Answer:

D. The primary source, because it was written by the researcher

Explanation:

One should learn to trust the primary source more because it is the real work of the researcher.

A primary work defines the work of research from his or her experimental findings.

  • The primary source presents experimental data and other subordinates ones to reach a conclusion as seen from the view of the researcher.
  • A secondary source implies someone else documenting their own opinion about the primary experimental set up.
  • This can get dicey in the sense that results can be twisted to serve other ulterior motives.

When light passes into a lower index medium it will be deviated away from the normal. True or false
V125BC [204]

Answer:

\huge\underline\color{purple}{Answer ☘}

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density).

<h3><em>when </em><em>a </em><em>light </em><em>ray </em><em>goes </em><em>from </em><em>a </em><em>medium </em><em>with </em><em>higher </em><em>refractive </em><em>index </em><em>to </em><em>a </em><em>medium </em><em>with </em><em>lower </em><em>refractive </em><em>index.</em><em>.</em><em> </em><em>it </em><em>gets </em><em>deviated </em><em>from </em><em>the </em><em>normal.</em></h3>

<h2><em>hence.</em><em>.</em><em>.</em><em> </em><em>the </em><em>statement</em><em> </em><em>is </em><em>true.</em><em>.</em><em>.</em></h2>

A 2kg 2 kg object is moving in along the x x -axis under a single conservative force. When the object is at position x=0 x = 0 ,
Luden [163]

Answer:

The particle comes to rest before reaching the position x=4m.

Explanation:

When the object is at x=0m, all of its energy is kinetic energy. Using the equation for kinetic energy yields KE=1/2mv^2=(12)(2)(3)^2=9J. Using the given equation for potential energy when the object is at x=4m yields U=4x^2=4(4)^2=64J. Since the system only has 9J of energy, the object comes to rest before reaching x=4m.

PLEASE HELP (100)
morpeh [17]

Answer:

The work done will be W=55.27\: J

Explanation:

The work equation is given by:

W=F\cdot x

Where:

F is the force due to gravity (weight = mg)

x is the length of the ramp (3 m)

Now, the force acting here is the component of weight in the ramp direction, so it will be:

F_{x-direction}=mgsin(28)

Therefore, the work done will be:

W=mgsin(28)*3

W=4*9.81*sin(28)*3

W=55.27\: J

I hope it helps you!
