Answer:
The causes of continental drift are perfectly explained by the plate tectonic theory. plate tectonic explanation< Plate tectonics, theory dealing with the dynamics of Earth ’s outer shell—the lithosphere —that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes

Answer:
circumference of earth = 24000 miles
Explanation:
given data
New York and Los Angeles distance = 3000 mi
time difference = 3 h
to find out
circumference of the Earth
solution
we find speed first that is
speed = 
speed = 
speed = 1000 mph
now we know speed of earth is
speed = 
so
circumference = speed × time of rotation
and we know earth take 24 hours to rotate at its axis
so
circumference of earth = 1000 × 24
circumference of earth = 24000 miles

Answer:
<u>b. 2.27 N</u>
Explanation:
Fe = (k)(Q1)(Q2) / d²
k ≈ 9 × 10⁹ N m² / C² [Coulomb's Constant] or 8.98 × 10⁹ (nearest hundredth).
q = particle charge [Coulombs; C]
d = distance [Meters; m]
Fe = Electrostatic force [Newtons; N]
________________________________
Fe = (9×10⁹)(3.5 × 10^(-8)(-4.5 × 10^(-6))/(.25)² N =
(9)(3.5)(-4.5) × (10^(9))(10^(-8))(10^(-6) / (.25)² N =
(9)(3.5)(-4.5) × (10^(9 - 8 - 6)) / (.25)² N =
(-141.75) × 10^(-5) / (.0625) N =
141.75 × 10^(-5) / (.0625) N
[opposite direction] =
(1.4175 × 10^(2)) × 10^(-5) / (.0625) N
[opposite direction] =
1.4175 × 10^(-3) / .0625 N
[opposite direction] =
1.4175 × 10^(-3) / 6.25 × 10^(-2) N =
14.175 / 6.25 N [opposite direction] =
2.268 N ≈ 2.27 N [opposite direction].
The answer they are looking for is the last one. However the last two are technically correct but the third one would result in negative work.
