Since carbon has 4 valence electrons, a total of 4 bonds will be drawn withing methane, one between each H and the center C
Hope this helps
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
