Answer:
a. It creates a pattern of alternating rock stripes on both sides of a mid-ocean ridge.
Explanation:
Seafloor spreading is the theory that the oceanic lithospheric plates are in constant motion just as continental drift occurs.
When oceanic plates collide, the denser subducts under the less dense one, causing a destruction of oceanic lithosphere.
However, during seafloor spreading, a rift in the ocean can spill out some of the partially melted subducted rock. When the magma cools, there is an alternation in the magnetic variation of rocks formed by the series of volcanic action that has occurred underwater.
The variation shows younger rocks closer to the mid-oceanic ridge formed in the process. This variation is measured and compared to confirm that sea floor spreading has actually occurred.
Answer:
The minimum number of 100 Ω resistors that i need to design an effective resistor with 275Ω resistance are 8 resistors.
Explanation:
(2 Resistors of 100Ω in parallel) in <u>series with</u> (4 resistors of 100Ω in parallel) in <u>series</u> with 2 resistors of 100Ω.
2 resistors in parallel of 100Ω = 50Ω
+
4 resistors in parallel of 100Ω = 25Ω
+
2 resistors in series of 100 2Ω = 200Ω
=
275Ω
Answer:
A) 9000 Joules
B) 450 Watts
Explanation:
Work equals change in energy:
W = ΔPE
W = mgΔh
W = (600 N) (15 m)
W = 9000 J
Power is work per time:
P = W/t
P = (9000 J) / (20 s)
P = 450 W
pot energy depends on how high it is, kinetic on how fast it's going
if something falls, it gets lower and faster
Answer: The illusion of motion that occurs when a stationary object is first seen briefly in one location and, following a short interval, is seen in another location.
