Wavelength = (speed)/(frequency) = 300,000,000/120,000,000 = 2.5 meters
Answer:
Explained
Explanation:
Given:
Ship travels due east from the Bar Harbor 38 miles before turning north
Yes it possible to calculate the exact direction of the ship by assuming there are no large islands in the way, and that the isolated ship does not cut off very far, then what we have here is a right triangle with a 72-mile as hypotenuse and a 38-mile as "adjacent" side. If θ is the angle out of Bar Harbor, we can write
, and θ = 58.14457°, or 58° 8' 40" north of east. That will be the exact direction.
Sedimentary rocks become metamorphic in the rock cycle when they are subjected to heat and pressure from burial. The high temperatures are produced when the Earth's tectonic plates move around, producing heat. And when they collide, they build mountains and metamorphose.
Igneous rocks form as magma cools below ground or lava cools on the surface. Sedimentary rocks are made from the eroded particles of other rocks or from mineral deposits left when water evaporates. Metamorphic rocks form when any existing rock undergoes intense and prolonged exposure to heat and pressure.
The one fact that needs to be mentioned but isn't given anywhere on or around the graph is: The distance, on the vertical axis, is the distance FROM home. So any point on the graph where the distance is zero ... the point is in the x-axis ... is a point AT home.
Segment D ...
Walking AWAY from home; distance increases as time increases.
Segment B ...
Not walking; distance doesn't change as time increases.
Segment C ...
Walking away from home, but slower than before; distance increases as time increases, but not as fast. Slope is less than segment-D.
Segment A ...
Going home; distance is DEcreasing as time increases. Walking pretty fast ... the slope of the line is steep.
Answer:
No
Explanation:
Recall that the hierarchy of wavelength color from minimum wavelength to maximum wavelength is:
and
As a result, blue light has a higher energy level than green and red light.
As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.
