The sun is actually plasma but let us say that it is actually a Gas ball, as are all stars. All stars are essentially made out of gasses.
Answer:
(a) To draw water from a well we have to pull at the rope.
(b) A charged body attracts an uncharged body towards it.
(c) To move a loaded trolley we have to pull it.
(d) The north pole of a magnet repels the north pole of another magnet.

Just trust me
Answer:
Explanation:
The electric force between two point charges can be calculated by Coulomb's Law:
We have to calculate the distance between two points; (0,0) and (0.3 m, 0.2 m).
Now we can apply Coulomb's Law
The minus sign in front of the force means that the force is attractive.
The direction of the force can be calculated as follows:
where θ is the angle between F and the x-axis. This angle can be calculated by the triangle with edges 0.3 m, 0.2 m, and 0.36 m.
So, sin(θ) = 0.2/0.36 = 0.55 and cos(θ) = 0.3/0.36 = 0.83.
Finally,
The kinetic energy and potential energy are the two types of the mechanical energy. The generators are used to produce electricity, which is basically the electrical energy. Hence, the generators convert kinetic energy (mechanical energy) into the electrical energy which is supplied to our homes.
Hence, the correct answer is: Mechanical energy to the Electrical energy
The acceleration of the box is 6 m/s²; option A.
<h3>What is the acceleration of the box?</h3>
The acceleration of the box is determined as follows:
Frictional force = 660 * 0.15 = 99 N
Net force = 500 - 99 = 401 N
- Force = mass * acceleration
Mass of the box = 660/9.8 = 67.3 kg
Acceleration = net force/mass
Acceleration = 401/67.3
Acceleration = 6 m/s²
In conclusion, the acceleration of the box is determined from the net force and the mass of the box.
