Larva, pupa, and egg are insects life cycle
Spore, seed, fruit, and cone are animal life cycle
The answer is 138.75 kgm/s
Impulse (I) is the multiplication of force (F) and time interval (Δt): I = F · Δt
It is given:
m = 0.25
F = 18,500 N = 18,500 kgm/s²
Δt = 0.0075 s
I = ?
I = F · Δt = 18,500 5kgm/s² * 0.0075 s = 18,500 * 0.0075 kgm/s² * s = 138.75 kgm/s
take the volume that is submerged. That's the volume of water displaced.
but the volume of submerged is different in those two
so buoyancy force is different in those two
weights are the same
probably. since the densities* are different.
In question it says wights are the same and diffferent volumes
so it seems that the one with more density should have a lower buyonacy force
but you said that when an object floats the buoyancy force equals weight,so since both objects have the same weight,then buoynacy force should be equal in those two
The more dense object will float with a greater percentage of its volume immersed, not less.
2) If they have the same MASS, the more dense one will have less VOLUME
Explanation:
Momentum is conserved:
m₁v₁ = m₂v₂
(42.8 kg + 31.5 kg + 25.9 kg) (19.8 m/s) = (31.5 kg + 25.9 kg) v
v = 34.6 m/s
