Answer: Geologists map out <em>data </em>from previous earth quakes to determine earthquakes risk.

Explanation:

Geology is the study of earth. Also, it is the study of how Earth's materials, structures etc are changed over time.

Geologist is a scientist who studies the structure of earth, rocks, soil, fossils and earthquake. So, they map out the data from previous earthquakes to determine earthquake risk.

While driving north at 25 m/s during a rainstorm you notice that the rain makes an angle of 38° with the vertical. While driving
Natali [406]

Answer:21.33^{\circ}

Explanation:

Given

velocity of driver v_1=25 m/s w.r.t ground towards north

driver observes that rain is making an angle of 38^{\circ} with vertical

While returning v_2=25 m/s w.r.t. ground towards south

suppose u_1=velocity of rain drop relative car while car is going towards north

u_2=velocity of rain drop relative car while car is going towards south

z=vector sum of u_1 & v_1

Now from graph

\tan 38=\frac{v_1+v_2}{u_2}

u_2=\frac{25+25}{\tan 38}=64 m/s

z=\vec{u_2}+\vec{v_2}

therefore magnitude of z is given by

|z|=\sqrt{u_2^2+v_2^2}

|z|=\sqrt{64^2+25^2}

|z|=68.70 m/s

\tan A=\frac{v_2}{u_2}

\tan A=\frac{25}{64}=0.3906

A=21.33^{\circ}

Thus rain drops make an angle of 21.33^{\circ} w.r.t to ground

a car moves 6 km east, then 4km north. what was the distance covered? What was the total displacement?
Aliun [14]

Answer:

distance= 10 km

displacement= 7.21 km

Explanation:

distance= scalar (only magnitude)

displacement= vector (magnitude & direction)

distance= 6 km+ 4 km

= 10 km

displacement= shortest difference btwn 2 pts=

sqrt( 6^2+4^2)

sqrt(52)

7.21 km
