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.

Answer: SI Unit is meters per second(m/s)
Explanation:
The three units of speed are:
1. meters per second(m/s)
2. kilometers per hour(km/hr)
3. miles per hour(mph)
SI Unit is meters per second(m/s)
It is D) raising a 200 kg box to a height of 2 m using an inclined plane of length 8 mI think .
Speed is equal to distance traveled divided by the time. So it's 3.5 m/s
