali metal with the chemical symbol K. It has an atomic number of 19, meaning that it has 19 positively charged protons. It also contains 19 electrons, which have a negative charge, and 20 neutrons, which do not hold a charge
