The above stress is approximated by a sinusoidal function (i. e. sine wave) with a mean 3,526 kPa and amplitude 260 kPa at a frequency of 6 Hz. At a second flight condition, the stress had an additional sinusoidal component (i. e., in addition to the first sinusoidal function above) that has 3 times the frequency of the first component and half of the magnitudes of the first component. The format for the Fourier series for the stress signal for this flight condition is given below: y(t)2 = { z1 + z2 * sin (d2*π t) + z3 * cos (d3*π tπt) } kPa. Where the second term corresponds to a lower frequency compared to the third term. Provide the value of z1 (using 2 decimal places).

the answer for apex is the lowest

answer and explanation;

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
