Afence post of mass m = 8 kg supports a fence with three lengths of barbed wire. the bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. each of these three wires has the tension on it. for this problem, assume that the force exerted by these wires is purely horizontal. an additional guy wire is used to keep the pole upright with a tension of fa = 460 n. the guy wire attaches to the post at a point h = 0.89 m above the ground and makes an angle of θ = 55 with respect to the horizontal.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

magnets not strong enough

explanation:

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.

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.
