It's false i hope this helps :)
Nitrogen is essential to life. It is a component of all proteins and can be found in all living organisms. Nitrogen in the atmosphere. <span>The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with bean plants.</span>
First we determine the motor's efficiency - a ratio of the mechanical output power and the electrical input power:
The output mechanical power is directly proportional to torque and angular speed. From this relationship we can isolate the torque:
whereby the last expression uses the angular speed in rpm units.
(a) we calculate the torque, given that the motor draws 1.2 times the rated current, i.e., 48 Amps:
(b) use formula for the acceleration time:
The startup time will be 0.74s
Answer:
The correct answer is -
A (the entire green box): Chemical Equation
B (the blue box): Reactants
C (the arrow): Reacts to Form
D (the number): Coefficient
E (the purple box): Products
Explanation:
The chemical reaction of burning methane and oxygen is as follows;
Here, the green part A is the chemical equation that includes various parts that are reactants B, methane, and oxygen, C is an arrow that indicates the formation of products.
2 is here coefficient that indicates the moles of the oxygen which forms carbon dioxide and water in box E is products
