What is a characteristic of nuclear fusion but not nuclear fission?

2 answers:

5 0

The answer is the energy of stars.

Fission is the type of nuclear energy simulated on earth, as it is the one used to generate electricity. Fusion, on the other hand, is much more complicated to achieve because it requires extremely hot temperatures compared to fission.

enyata [817]

Answer:

The maximum frequency of revolution is 3.6 Hz.

Explanation:

Given that,

Mass = 8 kg

Distance = 400 mm

Tension = 800 N

We need to calculate the velocity

Using centripetal force

$F=\dfrac{mv^2}{r}$

Where, F= tension

m = mass

v= velocity

r = radius of circle

Put the value into the formula

$800=\dfrac{8\times v^2}{200\times10^{-3}}$

$v^2=\sqrt{\dfrac{800\times200\times10^{-3}}{8}}$

$v=4.47\ m/s$

We need to calculate the maximum frequency of revolution

Using formula of frequency

$f=\dfrac{v}{2\pi r}$

Put the value into the formula

$f=\dfrac{4.47}{2\pi\times200\times10^{-3}}$

$f=3.6\ Hz$

Hence, The maximum frequency of revolution is 3.6 Hz.

Proper use of the friction zone makes it easier to:.

yulyashka [42]

Friction is the opposition offered to the movement of a surface on another and depends on the nature of the surfaces in contact.

<h3>What is friction?</h3>

The term friction refers to the opposition that is offered by surfaces in contact when they move over each other. The question is incomplete but I will try to help you the much I can.

Now recall that fricton only depends on the nature of the surfaces in contact. The friction is te reason when heat is provides in the moving parts of machines.

A person who weighs 509,45 N empties her lungs as much as

Masja [62]

Answer:

The weight of the girl = 1045.86 kg/m³

Explanation:

Density: This can be defined as the ratio of the mass of a body to the volume of that body. The S.I unit of density is kg/m³.

From Archimedes principle,

R.d = Density of the person/Density of water = Weight of the person in air/Upthrust.

⇒ D₁/D₂ = W/U............................... Equation 1.

Where D₁ = Density of the person, D₂ = Density of water, W = Weight of the person in air, U = Upthrust in water.

Making D₁ the subject of the equation,

D₁ = D₂(W/U)................................... Equation 2

<em>Given: D₂ = 1000 kg/m³ , W = 509.45 N, U = lost in weight = weight in air - weight in water = 509.45 - 22.34 = 487.11 N</em>

<em>Substituting these values into equation 2</em>

D₁ = 1000(509.45/487.11)

D₁ = 1045.86 kg/m³

Thus the weight of the girl = 1045.86 kg/m³
