What coefficients would balance the following equation? __c2h6 + __o2 → __co2 + __h2o a. 1c2h6 + 5o2 → 2co2 + 3h2o b. 2c2h6 + 5o2 → 4co2 + 6h2o c. 2c2h6 + 7o2 → 4co2 + 6h2o d. 2c2h6 + 10o2 → 4co2 + 6h2o

Space vehicles traveling through earth's radiation belts can intercept a significant number of electrons. the resulting charge buildup can damage electronic components and disrupt operations. suppose a spherical metallic satellite 1.3 m in diameter accumulates 3.0 µc of charge in one orbital revolution. (a) find the resulting surface charge density. (b) calculate the magnitude of the electric field just outside the surface of the satellite, due to the surface charge.

Ascrew incorporates which other simple machine? lever wheel and axle inclined plane pulley

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
