I believe the correct answer is 40 cm.
Answer:
A) R = (200 i ^ + 100 j ^ + 30k ^) m
, B) L = 223.61 m
, C) R = 225.61 m
Explanation:
Part A
This is a vector summing exercise, let's take a Reference System where the z axis corresponds to the height (flights), the x axis is the East - West and the y axis corresponds to the North - South.
Let's write the displacements
Descending from the apartment
10 flights of 3 m each, the total descent is 30 m
Z = 30 k ^ m
Offset at street level
L1 = 0.2 i ^ km
L2 = 0.1 j ^ km
Let's reduce everything to the SI system
L1 = 0.2 * 1000 = 200 i ^ m
L2 = 100 j ^ m
The distance traveled is
R = (200 i ^ + 100 j ^ + 30k ^) m
Part B
The horizontal distance traveled can be found with the Pythagorean theorem for the coordinates in the plane
L² = x² + y²
L = √ (200² + 100²)
L = 223.61 m
Part C
The magnitude of travel, let's use the Pythagorean theorem for the sum
R² = x² + y² + z²
R = √ (30² + 200² + 100²)
R = 225.61 m

Answer:
Density is the ratio between the mass and the volume of a body. Relative density, on the other hand, is the ratio between the density of an object (substance) and the density of some other reference object (substance) at some given temperature.
Explanation:
Answer: (B) your mass is essentially unchanged but your weight is less than on Earth.
Explanation:
Well, firstly we have to explain the difference between the concepts of mass and weight:
<u>-Mass</u> 
is the amount of matter that exists in a body, which only depends on the quantity and type of particles within it. This means mass is an intrinsic property of each body and <u>remains the same regardless of where the body is located. </u>
<u>-Weight</u> 
is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass of the body by the acceleration due gravity 
in that place and is mathematically expressed as:
So, according to this explanation and since the Earth and Mars have different values of acceleration due gravity (in fact, Mar's is less than Earth's), <u>your weight has changed, but not your mass.</u>
