Answer:
The girl will move with constant velocity
Explanation:
If after a certain time t_0 the velocity of the girl is v_0 =gt_0 and the upward force on the girl due to rope is mg ,where g is gravitational acceleration. Then the girl will move down with the constant velocity v_0 .
The girl will move with constant velocity,as explained above.
To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ
sec θ = 1 / cos <span>θ
csc </span>θ = 1 / sin θ<span>
Using these identities:
</span>cot θ ∙ sec θ = (cos θ / sin θ ) (<span> 1 / cos </span><span>θ)
</span>
We can cancel out cos <span>θ, leaving us with
</span>cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc <span>θ</span>
It would be A: Have a greater height.
The higher the wave the higher the energy!
That's called 'parallax'.
To see it happen, go outside, hold your arm straight out in front
of your face and stick your thumb up. Close one eye, and notice
where your thumb appears against the houses across the street.
Now, don't move your arm, but just close the first eye and open
the other one. You'll see your thumb jump in front of a different
house. The angle that your thumb appeared to move is its parallax.
