"He then pours the metal into a mold and allows it to solidify."
Answer:
True. 18-year old teenagers that practice some sport or have a hobby have less references to substance abuse or violence.
Explanation:
When someone practices a certain sport, he/she is occupied with its sport, also, sports encourage responsability, discipline and takes most of the person´s time and energy. People who doesn´t practice sports or have any hobby have more idle time and is always looking for something to take away the boredom. Most of the cases they start doing drugs or start having violent episodes because is what´s more handful and gives them the dopamine that the sport is not giving them (because they don´t practice any).
This is way the display of sports or hobbies involvements is associated with decreased references to risky behavior.
Answer:
The given blanks can be filled as given below
Voltmeter must be connected in parallel
Explanation:
A voltmeter is connected in parallel to measure the voltage drop across a resistor this is because in parallel connection, current is divided in each parallel branch and voltage remains same in parallel connections.
Therefore, in order to measure the same voltage across the voltmeter as that of the voltage drop across resistor, voltmeter must be connected in parallel.
Based on the average velocity at section 2, and the absolute pressures at both sectors, the average speed at section 1 is 2.226 m/s.
<h3>What is the average speed at section 1?</h3>
Density at P₁:
= (40 + 100) / (0.287 x (40 + 273))
= 1.5585 kg/m³
Density at P₂:
= (10 + 100) / (0.287 x (40 + 273))
= 1.2245 kg/m³
The average speed at section 1 is:
= (Density at P₂ x d² x 25.5) / (Density at P₁ x 9d²)
= 2.226 m/s
