Ahiker walks in the direction that a compass needle points. in which location would the hiker's direction deviate the most from geographic north? assume that the compass needle is affected only by earth's magnetic field.
a. near the equator
b. within the arctic circle
c. within the continental united states
d. near an ocean coastline

D. near an ocean coastline

Explanation:

The magnetic needle of a compass can be deviated by the magnetic field that the ocean has, this is important to remember because eventhough it´s not a big difference but it is significant enough to keep it in mind. Ocean can attract the magnetic needle of the compass and create a deviation on it.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

it was given as a lesson and guide for prayer.
