-Geographic north and south poles are determined by the earth's spin.
-Magnetic north and south is determined by the direction a compass points.
Hope this helps,

We can approach this in another way.
We know that sin(∅) = height / hypotenuse.
Thus, for x, height is 1 and hypotenuse is 3. Using Pythagoras theorem,
3² = 1² + b²
b = √8
cos(x) = b/hypotenuse
cos(x) = √8 / 3
Now, lets consider y:
sec(y) = 1 / cos(y) = 1 / base / hypotenuse = hypotenuse / base
The hypotenuse is 25 and the base is 24. We again apply Pythagoras theorem to find the third side, which works out to be:
height = 7
sin(y) = height / hypotenuse
sin(y) = 7/25
Now, sin(x + y) =
sin(x)cos(y) + sin(y)cos(x)
= (1/3)(24/25) + (√8 / 3)(7/25)
= 8/25 + 7√8/75
= (24 + 14√2) / 75
The answer is D.
Conduction is the transfer of thermal energy by means of <em>direct contact</em>. Particles that are warmer have more energy so the move faster. When these warm particles touch cold particles, they collide with them and transfer energy to them and they continue to pass it on to the other particles next to them.
Answer:
Explanation:
Let +y is upward direction and backward be +x direction
then we have given data
From equation simple motion we find the time
So
To get the distance between the point the package ejected to the point it the ground.
Now we have to get the distance the helicopter travels during same interval
Now to get the distance between the package and helicopter when package hit the ground
