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.

Heterogeneous mixture is a substance that does not have a chemical formula and has more than one fase and the examples are water and oil because of the two different colors of fases, italian dressing is also another example because it has more than one different colors of fases.
Answer:
the kinetic energy lost due to friction is 22.5 J
Explanation:
Given;
mass of the block, m = 0.2 kg
initial velocity of the block, u = 25 m/s
final velocity of the block, v = 20 m/s
The kinetic energy lost due to friction is calculated as;
Therefore, the kinetic energy lost due to friction is 22.5 J
Answer:
The same numbers of shell
Explanation:
Elements in the same periods have the same numbers of shells of electrons. This implies that across the period, electrons are filled into the same shells until it filled. So, As you move across the period, elements have the same number of shells
