The maximum allowable compression in members ab and ac is 3.2 kn, and the maximum allowable tensile force in cable ad is 3.2 kn. find the maximum mass, w, such that none of the members or cables exceed their maximum allowables, given: l1 = 8 m, l2 = 4 m, l3 = 10 m, l4 = 8 m

that would be because of both gravity and friction. so     c

it is a negative acceleration

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.
