gold because it has highest boiling point so it can conduct the heat
Well I think B hope this helps
Answer:
I'm sorry I don't have a answer but I like your pfp
Momentum, p = m.v
m of the girl = 60.0 kg
m of the boat = 180 kg
v of the girl = 4.0 m/s
A) Momentum of the girl as she is diving:
p = m.v = 60.0 kg * 4.0 m/s = 24.0 N/s
B) momentum of the raft = - momentum of the girl = -24.0 N/s
C) speed of the raft
p = m.v ; v = p/m = 24.0N/s / 180 kg = -0.13 m/s [i.e. in the opposite direction of the girl's velocity]
Answer:
c) may also be conserved
Explanation:
Momentum is conserved in both elastic and inelastic type of collisions.
But the differences is that:
In an ELASTIC type of collisions, KINETIC ENERGY IS ALSO CONSERVED.
whereas, In an INELASTIC type of collision, KINETIC ENERGY IS NOT CONSERVED.
So unless until type of collision is specified, we can not say anything about the conservation of kinetic energy after collision.
Hence, may also be conserved is the appropriate option here.
