Abase is a substance that can a hydroxide ion. a) donate b) bond with c) accept

A base is a substance that can donate a hydroxide ion.

option A)donate is the right option.

Explanation:

bases are substances that, in watery arrangement, discharge hydroxide (OH−) particles, are dangerous to the touch, can taste severe if a soluble base, change the shade of markers (e.g., turn red litmus paper blue), respond with acids to shape salts, advance certain concoction responses (base catalysis),

coil wire, increase current, put iron inside the coil

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.
