The work that the man does is the scalar product of the force applied by the man and the horizontal displacement of the bag.
<h3>What is the work done?</h3>
In Physics, we define the work done as the product of the of force and distance. Hence, we generally define the work done as that which occurs when the force applied moves a distance in the direction of the force. This implies that the work done is not a vector but a scalar quantity.
In relation to the man and the bag, the work done is the product of the force that the man applies and the displacement of the bag. As such, the reason for the tiredness of the man is that the internal energy that he possesses is transferred to moving the bag.
Thus, the work that the man does is the scalar product of the force applied by the man and the horizontal displacement of the bag.

Copernicus started a scientific revolution with his theory that, D the Earth revolved around the sun.
Answer:
A. Both exceed the matter-energy equivalent of luminous matter.
B. Dark matter has only an attractive gravitational effect, while dark energy is repulsive.
Explanation:
Dark matter and dark energy together constitute about ninety-five percent of the of total matter-energy equivalence in the universe. So, they exceed the matter-energy equivalent of luminous matter.
Dark energy is the repulsive force that is accelerating the expansion of the universe. Dark matter only has an attractive gravitational effect but does not interact with light of any kind.
The answer is 4,000 because there are 1 million watts per mega wat so 24x1,000,000 = 24,000,000 / 6,000= 4,000
