Answer: because of air resistance. See explanation for further details.
Explanation: Galileo performed an experiment to proof that the time of descent of two different masses is independent of time.
But in reality this is most likely not true because of air resistance and other fluid frictional effects in consideration.
If the experiment is performed in a vacuum, it will always be true that time is independent of masses of two falling objects.
The layer of soil that contains the most organic material is called the a horizon.
Your answer will be A.
With smaller mass, object should be more denser in order to have equal landmass.
Mars should be more denser, if it has equal landmass.
But in reality, it's landmass is not equal 'cause it's density is about 72% of that of earth.
Hope this helps!
Answer:
0.174413400763 s
Explanation:
L = Length of rod = 90 m
Speed of sound in air = 344 m/s
= Density of brass = 8600 kg/m³
Y = Young's modulus = 
Velocity of sound in a material is given by

Time taken in brass

In air

The time interval is
