Answer:
4
Explanation:
It has 8 O atoms and 4 O2(g) molecules
The correct answer is:
Work is negative, the environment did work on the object, and the energy of the system decreases.
In fact, the work-energy theorem states that the work done by the system is equal to its variation of kinetic energy:
In this problem, the variation of kinetic energy 
is negative (because the final velocity is less than the initial velocity), so the work is negative, and this means that the environment did work on the object, and its energy decreased.
The correct answer is D) The closet point in the Moon's orbit to Earth
This does not refer to the Moon only. It refers to any satellite and to its closest point to Earth.
A Ignite. Because. When you put coal in a gas pit, it ignites and burns. However, there is a chance that all of us fed
Work done = force x distance
work done = 15 x 3
work done = 45J
