Answer:
The three quantitative characteristic properties of water is explained below in detail.
Explanation:
The three quantitative components of water incorporate the following:
1.Freezing point:
The water has a freezing point of 0 degrees Celsius.
2. Boiling point:
The water has a boiling point of 100 degrees Celsius.
3. Melting point:
The melting point of ice is 0 degrees Celsius.
These properties are all uncommon to water. Being uncommon means that these characteristics are only noticeable in water; hence, they can be beneficial in recognizing such a substance.
Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
Answer:
a parameter is fixed over time, while an exogenous variable is allowed to change over time.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
A variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited. Thus, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
An exogenous variable can be defined as a that's independent of other variables in a system i.e it's not affected by other variables.
This ultimately implies that, the difference between a parameter and an exogenous variable is that a parameter is fixed over time, while an exogenous variable is allowed to change over time and as such it has a relationship with other variables in a system.
