The question is not complete, here is the complete question
<em>"Beatrice and the Elevator Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is traveling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator.</em>
<em>1. . What question is Beatrice trying to answer?</em>
<em>2. What is one variable Beatrice could change in her investigation? What might she figure out if this
</em>
<em> variable was changed"</em>
1. Beatrice is trying to observe the influence of the elevator movement on her weight, Hence the question is<em> "will the elevator movement cause her weight to change"</em>
therefore moving upward the reading on the scale will increase
Reading=mg+ma
downward
Reading will reduce
Reading=mg-ma
2. The independent variable is the acceleration due to gravity g=9.81m/s^2
while the dependent variables are
i. The elevators acceleration
ii. Beatrice's mass

Had to look for the options and here is my answer.
Given the situation that a poison is consumed and this prevented the acetylcholine release, the one that would most likely occur at a myoneural junction is that "sodium and potassium gates on the motor end plate will not open". Hope this helps.
Answer:
735 J
Explanation:
From the question given above, the following data were obtained:
Weight (W) = 49 N
Height (h) = 15 m
Potential energy =?
Potential energy is simply defined as the product of weight of the object and height to which the object is raised. Mathematically, it is expressed as:
Potential energy = weight × height
With the above formula, we can obtain the potential energy of the coconut as follow:
Weight (W) = 49 N
Height (h) = 15 m
Potential energy =?
Potential energy = weight × height
Potential energy = 49 × 15
Potential energy = 735 J
Thus, the potential energy of the coconut is 735 J
