A compass needle normally points toward Earth’s magnetic pole, which is near the North Pole. Which best explains why the needle

Mariana [72]

Answer:

Magnetism surrounding the wire draws the needle toward the wire.

Explanation:

Magnetism is a force which is responsible for the attraction and repulsion of objects. Magnetism is also generated around the wire in which current is flowing. This magnetism is stronger when more current flows through the wire. This magnetism is stronger than the magnetism of the poles so when the compass brought near to the electric wire, the needle moves toward the wire.

What can be determined from the frequency and wavelength of a wave?

sp2606 [1]

The frequency and wavelength of a wave allows you to determine the speed of a wave. Because the speed of a wave equals wavelength times frequency, you can determine speed knowing the both the frequency and wavelength.

Copper crystallizes in a face centered cubic lattice. if the edge of the unit cell is 351 pm what is the radius of the copper at

Troyanec [42]

Density of unit cell is mathematically expressed as
D = $\frac{\text{Z X Atomic Weight}}{\text{Avagadro's Number X a^3}}$

where, Z = number of atoms/unit cell = 4 (For FCC structure)
Atomic weight of Cu = 63.5 g
a = edge length = 351 pm = 351 X 10^-10 cm
Avagadro's number = 6.023 X 10^23

∴ Density of unit cell = $\frac{4X63.5}{6.023X10^2^3X(351X10^-^1^0)^3}$
= 9.752 g/cm3

Now, for FCC structure a = √8 r
where r = radius of Cu
∴ r = a/√8 = (351 X 10^-10)/√8 = 1.24 X 10^-8 cm = 124 pm
