This assertion is accurate; electromagnetic signals are effectively blocked from entering the cable and causing noise by the braided metal shield.

<h3>What is electromagnetic ?</h3>

The study of charge, its forces, and the fields that surround it is known as electromagnetic. Two components of the electromagnetic electric field are electricity and magnetism. In science, electromagnetism is just an interaction that takes place between charged particles. It is also the dominant force in interactions between atoms and molecules and is also the second-strongest of a four basic interaction, after the strong force.

<h3>How does electromagnetic work and what was its purpose?</h3>

Electromagnets are wire coils with electricity flowing through them. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.

Consequently, electromagnetic governs much more than only electricity and magnetism. It is the force that holds oppositely charged electrons to oppositely charged atomic nuclei, allowing for the formation of stable atoms and the occurrence of chemistry, including the chemistry that gives rise to life.

A piston motion moves a 25-kg hammerhead vertically down 1 m from rest to a velocity of 50 m/s in a stamping machine. What is th

Alja [10]

Answer:

31.005 KJ

Explanation:

We are given that

Mass of hammerhead=25 kg

Initial velocity,u=0

Final velocity,v=50 m/s

h=-1 m

h'=0

We have to find the change in total energy of the hammerhead.

Change in total energy= $E_2-E_1=m(u_2-u_1)+\frac{1}{2}m(v^2-u^2)+mg(h-h')$

Using the formula

Change in internal energy of hammerhead= $m(u_2-u_1)=0$

Change in total energy= $\frac{1}{2}(25)(50)^2+25\times 9.8(-1)$

Where $g=9.8m/s^2$

Change in total energy= $31005 J=\frac{31005}{1000}=31.005 KJ$

1 KJ=1000 J

Discuss the relationship between electric and magnetic fields. How are they related?

<span>Discuss the relationship between electric and magnetic fields. How are they related?</span>

The magnetic field is related to the electric field in such a way that magnetic fields moves perpendicular the electric field. This relationship exists between a magnetic field and an electric field is a consequence of associating elementary particles.

Which of the following is a characteristic of electromagnetic waves? (2 points)

muminat

Answer:

c They can only travel without a medium.

Explanation:

Electromagnetic waves are made up of electric field and magnetic field.

Here electric field will induce magnetic field and magnetic field will induce electric field.

So this type of field do not require any medium and in vacuum or air the speed of electromagnetic waves are same as speed of light

$c = 3 \times 10^8 m/s$

also we have different range of electromagnetic waves out of which a small range of electromagnetic waves is of visible region in which these waves are visible to us.

so correct answer is

c They can only travel without a medium.

A rock is dropped from a tall building. You can ignore air resistance. Determine its final speed and distance traveled after 4 s

Hunter-Best [27]

Answer:

Explanation:

According to Newton law of motion for a falling body:

v = u + gt

Where v is the final velocity, u is the initial velocity, t is the time taken to fall and g is the acceleration due to gravity.

Given that: t = 4 s, g = 10 m/s², u = 0 m/s(at top of building). Therefore substituting values:

v = 0 + 10(4)

v = 40 m/s

To find the distance h, we use the formula:

v² = u² + 2gh

Substituting values:

40² = 0² + 2(10)h

20h = 40² - 0²

20h = 1600

h = 1600 / 20

h = 80 m

The speed = 40 m/s, distance = 80 m
