Answer: 20 kgm/s
Explanation:
Given that M1 = M2 = 10kg
V1 = 5 m/s , V2 = 3 m/s
Since momentum is a vector quantity, the direction of the two object will be taken into consideration.
The magnitude of their combined
momentum before the crash will be:
M1V1 - M2V2
Substitute all the parameters into the formula
10 × 5 - 10 × 3
50 - 30
20 kgm/s
Therefore, the magnitude of their combined momentum before the crash will be 20 kgm/s
A. very small objects behave like like particles.
Answer:
The atomic number 26(iron) is the threshold value below which the fusion might occur.
Explanation:
Nuclear fusion is a reaction in which two or more nuclei are combined to form one or more different atomic nuclei and subatomic particles.
Energy released in a fusion reaction is because of a key feature of nuclear matter called the binding energy which is a measure of the efficiency with which its constituent nucleons are bound together.
As we go up in atomic number, the energy released per nuclei goes down until it hits a minimum which is for atomic number 26 (iron) and fusion is not possible.
According to the research, the correct option is a. The heat generated from the fission reaction is used to boil water, which rises and spins a turbine.
<h3>How is fision used to produce electricity?</h3>
In fusion, two atoms come together to form a larger one, releasing enormous amounts of energy in the process, this is used by generators to produce electricity.
As a result of nuclear fusion, large amounts of heat are generated that are used to produce pressurized steam, which allows mechanical energy to be obtained to start up electric power generators.
Therefore, we can conclude that according to the research, the correct option is a. The heat generated from the fission reaction is used to boil water, which rises and spins a turbine.
