Answer:
20.35m per minute
Or
1,221.43 per hour
100/5=20
200/7= 28.57
50/4= 12.5
20+28.57+12.5= 61.07
61.07/3= 20.35m per minute
Or
20.35 x 60= 1,221.43m per hour
Conductor answer is conductor I’m sure
Answer:
<em>Fission</em> means breaking.
The process of combining two small nuclei is called <em>fusion</em>.
Explanation:
The process of breaking a heavy nuclei to form two or more lighter nuclei is called <em>Fission</em>.
The heavy nuclei ,like Uranium, are bombarded with slow moving electrons, which are known as thermal electrons. On bombarding, the nuclei disintegrates to form two or more smaller nuclei releasing a huge amount of energy in the process. Fusion is a exothermic process.
The process of fusion is used in nuclear reactors.
Example:
The process of combining two lighter nuclei to form a heavier nuclues is called Fusion.
Energy is released or absorbed during the process.
Fusion takes place in the sun.
Answer:
Dear user,
Answer to your query is provided below
Acceleration is zero because of no change in velocity.
Explanation:
Remember that velocity is a vector quantity and a vector can change in 3 ways
•Magnitude only
•Direction only
•Both magnitude and direction.
Now the magnitude of velocity (speed) can stay constant while the direction is changing. This is the case in circular motion.
In the question above, it is mentioned that the girl is moving along a straight road. Therefore no change in direction of velocity.
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
EXAMPLE: A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. A stretched elastic string in a longbow.
