Resistance can be obtained by the following formula:
R = <span>ρ (L/A)
where:
R = resistance
</span>ρ = resistivity of copper (<span>1.68<span>x10^-8</span></span>)
L = Length = 3.1m
A = cross-sectional area = pi * (d/2)^2 = pi * (1.7mm)^2 = 2.269 mm^2
R = (1.68x10^-8) (3.1 / 0.0000022698)
R = 0.0229 <span>Ω</span>
Answer:
D, the lithosphere. (CRUST AND UPPER MANTLE)
Explanation:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Plate thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere (for example, the interior parts of North and South America).

Answer:
Length/time
Explanation:
As in the definition...Velocity is the rate of change of displacement...so hence
Velocity = Displacement/Time...where Displacement is length
Velocity = Length/Time
When an object is falling and reaches a constant velocity, the net force on the object is <em>zero</em> (it's not accelerating), and the weight of the object is equal to <em>the force of air resistance against the object</em>. (choice-D)
