Sta je projektil i po cemu je dobio ime? (2 boda)

Projektile (lat.:„proicere“ = „werfen, vor sich werfen“)

A shell (projectile) is a payload-carrying projectile, which, as opposed to a bullet, contains an explosive or other filling, though modern usage includes large solid projectiles previously termed shot (AP, APCR, APCNR, APDS, APFSDS and Proof shot). Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used.

Shells are usually large rounds fired by artillery, armored fighting vehicles (including tanks), and warships.

Shells usually have the shape of a cylinder topped by an ogive-shaped nose for good aerodynamic performance, possibly with a tapering base; but some specialised types are quite different.

projektil (fr. projectile)
svako telo bačeno nekom silom, naročito: topovsko zrno, puščano zrno

svako telo bačeno nekom silom koji proizvodi udar..
potice od latinske reci "proicere"

ps: zar ne bi bilo bolje da su odgovori na srpskom jeziku

Osnovna razlika izmedju aktivnih i poluaktivnih raketa je? (3 boda)

Semi-active radar homing, or SARH, is a common type of missile guidance system, perhaps the most common type for longer range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal – provided by an external ("offboard") source – as it reflects off the target.

NATO brevity code for a semi-active radar homing missile launch is Fox One

Active homing

Active homing uses a radar system on the missile to provide a guidance signal. Typically electronics in the missile keep the radar pointed directly at the target, and the missile then looks at this "angle" of its own centerline to guide itself. Radar resolution is based on the size of the antenna, so in a smaller missile these systems are useful for attacking only large targets, ships or large bombers for instance. Active radar systems remain in widespread use in anti-shipping missiles, and in "fire-and-forget" air-to-air missile systems such as AMRAAM and R-77
