Two electromagnets contain the same types of magnets
Ira Lisetskai [31]

Answer: The first electromagnet has a more powerful current than

the second

Explanation:

Since the two electromagnets contain the same types of magnets and wires. If the magnet In the first moves much faster than the second. Therefore:

The first electromagnet has a more powerful current than the second

Because the induced EMF is proportional to the induced current.

Where the induced EMF depends on the speed of the magnet according to the formula below

EMF = BVL

So, increase in speed of the magnet will cause more powerful induced current and emf

Which example is NOT a part of the electromagnetic spectrum?
Alekssandra [29.7K]

Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

<h2>Further Explanation </h2><h3>Electromagnetic waves  </h3>
  • Electromagnetic waves are types of waves that do not require a material medium for transmission.
  • These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
  • They include, light waves, radio waves, x-rays, infra-red, etc.
<h3>Electromagnetic spectrum </h3>
  • An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.  
  • Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
  • The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
  • The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
  • In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.
<h3>General characteristics of electromagnetic waves  </h3>
  • They travel with the speed of light (3.0 x 10^8 m/s)
  • They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
  • They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
  • They can travel through vacuum

Keywords: Electromagnetic spectrum, electromagnetic waves.

in baseball, a pitcher can accelerate 0.15kg ball from rest to 98 mi/hr in a distance of 1.7m. (a) What is the average force exe
Step2247 [10]

Answer:

F=84.68 N

Required force increases

Explanation:

By the equation

v^{2}=u^{2} +2as\\ 98^{2}*1609.344^{2}/(60*60)^{2}=0+2*a*1.7\\a = 98^{2}*1609.344^{2}/((60*60)^{2}*2*1.7)\\a = 564.50m/s^{2} \\

By newton's second law :

F=ma\\F=0.15*564.50  \\F=84.68 N

When the mass increased the force increases as the equation.

F=ma
