What kind of radiation is emitted in the following nuclear reaction

Physics
1 answer:
miv72 [106K]3 years ago
4 0

Beta emission is occurring in the given nuclear reaction.

Answer: Option B

<u>Explanation:</u>

In this equation, the reactant is the Thorium atom, which is reduced to palladium. As the atomic number get decreased by one, so an electron will be emitted. This process of emission of electrons by radiation or decaying the reactant nuclei to form a new product nuclei is termed as beta emission.

So, the electrons are generally termed as beta particles while the positrons are termed as positive beta particles. So this is a kind of radioactive reactions where the reactant changes to new element by releasing an electron and thus there is a change in the atomic number of the product by one.

If the magnitude of the magnetic force on a proton is F when it is moving at 14.0 o with respect to the field, what is the magni
sergeinik [125]

Answer:

The magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F

Explanation:

Given;

magnitude of the magnetic force is F at 14.0⁰ with respect to the field.

To determine the magnitude of the magnetic force at 32.5⁰ to the field, we apply the following formula and solve with proportion;

f*Sin(14.0⁰) = F

f*Sin(32.5⁰) = ?

= \frac{f*Sin(32.5^o)}{f*Sin(14.0^o)}.F\\\\ =2.22 \ F

Therefore, the magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F

Which two statements describe what happens in both nuclear fusion and nuclear fission reactions?
Darina [25.2K]

Answer:

.

Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy.

nuclear fission reactors include the possibility of radiation-releasing nuclear accidents, the problems of radioactive waste disposal, and the possibility of contributing to nuclear weapon proliferation

Some volcanic eruptions are quiet and others are violent what causes this difference?
Step2247 [10]
Volcanoes that produce explosive eruptions tend to have thicker, more viscous magma, and a greater volume of gas. <span>Different types of volcanoes tend to produce different types of eruptions. Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The main difference is the shape of the volcano.

Calculate the mass of an object that is accelerating 14 m/s^2 with a force of 280 N
Masteriza [31]

Answer:

\boxed {\boxed {\sf 20 \ kilograms }}

Explanation:

Force is the product of mass and acceleration.

F=m*a

We can find mass, since we know the acceleration and force.

The acceleration is 14 meters per square second. The force is 280 Newtons, but we should convert the units to make the problem simpler later on.

  • 1 kilogram meter per square second is equal to 1 Newton.
  • 280 Newtons are equal to 280 kg*m/s²

F= 280 \ kg*m/s^2 \\a= 14 \ m/s^2

Substitute the values into the formula.

280 \ kg*m/s^2 = m* 14 \ m/s^2

We want to solve for the mass or m. Therefore we must isolate the variable on one side of the equation.

m is being multiplied by 14 m/s². The inverse of multiplication is division. Divide both sides of the equation by 14 m/s²

\frac{280 \ kg*m/s^2}{14 \ m/s^2}=\frac{m*14 \ m/s^2}{14 \ m/s^2}

\frac{280 \ kg*m/s^2}{14 \ m/s^2}=m

The m/s² will cancel, which is why we converted the units earlier.

\frac{280 \ kg}{14 }=m

20 \ kg=m

The mass of the object is <u>20 kilograms.</u>
