Question

Suppose you measure a square piece of carpet to have an edge of length of 10.5 in. Assume that your measurement has a 5% error.

Then, for all you know the edge could be as long as 11in or as short as 10 in. In light of this what are the maximum and minimum values for the carpet's area?

What percent error in the carpet's area and how does this relate to the error of its edge?

Is there any relation of the error in the carpet area to that of its edge's error?

The Setup: A piece of wire of length 10 cm is cut into two (not
necessarily equal length) pieces. One piece of length x cm is made
into a circle and the rest is made into a square.
1. Express the sum of the areas of the square and circle as a
function of x
2. For what x-value is maximum area achieved?
3. For maximum area, how should the wire be bent?
4. Find the critical values of your...

1. A spaceship passes you at a speed of 0.760c. You measure its
length to be 26.6 m. How long would it be when at rest?
2. If you were to travel to a star 112 light-years from Earth at
a speed of 2.59×108 m/sm/s , what would you measure this
distance to be?

I
have 6 questions
1) a spaceship passes you at a speed of 0.8c you measure its
length to be 25.4m how long would it be when at rest
2) a certain type of elementary particle travels at a speed of
2.73x10^8m/s at this speed the average life-time is measured to be
4.67x10^-6s what is the particles lifetime at rest
3) if you were to travel to a star 81 light-years from earth
at a speed of 2.8x10^8m/s what would...

CASE STUDY – Jacobson Carpet Company
In January 2002, Ms. Mary Lewis was preparing to meet with Mr.
Carpenter, President of Jacobson Carpet Company.
Ms. Lewis assumed that the meeting was related to the recent
Board of directors of the company. As a direct assistant
to the President, she knew from experience that this type of
meeting often resulted in a project to be studied. Her
expectation was confirmed as soon as Mr. Carpenter began to
inform her of the...

1.A population of alpacas all have an identical fur
length phenotype. During a particularly cold winter, longer fur
would be beneficial as it would provide them with greater
insulation. Select the correct answer given this information.
A. the alpacas will evolve by natural selection as
longer hair would be favorable in their environment.
B. a mutation for longer fur will likely develop in
this population.
c. alpacas will longer fur will likely migrate into
this population as they have a...

Activity 1: Scientific Reports
You may have heard the question “If a tree falls in a forest and
no one is around to hear it, does it make a sound?” A similar
question can be asked about experiments. “If a researcher performs
an experiment and never publishes the result has science been
performed?” Many people would say no because science is the
accumulation of knowledge. If the results of an experiment are not
published, knowledge is not gained. The final...
