Explanation:
biotic factors are the things which have life like animals and plants
And Abiotic factors are the things which don't have life like air,stone and river
Nuclear fusion and nuclear fission are two different types of energy-releasing reactions that occur in the nuclei of an atom.
Here are the major differences between the two:
1. To differentiate the two, fission is the splitting of an atom into two or more smaller atoms while fusion is the conjoining or fusion of two or smaller atoms into larger one.
2. Fission does not normally occur in nature while fusion occurs mostly in heavenly bodies such as the stars.
3.Fission produces highly radioactive particles that can be hazardous to both the living things and its habitat or environment while fusion is "clean energy" and "environmental friendly" meaning there are fewer radioactive particles are produced. But if a fission "trigger" is being used, there will be radioactive particles produced.
Among the two nuclear changes, fission is widely used because this reaction produces heat in nuclear reactor. This heat is used to generate steam which operates the turbines to eventually produce electricity.
Answer:
a. and b. both are correct. the number of electrons and neutrons IN THIS CASE of nitrogen Is same.
Imagine you are playing golf, and you’ve just set up the golf ball on the tee. You test your grip, take a few practice swings, and peer into the distance at the flag pole marking the first hole for the course. Your wise golf ball guru (who happens to also teach physics) tells you to “Be the ball, young grasshopper.” So you close your eyes and picture the distance the ball must travel. “Yes, young earthworm”, your sensei says, “that distance you see is the displacement you must achieve, displacement is the change in position from one place to another.”
You meditate on this nugget of wisdom, and you start to feel like you and the golf ball are one. But the hole still seems so far away: “How do I change the position of the ball, sensei?
Your sensei replies: “Ahh, the ball cannot simply teleport instantly, it requires velocity; you must change the position of the ball over time.”
In a brilliant burst of enlightenment, you know what you must do. The golf ball sits there minding its own business; with a velocity of 0, and it doesn’t have any plans on moving anytime soon until… WHACK! You hit that golf ball with your club and the ball goes flying through the air. Suddenly the ball is moving, and fast! You know you’ve made your sensei proud, the ball is being displaced, sailing from one position to another toward the hole, This change in position as time passes is what we call velocity.
