Answer:

2. The star is a member of binary eclipsing star system.

Explanation:

The question above shows an example of an eclipsing binary star. This type of star is very variable because the intensity of its brightness varies in the deccore of a few hours. This is because these stars are so close to an observer's field of view on the Earth's surface that they are easily eclipsed, and it is exactly these eclipses that cause the brightness of these stars to vary, which undergo a constant period of approximately 73 hours. intense shine, followed by constant drops in the intensity of that shine (lasts about 2 hours).

Reward power involves the potential to influence others due to one's control over desired resources.
Anestetic [448]

The capacity to influence others as a result of one's control over desirable resources is known as reward power.

An official authority granted to a work supervisor to bestow prizes on subordinates is known as the "reward power." It is position power, which means that the basis of the power is built on the authority a leader has within a corporation.

Managers or supervisors who provide incentives for workers to perform better are an example of those with reward power. By rewarding team members who reach a predetermined sales goal, they could achieve this.

Power from rewards isn't the same as influence from within. It is a formal authority granted to supervisors, project managers, or team leaders who have formal authority. For any other reason but productivity at work, they do not give out prizes.
