Maria is a geologist studying a particular rock layer in a local mountain range. One of her colleagues had previously discovered

an uncommon dinosaur fossil in the same rock layer. Maria uses the known age of the fossil to determine the age of the rock layer she is studying.

Answer:

Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.

So, Maria is using relative dating method

It's the only answer

At an airport, two business partners both walk at 1.5 m/sm/s from the gate to the main terminal, one on a moving sidewalk and th
Musya8 [376]

Answer:

v=0.8m/s

Explanation:

From the question we are told that

Distance d=1.5m/sm/s

Time  t_1=60s  

Time  t_2=90s  

Generally the  the equation for the distance traveled is mathematically given as

d=vt

d=1.5*90

d=138m

Generally equation for speed of side walk is mathematically given as

d=(v+u)t

v=\frac{d}{t}-u

v=\frac{138}{60}-1.5

v=0.8m/s

a teacher drives from school to the mall. then she goes to the doctors office for a physical examination. what is the magnitude
Amanda [17]

The magnitude of the teachers displacement is the difference between

the location of the school and the location of the doctors office

The reason behind the above expression are explained as follows

The known locations of the teacher;

Initial location; The school

Second location; The mall

The eventual location; The doctors office

The required information;

The magnitude of the teachers displacement

The method of obtaining the displacement of the teacher;

Qualitatively, the displacement of the teacher can be obtained by applying the definition of displacement as follows;

The definition of displacement is an object's change in position, given by the difference between its start and finish locations

According to the definition of displacement, therefore, the magnitude of

the teachers displacement is the distance between the school and the

doctors office which is given by the difference between the coordinates of

the location of the school and the location of the doctors office

The magnitude of the displacement of the teacher = The coordinate of the location of the doctors office - The coordinate of the location of the school
