While Earth is only the <u>fifth largest planet in the solar system</u>, it is <u>the only world </u>in <u>our solar system</u> with the life we know or are starting to know of, for example, us as human beings. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. Other planets such as Jupiter are not so likely to have life like us there, for it is full of gas we don't breathe, and gases which are harmful to us, unlike the oxygen we have here on earth.
The displacement should be a negative value. since your zero point is where you dropped it. The answer is C
Displacement in Space
It is the length of a body's real route. It is the shortest distance between the body's final and beginning positions.
It's a number with a scalar value. It's a quantity with a vector.
It can't possibly be negative. It might be a negative number, a zero number, or a positive number.
Average velocity is given by the ratio of total displacement /total time taken in order to do that
thus it will be
30.5-50.0/3 = 6.5 m/s
Overweight:25 to 30, obese: over 30
