b.
main
most dense
most expensive
only

Brass and bronze are both alloys(A) of copper because copper is the main(B) component in brass and bronze.

Explanation:

Brass and Bronze are used in our day to day life known as metal alloys.  Brass is an alloy of the metals like copper and zinc which has high percentage of metal copper with tin combined with it.  

Brass is dull yellow in color. Bronze is reddish brown in color. Brass was known to be present in 500 BC. Bronze was about 3500 BC known to be present.  Thus Bronze and Brass are both alloys of the metal copper since the main component in the brass and bronze is copper.

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

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.
