It would decrease, hope it helps
Answer:
forces , motions , friction
Explanation:
Answer with Explanation:
We are given that
Resistance of solenoid,R=4.3 ohm
Magnetic field,B=
Current,I=4.6 A
Diameter of wire,d=0.5 mm=
Radius of wire,r=

Radius of solenoid,r'=1 cm=

Resistivity of copper,
We know that

Where 
Using the formula


Number of turns of wire=
Number of turns of wire=
Hence, the number of turns of the solenoid,N=799
Magnetic field in solenoid,B=






Length of solenoid=12.5 cm
1m=100 cm
Answer:
I believe it might be point A since the question ask what will result in the ln a largest increase in potential energy
Explanation:
Work Done = Force x Distance Moved
Work Done = 25 x 15 = 375 Joules
