(2m west) + (3m south) + (4m east) + (1m north) =
[ (2m west)+(4m east) ] + [ (3m south)+(1m north) ] =
[ (-2m east)+(4m east) ] + [ (3m south)-(1m south) ] =
(2m east) + (2m south)
Now, so far, we have the orthogonal (perpendicular) components of the displacement ... the North/South component and the East/West component.
To combine these, it's time for Pythagoras:
Displacement = √[ (2m)² + (2m)² ]
Displacement = √ (4m² + 4m²)
Diplacement = √8m²
<em>Displacement = 2.83 meters Southeast</em>
Answer:sofa
Explanation:the weight of the mass of that object can be heavy (er) than the rest
<span>If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving a distinct North and South pole.

I don't understand the question
Explanation:
Please give it clearly
<h3><u>Answer;</u></h3>
= 480 Joules
<h3><u>Explanation;</u></h3>
We use the formula, Q - W = ΔU
Where, Q = Heat transferred to the system
W = Work done by the system
ΔU = Change of internal energy.
As per the question, Q = 658 J
ΔU = 178 J
Thus, W = Q - ΔU = (658 - 178) J = 480 J.
The energy used to do work by the system is 480 J.
