Answer:

Most responsible for the formation of a star is gravitational force.

Explanation:

A fundamental force that acts between any two bodies having mass is the gravitational force. Though it is a weak force but it plays the major role in formation of the universe.

The stars are born in molecular cloud of dust and gases - the nebula. This cloud condenses under its own gravity and contracts to form the core. Further, more mass is gathered as the core starts spinning due to gravity.

When the nuclear fusion starts, the balance between the pressure and gravity holds the star together.

Thus, most responsible for the formation of a star is gravitational force.

Most responsible in the formation of stars is the GRAVITATIONAL Force. The gravitation force is a force that brings mass to one another to form the stars. Isaac Newton make a law of gravity. Star formation is included in the branch of Astronomy.

The missing diagram is in the attachments.

Answer: X: positive Y: positive

Explanation: Electric field is a vector quantity, which means it can be represented by a vector arrow: the arrow points in the direction of electric field and its length represents the magnitude at a given location. There are another representation of the electric field called electric field lines, in which the line points away from a positively charged source and towards a negatively charged source. This occurs because it follows a pattern, where the lines points in the direction that a positive test charge would have if it is accelerating on the line.

Analyzing the diagram, it can be observed that the lines are pointing away from both of the charged objects. Therefore, both X and Y are positively charged.
