design an experiment to measure the effects of chromatic aberration? Just a simple procedure, thanks.

In a Compton scattering experiment, an x-ray photon scatters through an angle of 16.6

Does the boiling point of water differ with different concentrations of salt?

For this experiment, complete steps (a)–(c) of the checklist for planning experiments as it appears in the Design and Analysis of Experiments text by Dean and Voss.

CHECKLIST
(a) Define the objectives of the experiment.
(b) Identify all sources of variation, including:
(i) treatment factors and their levels,
(ii) experimental units,
(iii) blocking factors, noise factors, and covariates.
(c) Choose a rule for assigning the experimental units to the treatments.

One-Factor-at-a-Time (OFAAT) and Design of Experiment (DOE)

• Per the textbook, trying to understand factors that impact the outcomes of business process is an important aspect of improving business operations. Conventional wisdom plans experiment one-factor-at-a-time (OFAAT).

Compare and contrast the main advantages and disadvantages of OFAAT and DOE and select the approach (for example, OFAAT or DOE) that you would use in order to obtain effective business process. Provide a rationale for your response

A wire 80 cm long carries 11 A of current. From this wire, a loop of 90-turns is made and placed in a magnetic field of 6.50 Tat an angle of 35˚. In first experiment, a square loop is formed and in the second experiment, a circular loop is formed with same number of turns. Calculate the torque in each loop. Which loop produces more torque-the circular loop or the square loop? What is the reason for this change of torque in both loops?   

Suppose the owners of a new bed and breakfast establishment are interested in conducting an experiment to determine effective advertisement strategies for increasing the number of reservations. The bed and breakfast owners intend to rotate advertisements for 12 weeks between a travel website, a travel magazine and a local billboard. Customers making reservations will be asked if they saw the advertisement. In this experiment, the independent variable has how many levels?

A) 1

B) 2

C) 3

D) 4

E) 0

In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with charges measured in a fictitious unit called a zeet (Z). Drop Charge (Z) A 2.55×10−14 B 4.59×10−14 C 5.10×10−14 D 5.61×10−14 E 7.65×10−14 What is the charge on an electron in zeets? Express your answer in zeets using two significant figures.

A.) Dr. Smith conducts an experiment in which participants are asked to respond to fine lines so that the smallest line-width the participant can detect is identified. This best illustrates the _____ relationship.

For one of your trials during the equilibrium experiment at room temperature as described in the lab manual. You determine the following for Tube #1 while performing the experiment as described in the lab manual. For the standard solution in tube # 5 the absorbance value is 0.789 and the [FeSCN2+]eq of the standard is 0.0002000M. The following resuts apply to tube #1:

[Fe3+]o - 0.00100308 M

[SCN-]o - 0.00040005 M

absorbance tube 1 - 0.1657 au

Determine Kc.
