When the core of a star like the sun uses up its supply of hydrogen for fusion, the core begins to contract in size. The gravitational forces becomes strong and cause the star to reduce in size. as the star contracts, the temperature of the star also rises since the heat is distributed inside smaller Volume now.
This is a true fact.
Example: An object sitting still in place has energy called potential energy so if an object moving, kinetic energy, and pushes the other object not moving, then the potential energy object will now have kinetic energy; Change.
So, that IS a true fact.
I hope this helped!
The person's velocity relative to the shore is determined as 6.5 m/s.
<h3>
Velocity of the person</h3>
The velocity of the person is calculated as follows;
V(p/f) = V(p) - V(f)
where;
- V(p/f) is the velocity of the person relative to the ferry
- V(p) is the velocity of the person
- V(f) is velocity of the ferry
1.5 = V(p) - 5
V(p) = 6.5 m/s
Thus, the person's velocity relative to the shore is determined as 6.5 m/s.

<h3>Answer:</h3><h3>B.one coulomb</h3>
<h3>Explanation:</h3><h3>It takes an enormous number of electrons to equal one coulomb.In fact,it takes about 6.2x10¹⁸.Looking at this from the opposite perspective,one electron has a negative charge equal to -1.6x10¹⁹ coulombs.</h3>
Answer Balanced force // Force and Motion Equal forces acting in opposite directions are called balanced forces
