Which of these statements best proves that electromagnetic forces are weaker than strong nuclear forces? Neutrons do not repel o

r attract each other when they are in the nucleus. Electrons do not move out of an atom when it forms bonds with other atoms. Protons do not move out of the nucleus of atoms although they repel each other. Atoms do not have any charge on them although they consist of charged particles.

Protons do not move out of the nucleus of atoms although they repel each other.

Remember that protons are particles with positive charge and they held together in the nucleus of the atom which is a tiny tiny region. As you know, like charges repel each other, which means that the protons exert a repulsion force.

Meteoric material dates the formation of the solar system at about_____ billion years.
Alja [10]

According to meteoric material, the solar system was formed around <u>4.6 billion years</u> ago.

<h3>What substance makes up a meteorite?</h3>
  • With just trace levels of sulphide and carbide minerals, they are primarily composed of iron-nickel metal.
  • Many asteroids melted during the radioactive element decay in the early solar system, and the iron they carried, being dense, sank to the centre to create a metallic core.
<h3>What is the term for meteorite metal?</h3>
  • Meteoric iron, also known as meteoritic iron, is a native metal and a protoplanetary-disk remnant from the early universe that is found in meteorites.
  • It is mostly composed of the metals iron and nickel, primarily in the crystalline phases kamacite and taenite.

If a spring constant of 128N/m is compressed by 0.18 m , how much potential energy is the spring?
Mademuasel [1]

Answer:

2.1J

Explanation:

Given parameters:

Spring constant  = 128N/m

Compression  = 0.18m

Unknown:

Potential energy of the spring  = ?

Solution

The potential energy of the spring is the elastic potential energy within the spring.

 To solve this;

   Elastic potential energy  = \frac{1}{2}  k e²  

k is the spring constant

e is the compression

 Now;

     Elastic potential energy  =  \frac{1}{2} x 128 x 0.18²  = 2.1J

An electromagnetic wave with a peak magnetic field component of 3.20 × 10−7 T carries what average power per unit area? (μ0 = 4π
IRISSAK [1]

Answer:

Explanation:

Average power per unit area =

I avg = c B₀² / 2μ₀

= 3 X 10⁸ X (3.2 X 10⁻⁷)² / 2 X 4π × 10⁻⁷

= 1.22 X 10
