ANOTHER RUNNING DOG
Explanation:
In the given question it is to find a suitable reference point to describe the motion of dog. Here I could suggest that it is better to compare the dog with another running dog to create the relative speed difference to get a reliable motion variation.
Because the motion of dog is in the linear with respect to the another dog and to the acceleration produced by the dog in the required interval is easy to calculate with respect to another dog which is already in motion.
Hence, I suggest that Motion of dog can be analysed better by analyse the motion variation of dog with another dog running.
Answer:
Gravity pulls objects toward Earth.
The rate of acceleration due to gravity is 9.8 m/s2.
Weight on Earth’s surface is a result of gravity’s pull.

these are the answers for e2020
Like a then it would be A something I guess it goes like that
Newton first law state that anything in motion or rest will remain in motion or in rest until an external force is applied
Newton third law of motion state that every action have equal and opposite reaction
Answer:
Explanation:
The standard unit of displacement in the International System of Units ( SI ) is the meter (m).
