What are the main differences between fission and fusion?​

Physics
1 answer:
inessss [21]3 years ago
4 0

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.

A certain superconducting magnet in the form of a solenoid of length 0.26 m can generate a magnetic field of 7.5 T in its core w
Mars2501 [29]

Answer:

Therefore

Number of turns in the solenoid is 19407.

Explanation:

Given:

Strength magnetic field at its center,

B = 7.5 T

length of solenoid = l = 0.26 m

Current, I = 80 A

To Find:

Turn = N = ?

Solution:

If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives

\int {B} \, ds= Bl=\mu_{0}NI

Therefore,

B =\dfrac{\mu_{0}NI}{l}

Where,  

B = Strength of magnetic field

l = Length of solenoid

N = Number of turns

I = Current

\mu_{0}=Permeability\ in\ free\ space=4\pi\times 10^{-7}\ Tm/A

N=\dfrac{Bl}{\mu_{0}I}

Substituting the values we get

N=\dfrac{7.5\times 0.26}{4\pi\times 10^{-7}\times 80}=19406.84=19407

Therefore

Number of turns in the solenoid is 19407.

A force of 1000 newtons was necessary to lift a rock. A total of 3000 joules of work was done. How far was the rock lifted?
zhenek [66]

Answer: 3 meters

Explanation:

If you were to use a 3 line answer then it would look like this:

d = W/F

d = 3000/1000

d = 3 meters

A 7.0-kg rock is subject to a variable force given by the equation f(x)=6.0n−(2.0n/m)x+(6.0n/m2)x2 if the rock initially is at r
stealth61 [152]
For Newton's second law, the force is equal to the product between the mass and the acceleration of the rocket:
F=ma
From which we can rewrite the acceleration as
a(x)= \frac{F}{m} =  \frac{1}{m} (6-2x+6x^2)
where m=7.0 kg.

The velocity of the rocket is the derivative of the acceleration:
v(x) =  \frac{1}{m} (-2+12 x)
and if we substitute x=9.0 m, we find the rocket velocity after 9.0 m:
v(9)= \frac{1}{7}(-2+12\cdot 9)=15.1 m/s
