when one substance is changed into another substance,so many properties are changed.
a-physical properties
b-chemical properties
c-nuclear properties
the properties will be called physical properties if there will be change of states of matter which includes melting,boiling,sublimation etc where the substance has gone no change in chemical composition.
the property will be called chemical if there will be change in its chemical configuration and both the initial and final products are different in their structures
the property may be nuclear when there will be change in the nuclear parameters in the initial and final products. one can take an example of transmutation when atom is converted into another atom through projectiles.
The combined speed of the plane and the wind is 249.35 km/h.
<h3>
Relative speed</h3>
The relative speed of the plane due to speed of the wind is calculated as follows;
Let the direction of the plane be horizontal direction.
<h3>Speed of the wind</h3>
The speed of the wind is calculated as follows;
<h3>Combined speed</h3>
The combined speed of the plane and the wind is calculated as follows;
V = 275 km/h - 25.65 km/h
V = 249.35 km/h
Thus, the combined speed of the plane and the wind is 249.35 km/h.

Answer:
5.60 m/s
Explanation:
His initial potential energy is equal to his final kinetic energy.
mgh = 1/2mv^2
2gh = v^2 . . . . . . . multiply by 2/m
v = √(2gh) = √(2(9.81 m/s²)(1.6 m)) = √(31.392 m²/s²)
v ≈ 5.60 m/s

The mass is irrelevant in the equations we typically use for this purpose.
Energy is never created and energy never is destroyed
