A horizontal insulating rod of length 11.8-cm and charge 19 nC is in a plane with a long straight vertical uniform line charge.
SCORPION-xisa [38]

Answer:

11.962337 × 10^-4 N

Explanation:

Given the following :

Length L = 11.8

Charge = 29nC = 29 × 10^-9 C

Linear charge density λ = 1.4 × 10^-7 C/m

Radius (r) = 2cm = 2/100 = 0.02 m

Using the relation:

E = 2kλ/r ; F =qE

F = 2kλq/L × ∫dr/r

F = 2*k*q*λ/L × (In(0.02 + L) - In(0.02))

2*k*q*λ/L = [2 × (9 * 10^9) * (29 * 10^9) * (1.4 * 10^-7)]/ 0.118] = 6193.2203 × 10^(9 - 9 - 7) = 6193.2203 × 10^-7 = 6.1932203 × 10^-4

In(0.02 + 0.118) - In(0.02) = In(0.138) - In(0.02) = 1.9315214

Hence,

(6.1932203 × 10^-4) × 1.9315214 = 11.962337 × 10^-4 N

What characteristics of EM waves did you discover?
jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

  • There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values ​​at the same time and place.
  • The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
  • The shape of electromagnetic waves is transverse waves.
  • It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
  • The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
  • The universal constant of the velocity of electromagnetic waves in a vacuum is \boxed{ \ c = 3 \times 10^8 \ m/s. \ }
  • The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
  • Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.
<h3>Further explanation</h3>
  • Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
  • From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
  • Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
  • As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
  • Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
  • Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2
Basile [38]

Answer:

\boxed {\boxed {\sf 252.5 \ Newtons }}

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

F=m*a

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

  • m= 50.5 \ kg
  • a= 5.0 \ m/s^2

Substitute the values into the formula.

F= 50.5 \ kg * 5.0 \ m/s^2

Multiply.

F=252.5 \ kg*m/s^2

  • 1 kilogram meter per square second is equal to 1 Newton.
  • Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.

F= 252.5 \ N

The force required is <u>252.5 Newtons</u>.
