The package should be dropped <u>678 m</u> short of the target.
A package dropped from a plane which is moving at a speed v, has a horizontal velocity equal to the horizontal velocity of the plane. It has a parabolic trajectory, traversing a horizontal range x while it falls through a vertical height y.
The package has no initial vertical velocity, and it falls through a height y under the action of the acceleration due to gravity g.
Use the equation,

Write an expression for t, the time taken for the package to fall through y.

Substitute 100 m for y and 9.81m/s² for g.

In the time t the package travels a horizontal distance x. The horizontal velocity of the package remains constant, since no force acts along the horizontal direction.
Therefore, the horizontal distance traveled by the package is given by,

If the package is released <u>678m</u> before the target, the package would reach the scientists working in Greenland.
Answer:
Fan Speed For Low Position vs Time Graph : The slope is curved and it increases as you go up . The points start off close but they spread out as the time increases.
Fan Speed For Medium Position vs Time Graph : The speed increases quicker than the graph for low speed. The graph is less curved than the one for low speed. Also, the points spread out faster than they did for low speed as the time increases.
Fan Speed For High Position vs Time Graph: The Graph has a smaller curve then the low and medium speed. Also , the points are the furthest apart. The slope is not as spaced out as it was for the rest of the speed graphs .
Explanation: I just finished the lab:)
Answer:
400 Hz
Explanation:
The frequency of a sound wave is found by the velocity/wavelength. Therefore, f = v/wavelength = (200 m/s)/(0.5 m) = 400 Hz
I hope this helps! :)
I will say increasing temperature but you dont have that option on your list, so I would take B. Increasing Concentration.
