Answer:
v = 10 m/s
Explanation:
given,
Mass of large fish, M = 5 Kg
speed of swimming, v' = 2 m/s
mass of small fish, m = 1 kg
speed of the fish = v
using conservation of momentum
m v + M v' = M u' + m u
final speed of both the speed is zero.
- 1 x v + 5 x 2 = 0
negative sign is used because small fish is moving in opposite direction.
now,
v = 10 m/s
hence, the speed of the small fish is equal to 10 m/s.
Answer:
c) Anti-top
Explanation:
Protons are particles which belong to the hadron group of particles. The antimatter equivalent particle is antiproton
Electrons are particles that belong to the fermion group of particles. The antimatter equivalent is antielectron
Antitop quarks are particles that belong to the group family of particles. They are the antimatter equivalent of top quarks.
Gluons are particles that belong to the group of particles called bosons.
Tau neutrinos are particles that belong to the fermion group of particles. The antimatter equivalent is Tau antineutrino.
Answer:
2465 J/g
Explanation:
The amount of energy required to boil a sample of water already at boiling point is given by
where
m is the mass of the water sample
is the specific latent heat of vaporization of water
In this problem, we know
Solving the equation for , we find
There is no direct relationship between power
and either of those quantities.
