Answer: True

Explanation: Electromagnetic radiation travels in the form of waves, and while it can travel in a medium, electromagnetic waves actually do not need a medium to travel.

And one of the principles in the physics is that all electromagnetic waves travel at the speed of light, c, in a vacuum, so all electromagnetic waves travel at the same speed in a vacuum (not in materials, different waves can travel at different speeds in some materials), so this is true.

agasfer [191]

Answer: 168.75 N

Explanation:

first, let's convert microcoulombs to coulombs

q1 = 1e-4 C

q2 = 3e-5 C

r = 0.4 m

then use the equation Fe = \frac{kq_{1} q_{2}}{r^{2} }

plug in values --> F = (9e9*1e-4*3e-5)/(0.4)^2

F = 168.75 N

As a therapist who specializes in dreams, I would interpret Justina’s dream by using: 17. Freud’s wish-fulfilling theory.

<h3>Who is Sigmund Freud?</h3>

Sigmund Freud was an Austrian physiologist, neurologist, medical doctor and the founder of psychoanalysis. Also, Freud was born in Moravia on the 6th of May, 1856 and he was famously known around the world for his works on psychoanalytic theory of personality development.

In 1923, Sigmund Freud developed the personality theory through which he strongly argued that a person’s personality (human psyche) is structured into three (3) key parts and these include:

  • The Id (instincts).
  • Ego (reality).
  • Superego (morality).

According to Sigmund Freud, wish fulfillment simply means the satisfaction of a human desire through an involuntary thought process such as dreams. Thus, it typically happens to a person when unconscious desires are adequately repressed by both the ego and superego.

Which line could be added to show the difference a digita leader can make?
tia_tia [17]

Question: I was honored to be a part of an online group of students from the United States, Africa, and China seeking solutions to water shortages. While we all had great enthusiasm about changing the world, the project quickly dissolved because no one was willing to listen to differing viewpoints.

Which line could be added to show the difference a digital leader can make?

Answer:

The line that can be added to show the difference a digital leader can make is, "We saved the project by allowing each group to share their thoughts and then chose the best solutions"

Explanation:

A digital leader is the one who is innovative, creative, collaborative, experimental, curious and also able to network. The person should have forward thinking capability, most importantly should remain very adaptive, so that can remain relevant to the change. To archive this, he alone can do this. Must have different group of people through which could extract different ideas and views from which he/she could chose the right one for the desired situation.
