Hello for a laboratory experiment we used strain gauges to measure the internal pressure of a coke can. Our instructor told us one of the sources of error would be not aligning the gauges perfectly. Why would this cause error in the experiment? Is there any other sources of error as well.

Assume that a new intervention has been developed using a new approach to social skills training to help individuals with Asperger’s syndrome. How would you design an experiment to test the intervention? Consider the type of experiment, exposure, measurement, ordering, assignment to condition, and comparison groups.

Give an example of an experiment to determine the focal length of a concave lens.

(Note that such a lens cannot project a real image onto a screen by itself, so you will need to use a two-lens system). List all materials use and describe how/why the experiment works.

A linear transformation from R3-R4 with the V set of vectors x, where T(x)=0, is V a subspace of R3?

Astronomy question.

Which star is coolest?

a. M8 V

b. K1 I

c. A7 III

d. B3 V

Prove or disprove: Between any n-dimensional vector space V and Rⁿ there is exactly one isomorphism T : V → Rⁿ .

Design and simulate a DC power supply using Zener diodes to produce 15 V if you have two Zener diodes of Zener voltage 7.5 V when the dc link voltage 24 V. The assignment report should include the following information: Assignment objectives, introduction, design procedure, simulation with simulation results, and conclusion.

An ac generator with a frequency of 30.0 Hz and an rms voltage of 14.0 V is connected to a 65.0 μF capacitor.

1. What is the maximum current in this circuit?

2. What is the current in the circuit when the voltage across the capacitor is 4.30 V and increasing?

3. What is the current in the circuit when the voltage across the capacitor is 4.30 V and decreasing?

True/False Question: If sppan{u,v}=W where u not equal to v. Then dim(W)=2.

Answer: False

Reasoning let u=1, v=2 then span(1,2}=R but dim(R)=1 not 2.

I know the answer is false. please tell me whether my reasoning is correct.
