should your directions to a friend for traveling from one city to another include displacements or distances?Explain

Answers

Answer 1
Answer: Displacements because it includes direction since you want to lead your friend to the right place. If you only include distances then it's like which way should they go. They don't know if it's north, east, south or west. They also don't know if they should travel in a straight line or do they have to make a lot of turns

What causes resistance in an electrical current

Answers

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.

cot θ ∙ sec θ = csc θ

Answers

To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ 
sec θ = 1 / cos θ
csc θ = 1 / sin θ

Using these identities:
cot θ ∙ sec θ = (cos θ / sin θ ) ( 1 / cos θ)

We can cancel out cos θ, leaving us with
cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc θ

You should vary your ____________ based on the size and noise level of the venue you are speaking in.

Answers

I think, the best word to fill the blank is "voice". You should vary your voice based on the size and noise level of the venue you are speaking in. Because when you are speaking you use your voice to be heard. Also, it is the only thing you can vary depending on the size and the noise when speaking in a certain location.
