What are the main differences between fission and fusion?​

Physics
1 answer:
inessss [21]3 years ago

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: ^{238}_{92}U\longrightarrow^{234}_{90}Th+^{4}_{2}\alpha

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.

Please help me do this problem
Digiron [165]

Answer:

i) acceleration from B to D is 0, because the velocity is constant (stays the same)

ii) whatever units of distathat might be, we can calculate the number:

for 4 time-steps (2 to 6) the velocity is 6 per time step, that makes 24 distance units in these 4 time steps. it's the same the area underneath the graph.

there is also the vertical line from 0 to 2. we can calculate that distance like the area of a triangle with 2*6 / 2 = 6

the total distance from 0 to D is therefore 30

A 9.0-cm-long spring is attached to the ceiling. when a 1.8 kg mass is hung from it, the spring stretches to a length of 18 cm .
Alex Ar [27]
The spring constant is computed by:
F = kx

Where: F is the force applied in newtons (N)

k is the spring constant measured in newtons per meter (N/m); and

x is the distance the spring is stretched (m)
and

F = mg

Where: F is the force pulling objects in the direction of the Earth.

m is the mass of the object.

g is the acceleration due to gravity; 
So plugging our values in the formula:

F = mg

 = (1.8) (9.81) = 17.658N 

k =

F/x = 17.658 /0.09 = 196.2 N/meter

In a nuclear power plant, the temperature of the water in the reactor is above 100°C because of what?
SVETLANKA909090 [29]

Answer:

The temperature of the water increases because the nuclear reactor heats it producing steam

Explanation:

The nuclear power plants are usually defined as those thermal plants where the nuclear reactors are used in order to generate heat that eventually leads to the rotating of the turbines and produces electricity. Here the nuclear reactor heats the water, and it increases above a temperature of 100°C, where this heat energy plays a key role in the entire process. It is an efficient method as it does not lead to the emission of any green house gases that are harmful to the environment.
