Computer simulation is useful because it helps in the prediction of what will likely happen in the future using data from past events.
<h3>What is computer simulation?</h3>
- This is the use of computer models to represents a hypothetical scenarios that are likely to be obtained in the real world.
Computer simulations are useful in studying phenomena in the universe because they help us to achieve the followings;
- It helps in the prediction of what will likely happen in the future using data from past events.
- It saves cost and time of carrying out actual experiments.
- It can help prevent a disaster that may occur in the future.

Answer:
D. two positively charged objects
Gravity is the only one, since there's no air resistance.
Answer:
Mass of natural gas needed to heat the room is 350,000BTUs
Explanation:
The heating efficiency of a furnace is never 100% because not all energy is released and not all heat is available to heat the place. A lesser efficiency requires more consumption of fuel. Heating values are used for heating fuels in order to calculate the mass of fuel needed.
The heating value of natural gas is 1,000,000BTUs
Therefore the formular for calculating mass of natural gas needed= Heating value of natural gas×efficiency.
Mass=1,000,000×0.35
Mass=350,000BTUs
