A ½-hp motor requires 120 volts. What amperage is required?
Zolol [24]

Answer:

  3.11 A

Explanation:

Use the given relations between power, horsepower, voltage, and current to find the current requirement for the motor.

  P = hp(745.7 W) = (1/2)(745.7 W) = 372.85 W

  I = P/V = (372.85 W)/(120 V) = 3.1071 A

The amperage required is about 3.11 A.

What ways are people and their communities impacted by wildfire?
skelet666 [1.2K]

Explanation:

Aren't these all correct? I mean all of these are possibilities, except for the first one and the 5th one. I'll explain them all :)

1) Destruction of wildlife habitat

This doesn't really affect people. Mainly the animals living in the wild, because their homes would get burnt down, or ruined so they need to find a new place to live.

2) Timber Industry Losses

Wildfires can lower job rates in the timber industry, which can leave people struggling, looking for a new job.

3) Transportation Shutdowns

For example, things like trains might not be able to work.

You know those large railroads that are getting held up? Those could get burnt down, or unstable, which could lead to many injuries and preventions to get somewhere.

4) Houses Burned or Damaged

This is probably one of the most well known issues of wildfire.

Because of this, a bunch of citizens might not be able to live anywhere if their home gets burned down. Some people are lucky and have family nearby they can live with, but others don't, forced to live on the streets.

5) Loss of Tourism

This issue really only effects specific people.

Only people who really have any sort of relationship with touring would feel threatened by these changes.

6) Health Problems from Breathing Smoke

Yes, this is a huge issue.

Inhaling harmful smoke can inflame your lungs and airway, causing them to swell and block oxygen. This can lead to acute respiratory distress syndrome and respiratory failure.

7) Loss of places of employment

Just like number 2, this could leave people stranded with nowhere to go. Some might have to become homeless if they can't pay rent, or buy groceries.

8) Town Buildings Burned or Damaged

Think about it-- How would you feel if your town building got burnt down? It would be a huge deal, and will take months; maybe years to rebuild.

I have no clue if I did this the way you wanted, but- here. xd
