Answer:
Cuando la Tierra se formó era una bola de materiales incandescentes, fundidos, que se fueron colocando en capas según su peso, ya que los materiales más pesados se fueron hundiendo hacia el interior de la protoTierra, y los más ligeros se fueron hacia el exterior y alrededor del planeta.
Explanation:
Answer:
17.78 m/s
Explanation:
Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.
1 km = 1000 m, so 16 km is 16000 m
0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.
Thus:
average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s

Answer:
1) A = 0.25 m², 2) V = 0.5 m³, 3) m = 1500 kg, 4) W = 14700 N,
5) P = 58800 Pa
Explanation:
1) The area of the base is square
A = L²
A = 0.5²
A = 0.25 m²
2) The block is a parallelepiped
V = A h
V = 0.25 2
V = 0.5 m³
3) Density is defined
rho = m / V
m = rho V
m = 3000 0.5
m = 1500 kg
4) The weight of a body is
W = mg
W = 1500 9.8
W = 14700 N
5) The pressure is
P = F / A
in this case the force is equal to the weight of the body
P = 14700 / 0.25
P = 58800 Pa
