Net electric field-magnitude and direction
Two charges are placed on the x axis. One charge (q1 = +18.5 µC) is at x1 = +3.0 cm and the other (q2 = -13 µC) is at x2 = +9.0 cm. Find the net electric field (magnitude and direction) at the following locations.
(a) x = 0 cm
(b) x=+6.0 cm

A hypothesis test for a population proportion p is given below: Ho: p = 0.25 vs. Ha: p NE 0.25 (NE means not equal) For sample size n=100 and sample proportion p = 0.30, compute the value of the test statistic:

Based on new water standards for manufacturers in the region, they wanted to see if there was a change in contamination in crayfish. What are the appropriate null and alternative hypotheses? (NE means not equal.)
A 1000-hertz tone issuing from a loudspeaker has an intensity level of 100 dB at a distance of 2.5 m. If the speaker is assumed to be a point source, how far from the speaker will the sound have undiminished intensity levels (a) of 60 dB and (b) b

(a) If a sample of gold with a mass of 2.478 g, is pressed into a leaf of 8.423 μm thickness, what is the area (in m2) of the leaf? (b) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.400 μm, what is the length (in m)
The acceleration (a) of a slider block and its displacement (s) are related by the expression, a = k s , where k is a constant. The velocity v is in the direction of the displacement and the velocity and displacement are both zero when time t is z
Air is compressed in a steady-flow compressor via a polytropic process from 15 psia and 60ºF (State 1) to 75 psia and 294ºF (State 2). Show the compression process on P-v and T-s diagrams.
