Answer:

Fusion

Fission

Explanation:

The first problem describes a nuclear fusion process. In this process;

small atomic nuclei combines to form a larger one.
it is accompanied by a large release of energy
this energy provides the needed temperature to set up another light nuclei to fuse.

The second problem describes nuclear fission,

a heavy nuclide is bombarded with a neutron.
the product formed becomes unstable and subsequently breaks down.
This leads to a series of chain reactions until stability is attained.

Use the drop-down menu to answer the question. In the equation I = v over r , what does I stand for? please help

ExtremeBDS [4]

Answer:

Current

Explanation:

The equation you mentioned is also known as Ohm's law, which can be applied for any circuit containing a battery and one (or more) resistors:

$V=IR$

where

V is the voltage

I is the current

R is the resistance

We can re-arrange the equation and rewrite it explicitely for I, the current, to match the equation mentioned in the text of the question, and we have:

$I=\frac{V}{R}$

An unknown charged particle passes without deflection through crossed electric and magnetic fields of strengths 187,500 V/m and

Kobotan [32]

Answer:

Explanation:

Given that

The electric fields of strengths E = 187,500 V/m and

and The magnetic fields of strengths B = 0.1250 T

The diameter d is 25.05 cm which is converted to 0.2505m

The radius is (d/2)

= 0.2505m / 2 = 0.12525m

The given formula to find the magnetic force is $F_{ma}=BqV---(i)$

The given formula to find the electric force is $F_{el}=qE---(ii)$

The velocity of electric field and magnetic field is said to be perpendicular

Electric field is equal to magnectic field

Equate equation (i) and equation (ii)

$Bqv=qE\\\\v=\frac{E}{B}$

$v=\frac{187500}{0.125} \\\\v=15\times10^5m/s$

It is said that the particles moves in semi circle, so we are going to consider using centripetal force

$F_{ce}=\frac{mv^2}{r}---(iii)$

magnectic field is equal to centripetal force

Lets equate equation (i) and (iii)

$Bqr=\frac{mv^2}{r} \\\\\frac{q}{m}=\frac{v}{Br} \\\\\frac{q}{m} =\frac{15\times 10^5}{0.125\times0.12525} \\\\=\frac{15\times10^5}{0.015656} \\\\=95808383.23\\\\=958.1\times10^5C/kg$

Therefore, the particle's charge-to-mass ratio is $958.1\times10^5C/kg$

To identify the particle

Then 1/ 958.1 × 10⁵ C/kg

The charge to mass ratio is very close to that of a proton, which is about 1*10^8 C/kg

Therefore the particle is proton.
