Grease the blade via the remaining fitting after removing one of the two zerk fittings for the blade.
For almost a century, Hartzell has dominated the market for aviation propeller systems. For the greatest result for the aircraft designer modification, we provide over 400 various blade designs that may be set in hubs with 2- to 6-blades.
Robert N. Hartzell established the Hartzell Walnut Propeller Company, which later became the American company Hartzell Propeller, in 1917.
For certified, privately made, and lightweight aircraft, it manufactures composite and aluminum propellers. Ohio's Piqua is home to the company's headquarters.
Along with different propeller controllers, Hartzell also makes spinners, governors, ice protection systems, and other devices.

Answer: 3) Confounding variable
Explanation:Confounding variable is the variable that indicates about the external influential factors that produces the manipulated consequences of independent and dependent variable.This variable can lead to producing useless outcomes in an experiment.
According to the question, the changes occurring in interest of student in algebra can be due to the outside factors which are not generating the actual results and thus, experiment is getting ruined.
Other options are incorrect because application variable remain same for the experiment,system variable are the variables of certain system and reliability variables describe about the variable on which dependent or stable.Thus, the correct option is option(3)

Explanation:
Answer:
In Ivan Pavlov's famous studies, the food was the unconditioned stimulus, and the salivation was the unconditioned response.
Explanation:
Ivan Pavlov (1849-1936) was a Russian physiologist who conducted studies on behavior conditioning with dogs. In his studies, dogs would learn to associate different stimuli and produce certain responses.
A unconditioned stimulus is something that produces a natural, automatic response. That natural response is called unconditioned response. In Pavlov's studies with the dogs, he would show them food, and the dogs would start salivating because of it. That means the unconditioned stimulus was the food, and the unconditional response was the salivation.
The concept of social facilitation is so named because of the idea that when the presence of others is arousing, "this arousal facilitates a well-learned, dominant response".
<h3>What is
social facilitation?</h3>
The tendency for the presence of others to enhance a person's performance on a task is known as social facilitation.
Two types of social facilitation have also been defined: co-action effects and audience effects:
- A co-action effect: is when your performance on a task improves simply because there are other people performing the same job as you. As an illustration, consider working alongside coworkers in an office setting as opposed to by yourself.
- Audience effects: An audience effect is when your performance improves as a result of performing in front of a crowd. A pianist playing at home as opposed to performing in front of an audience is an example.
In addition, three more components are believed to play a role in social facilitation:
- physiological (drive and arousal),
- cognitive (distraction and attention), and
- affective (emotional) factors (anxiety and self-presentation).
