Laboratory Measurements Always Contain Some Error Depending On The Type Of Equip

Laboratory measurements always contain some error. Depending on the type of equipment used, that error can be quite substantial. One way to validate our density value from Part B is to do a completely different experiment to measure of the density of the block, then compare the two measurements

cube mass in air is 50.0 g

cube mass immersed in water is 5.6g

water temperature is 20 degree Celsius

density of water is .99821

previous calculation of density of the block immersed 40% was 1.16 g/cm^3

Laboratory Exercise For Plate Tectonicsearthquakes Related To A Hypothetical Pla

Laboratory Exercise for Plate Tectonics

Earthquakes Related to a Hypothetical Plate Boundary

Lesson Description

In this exercise we will plot 40 theoretical earthquake events at the juncture of two tectonic plates.  Students will then analyze the pattern of earthquake locations and compare these patterns to possible plate boundaries.

Learning Objectives

Student will learn to recognize the earthquake patterns associated with plate tectonic boundaries.

Step One

Plot the Earthquake Data found in Table #1 onto the Area Map (Figure #1). Feel free to duplicate this map to use as work copies. Place a dot or small circle on the map to represent each earthquake event (epicenter). Next to your earthquake location write the value of the depth at which that earthquake occurred (focus).

Step Two

Using the East-West Crossection (Figure #2) plot the surface location (epicenter) of each earthquake and then, based on the depth related to each earthquake event, plot the earthquake focus. On the crossection trace the top and bottom of the plate based on the earthquake focus depths.

Step Three

Answer the following questions.

Question #1: Does the pattern of deep and intermediate earthquakes indicate a tectonic plate boundary? If so, describe.

Question #2:Â  Is it possible to predict the thickness of this plate? How thick could this plate be? Does this thickness relate to a continental plate or oceanic plate? Oceanic plates are not 100 kilometers thick, discuss what then could account for the apparent thickness of this descending plate?

Question #3:Â  Can a second pattern be found that could be describing the other plate? Describe.

Lady Macbeth Act 1 Scene V Glamisthou Art And Cawdor And Shalt Be What Thou Art

Lady Macbeth (Act 1; Scene V):Glamisthou art, and Cawdor; and shalt be 

What thou art promised: yet do I fear thy nature; 

It is too full o’ the milk of human kindness 

To catch the nearest way: thou wouldst be great; 

Art not without ambition, but without 

The illness should attend it: what thou wouldst highly, 

That wouldst thou holily; wouldst not play false, 

And yet wouldst wrongly win: 

thou’ldst have, great Glamis, 

That which cries ‘Thus thou must do, if thou have it; 

And that which rather thou dost fear to do 

Than wishest should be undone.’ Hie thee hither, 

That I may pour my spirits in thine ear; 

And chastise with the valour of my tongue 

All that impedes thee from the golden round, 

Which fate and metaphysical aid doth seem 

To have thee crown’d withal.

Macbeth (Act 1; Scene VII):

He’s here in double trust; 

First, as I am his kinsman and his subject, 

Strong both against the deed; then, as his host, 

Who should against his murderer shut the door, 

Not bear the knife myself. Besides, this Duncan 

Hath borne his faculties so meek, hath been 

So clear in his great office, that his virtues 

Will plead like angels, trumpet-tongued, against 

The deep damnation of his taking-off; 

And pity, like a naked new-born babe, 

Striding the blast, or heaven’s cherubim, horsed 

Upon the sightless couriers of the air, 

Shall blow the horrid deed in every eye, 

That tears shall drown the wind. I have no spur 

To prick the sides of my intent, but only 

Vaulting ambition, which o’erleaps itself 

And falls on the other.

Use the excerpts from Macbeth to complete the following task:

Write an essay of at least three paragraphs, supporting the assertion that the character of Lady Macbeth is passionately ambitious while the character of Macbeth is more cautious. Be sure to include evidence from the text to support your answer. Remember to clearly state your main point and use correct citation in your response.
