Answer:
The equatiom of kinetic energy is 1/2×m×v² where m represents mass and v is velocity :
The unit for kinetic energy is measured in Joules (J).
Answer:
Earthworm lives in the soil, eats the soil which has organic matter such as decaying vegetation or leaves and crawls. While housefly lives in dirty places, feeds on faeces and flies.
Hope I get a brainliest answer.
Answer:
v = 8 [m/s]
Explanation:
Debemos determinar la velocidad promedio, esta velocidad se define como la relacion entre la distancia recorrida sobre un determinado tiempo.
De esta manera tenemos la siguiente expresion:
v = x/t
donde:
v = velocidad [m/s]
x = distancia = 400 [m]
t = tiempo = 50 [s]
v = 400/50
v = 8 [m/s]
