Answer:
today's species evolved from those of the past.
Explanation:
By comparing fossils of a specie from long ago to those of today, we can conclude that today's species evolved from those of the past.
- Fossils are the preserved remains of ancient life forms found within sedimentary bed layers.
- These fossils helps scientists to understand ancient life forms.
- According to the discovery of Charles Darwin, organisms have evolved and are still evolving.
- Understanding past life forms gives a way to characterize present day species better.
Answer: Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
Weight of an object is defined as attraction force due to gravity
so here we will have
now we know that
mass = 15 kg
now acceleration due to gravity is given as
so here acceleration due to gravity is 9.8 m/s^2
