On a floor directly underneath a second-floor balcony, there are several spherical drops of blood about 6 mm in diameter. Which statement best accounts for the drops?

Respuesta :

The answer is the drops dripped from a bloody knife about 2 ft above the ground. If it's a hard floor, and the drops are totally spherical, they didn't drib from very high. Drops will scatter external if they released from much height on to a hard surface.
