Answer:
The total momentum of the system is 1.45 kg*m/s.
Explanation:
The total momentum of the system is given by:
Where:
m: is the mass
v: is the velocity
d: is for duck
b₁: is for baby duck one
b₂: is for baby duck two
b₃: is for baby duck three
Therefore, the total momentum of the system is 1.45 kg*m/s.

Answer:
The mass of the copper is 3.00kg
Explanation:
Kinetic energy = (1/2) (mass) (speed)²
The rock's kinetic energy is not
(1/2) (4 kg) (10 m/s)²
= (1/2) (4 kg) (100 m²/s²)
= 200 Joules .
It may be more, or it may be less. The only thing
we can be sure of is that it is not 200 Joules.
Answer:
<em>we can say that that in an increasing order, the body is less dense than the glycerine, and the glycerine is less dense than the kerosene.</em>
<em></em>
Explanation:
If the body sinks below the kerosene level to float in glycerine, then it means that the kerosene is denser than glycerine. This is because bodies will float higher in a denser fluid that a less denser fluid. Also, since the body floats in kerosene and glycerine, then the body is less dense than the kerosene and the glycerine. Finally, <em>we can say that that in an increasing order that the body is less dense than the glycerine, and the glycerine is less dense than the kerosene</em>
