Spacecraft a is in an elliptical earth orbit having the following orbital elements: e = 0.1, ω = 40°, i = 60°, ω = 30° and θ = 50° , h = 65,000 km2 /s and spacecraft b is in a nearly circular earth orbit with the following orbital elements: e = 0.02, ω = 20°, i = 20°, ω = 110° and θ = 40° , h = 61,000 km2 /s a) determine the relative position, velocity and acceleration of spacecraft b relative to a, measured in local vertical/local horizontal commoving coordinate system of spacecraft a. b) plot the two orbits and show the location of each satellite in the geocentric equatorial frame

**urgent** roberto plans to use two transformers to reduce a voltage of 120 v to 4 v. he uses a transformer that has 300 coils in the primary winding and 50 coils in the secondary winding. he has four other transformers, as listed in the table. which transformer should roberto use to have an ending voltage of 4 v? a- w b-xc- yd- z

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
