Answer:
0.00034 m
Explanation:
Since the length of the aluminium bar, L is given by , L = 1.0000 + 2.4 × 10⁻⁵T and T = 14.1°C, we substitute the value of T into L. So, we have L = 1.0000 + 2.4 × 10⁻⁵ × 14.1°C = 1.0000 + 0.0003384 = 1.0003384 m. The change in length is thus 1.0003384 - 1.0000 = 0.0003384 m ≅ 0.00034 m

The word momentum means mass and velocity taken together.
Mass is an intrinsic basic physical quantity which tells us about the amount of matter contained in a body. It is a scalar quantity and it is measured in kilogram(Kg).
Velocity is the rate of change of displacement . It is defined as displacement per unit time. It is a vector quantity and measured in meter per second (m/s)
The product of mass and velocity is momentum. When a body possesses both mass and velocity we say that it has momentum. It is a vector quantity. Its unit is kg m/s
Mathematically we write momentum as,
P = mv
Mathematically we write momentum a
Where, P = momentum
m = mass
v= velocity.
When a force is applied on a body, it changes its momentum. The relationship between force and momentum is given by Newton's second law of motion which states that the rate of change of momentum is directly proportional to the force applied,
F = Δp /Δt
Where F= force
Δp = change in momentum
Δt = time taken for the change in momentum to occur.

Answer:
In my mind when I hear the word momentum it comes that it is the product of mass and velocity.
