Answer the assignment questions using the World Geology map in this lesson and/or the earth's lithospheric plates map in the ass

ignment document. You can also do an Internet keyword search for U.S. Geological Survey Plates of the Earth Map to find some really good images that can be used as a reference for this assignment.
1. Wegener formed the theory of continental drift in 1912. What prevented research of the ocean floor, paleomagnetism, and earthquakes at that time?

2. If many different observations can all be explained by the same theory, does that make the theory true? Does it make the theory more likely? Explain your answer.

3. What evidence is there to suggest that the Earth is composed of tectonic plates?

4. What evidence is there to suggest that tectonic plates move?

5. Select Topography and Major Plates on the World Geology map. Describe the topography at the boundaries between the following pairs of plates: South American and Nazca, Indian and Eurasian, and Pacific and North American.

6. Observe the border between the Indian plate and the Somali plate. Do you see the same landforms as at the boundary between the Indian plate and the Eurasian plate? Explain.

7. Select Earthquakes and Major Plates on the World Geology map and observe earthquake activity around the South American plate. Based on your observations, what can you conclude about lithospheric motion of the South American plate with the Nazca plate and the African plate? Explain your answer.

8. How certain do you feel that the theory of plate tectonics is correct? What evidence would you use to support your opinion?

A diver makes 1.0 revolutions on the way from a 9.2-m-high platform to the water. Assuming zero initial vertical velocity, find
____ [38]

Answer:

Average angular velocity ≈ 4.59 rad/s

Explanation:

Using the equation of motion,

H = ut + (1/2)t² ............................ equation 1.

Where H= height, u = initial velocity(m/s), g = acceleration due to gravity(m/s²), t = time(s)  u= 0 ∴ ut =0

H =(1/2)gt².................................... equation 2.

making t² the subject of the relation in equation 2,

∴ t² = 2H/g

Where H = 9.2 m, g= 9.8 m/s

∴ t² = ( 2×9.2)/9.8

t = √(2 × 9.2/9.8) = √(18.4/9.8)

 t = 1.37 s.

The average angular velocity = θ/t

Where θ = is the number of revolution that the diver makes, t  = time

           θ = 1 rev.

Since 1 rev = 2π (rad)

           t = 1.37 s

 Average angular velocity = 2π/t

π = 3.143

 Average angular velocity = (2×3.143)/1.37 = 6.286/1.37

   Average angular velocity ≈ 4.59 rad/s

What equation gives the position at a specific time for an object with constant acceleration? 
malfutka [58]
Given constant acceleration, we can get the final position of an object in terms of both its initial velocity and its acceleration using one of the equations of motion.

The equation that we will use is:
Xf = Xi +  Vi*t + (1/2)*a*t^2
where:
Xf is the final position of the object
Xi is the initial position of the object
Vi is the initial velocity of the object
t is the time
a is the constant given acceleration

While playing her guitar , karen plucks one string with increasing levels of force. What effect does this have on the sound prod
Lena [83]

Answer:

The amplitude of vibration of string will increase due to which loudness of sound will increase

Explanation:

As we know that the guitar is based on the principle of Resonance. When string of the guitar vibrates at a given frequency then the sound produced in the hollow part of the guitar will also be at same frequency.

This is known as resonance condition, so guitar will produce same frequency sound as that of frequency of string.

Now if the string is plucked with increasing level of force then it will increase the amplitude of vibrations of the string due to which the sound produced in the guitar will also be of same level.

So here we can say that amplitude and intensity of sound related as

I = kA^2

so on increasing amplitude the intensity will increase and hence it will produce loud sound
