Answer:

<h2>The temperature does not affect the strength of a magnet</h2>

Explanation:

An electromagnet is obtained by winding an insulated wire round a soft iron rod with the wire ends connected to a DC source. such magnets have temporary magnetic properties which disappears with time as the current supply is cut off.

Furthermore the strength off an electromagnet

  1. increases as current increases
  2. increases as the number of turns increases
  3. the type of magnetic core is highly essential as an iron core will do batter than a silver core

An advantage of electron microscopes compared to light microscopes is that electron microscopes are inexpensive and commonly use
Aleks04 [339]

The statement ‘An advantage of electron microscopes compared to light microscopes is that electron microscopes are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes do not have higher resolution that allows you to view smaller specimens allow you to view the true colors of the specimens being viewed’ is true. In fact, electron microscope is more efficient than a light microscope due to its mechanism using only light without magnifying the specimen a thousand times.

Help, I’m stuck. Will give Brainly + 22 pts up for grabs !

Answer:

let the speed of Allegra be x mph, then speed of Elliana is x+4 mph,

time to cover distance for Eliana is 2 hours, time to cover distance for Allegrais 2.5 hours,

since they both cover the same distance you have this,

distance (of Eliana) = distance (of Allegrais ),

distance=speed x time, so we have

speed (of Eliana) x time (of Eliana) = speed (of Allegra) x time (of Allegra),

2(x+4)=2.5x,

solve for x, then substitute back for speeds for Eliana and Allegra,

Eliana's speed = 16 + 4 = 20.

Allegra's speed = 16

A 2 kg book is sitting on a table. A 10 N force is pulling it to the right. A 3 N force is pulling to the left. What is the Net
ella [17]

Here's the 'vector equation' for that situation:

                  (10N right)  +  (3N left)

               = (10N right)  +  (-3N right)

               =     7N right .
