A frame of reference can be thought of as the state of motion of the observer of some event. For example, if you're sitting on a lawn chair watching a train travel past you ... you could even watch a glass of water sitting on a table inside the train move ... This seems like a simple and obvious example, yet when you take a step

Which of the following is NOT considered electromagnetic radiation? x-rays radio waves cosmic rays ultraviolet light
OlgaM077 [116]

Answer:

Cosmic ray is not considered electromagnetic radiation.

Explanation:

Electromagnetic radiation refers to

  • It is Radiation that has both electric and magnetic fields and travels in waves.
  • Electromagnetic radiation can vary in strength from low energy to high energy.

X rays are the rays produced when a negatively charged electrode is heated by electricity and electrons are released, thereby producing energy. It is a type of radiation called EM waves.

Radio wave are wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. It is an EM wave.

Ultraviolet wave Invisible rays that are part of the energy that comes from the sun. It is an example of EM wave.

Cosmic ray is a high-speed particle either an atomic nucleus or an electron that travels through space.

Cosmic ray is not an electromagnetic wave.

Hence

Cosmic ray is not considered electromagnetic radiation

A roller coaster car travels through a loop in 3.1 s with a centripetal acceleration of 26 m/s^2. What is the radius of the roll
Ivanshal [37]

Answer:

The radius of the roller coaster loop is 6.3 m.

Explanation:

It is given that,  

Time taken by roller coaster, t = 3.1 s

Centripetal acceleration, a_c=26\ m/s^2

Velocity in a circular path is given by :

v=\dfrac{2\pi r}{t}  

Centripetal acceleration, a_c=\dfrac{v^2}{r}

So, acceleration, a_c=\dfrac{4\pi^2r}{t^2}

r=\dfrac{a_ct^2}{4\pi^2}

r=\dfrac{26\times 3.1^2}{4\pi^2}

r =6.3 m

So, the correct option is (A) " r = 6.3 m". Hence, this is the required solution
