Which pattern in electronegativity do elements in the periodic table display? A.) Electronegativity is lowest on the left and right sides of the periodic table, and highest in the middle of a row.
B.) Electronegativity is highest on the left and right sides of the periodic table, and lowest in the middle of a row.
C.) Electronegativity decreases from left to right within a row of the periodic table.
D.) Electronegativity increases from left to right within a row of the periodic table.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

the components of a vector are the parts of the vectors that are to each other.
