The field of a solenoid is most like the field of a: long, straight wire single bar magnet horseshoe magnet single pole
2 answers:
Answer:
Single bar magnet
Explanation:
As we know that magnetic field of solenoid inside the solenoid is strong and given by formula
here we know
L = length of solenoid
i = current in the coil
now as we observe the field outside the solenoid the magnetic field will start decreasing as we go far away from the end.
so strength of magnetic field will be more near the end and start decreasing as we move away from it
this all characteristics are similar to the magnetic field of a bar magnet
so this solenoid is similar to a bar magnet
The outside magnetic field of a solenoid is similar to that of a bar magnet even though the inside field is strong and uniform.

The answer is A. Force is equal to mass x acceleration. The acceleration due to gravity is a constant so multiplying the mass by 2 would double the force.
Answer:
52.9 N, 364.7 N
Explanation:
First of all, we need to resolve both forces along the x- and y- direction. We have:
- Force A (178 N)
- Force B (259 N)
So the x- and y- component of the total force acting on the block are:
