Evaporation. The glass of water was less full after 10 minuets because the water got evaporated
Air resistance, also called drag, acts upon a falling body by slowing the body down to thr point where it stops accelerating, and it falls at a constant speed, known as the terminal volocity of a falling object. Air resistance depends on the cross sectional area of the object, which is why the effect of air resistance on a large flat surfaced object is much greater than on a small, streamlined object.
Answer:
It is very important because scientists, especially the ones with empirical experiments and results, are prone to error and the empirical data is in need to be under strict observation done not only by many scientists but also by expermiented ones. This guards everybody to change the parameters suddenly which can affect the real results of an experiment
Explanation:
Venus is closer, relatively the same size as the earth and has an atmosphere
Answer:
Weight at the surface of Jupiter's moon Io is 8.13 N .
Explanation:
Given :
Acceleration due to gravity at the surface of Jupiter's moon is
.
Weight of watermelon in earth ,
.
Acceleration due to gravity at the surface of earth is
.
We know , weight is given by :

Therefore , mass at the surface of Jupiter's moon Io is :

Hence , this is the required solution .
