Answer:
Yes it does.
Explanation:
"The North Magnetic Pole moves over time due to magnetic changes in Earth's core.
" - Wikipedia.
It does move around as the magnetic north does.
I see the word "when..." kind of fading out at the end of the first line.
Whatever comes after it may be important.
If you're just supposed to copy the expression into the box,
then the problem is that you left the 'e' out of it.
I'm guessing that you're supposed to enter whatever the expression becomes
when either N₀ or ' t ' has some special value that's in the first line.
Just taking a wild guess here . . . . .
If it's "Enter the expression ..... , when t=0 ." ,
then the correct answer in the box is N₀ .
But that's just a wild guess. As I pointed out, you cut off
the picture in the middle of the word 'when', and I've got
a hunch that there's something important after it.
This question can be solved with the help of the equations of motion.
A) The Frisbee will remain in the air for "5.87 s".
B) The frisbee will go "29.4 m" down the range.
A)
To calculate the time, the frisbee will remain in the air, we will use the second <em><u>equation of motion</u></em>, for the vertical motion.
![h = v_it+\frac{1}{2}gt^2\\\\](https://tex.z-dn.net/?f=h%20%3D%20v_it%2B%5Cfrac%7B1%7D%7B2%7Dgt%5E2%5C%5C%5C%5C)
where,
h = height = 169.2 m
vi = initial velocity's vertical component = 0 m/s
g = acceleration due to gravity = 9.81 m/s²
t = time = ?
Therefore,
![169.2\ m = (0\ m/s)(t)+\frac{1}{2}(9.81\ m/s^2)t^2\\\\t = \sqrt{\frac{(169.2\ m)(2)}{9.81\ m/s^2}}](https://tex.z-dn.net/?f=169.2%5C%20m%20%3D%20%280%5C%20m%2Fs%29%28t%29%2B%5Cfrac%7B1%7D%7B2%7D%289.81%5C%20m%2Fs%5E2%29t%5E2%5C%5C%5C%5Ct%20%3D%20%5Csqrt%7B%5Cfrac%7B%28169.2%5C%20m%29%282%29%7D%7B9.81%5C%20m%2Fs%5E2%7D%7D)
<u>t = 5.87 s</u>
<u />
B)
Now, we will calculate the horizontal range by applying the equation for constant motion. Because the velocity in the horizontal direction will remain constant due to no air resistance
s = vt
where,
s = horizontal range = ?
v= initial velocity's horizontal component = 5 m/s
t = time = 5.87 s
Therefore,
s = (5 m/s)(5.87 s)
<u>s = 29.4 m</u>

Answer:
speed- distance traveled per unit of time.
velocity-rate of change of its position
acceleration-rate of change of the velocity
Explanation:
Answer:
I'm pretty sure it's the third one where velocity goes from positive to negative
Explanation:
the positive velocity is before the object hits the ground and the negative is after
