Answer:
a. Bradon was flying at the speed rate of 350 miles/hour.
b. His velocity is 350 miles/hour due west.
Explanation:
The speed of an object is the ratio of distance moved to the time taken, while velocity is the ratio of displacement to time taken. The major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
Vector quantities are described by both magnitude and direction, while scalar have only magnitude.
From the question,
distance = 700 miles and time taken = 2 hours
a. speed = 
= 
= 350 miles/hour
∴ Bradon was flying at the speed rate of 350 miles/hour.
b. velocity = 
displacement = 700 miles of west, time taken = 2 hours
velocity =
= 350 miles/hour due west
His velocity is 350 miles/hour due west.
Answer:
1. One atom splits
2. large
3. neutrons
Explanation:
In the process of nuclear fission,1__one atom splits___.Fission only happens to very 2(__large___) atoms.The Fission process usually also produces several free 3(__neutrons___).
Nuclear fission is a radioactive decay process in which heavy and unstable radioactive nucleus decays into lighter ones with the release of energy and free neutrons.
Fission differs from fusion in that in nuclear fusion, two light atoms comes together to form a large one. This process releases a very great amount of energy.
The answer would be Oxygen. Hope this helps!
Answer: In factories they burn coal under a giant container(a really big gumbo pot pretty much). when the fire is hot enough it starts to boil. When it boils it creates steam and the steam blows on a fan that makes electricity.
