Where are the answer choices?
Since the bell weighs 190 N and is 45 m high, the bell’s potential energy is 8550 J
To answer the question, we need to know what potential energy is.
<h3>What is potential energy?</h3>
This is energy due to position. It is given by PE = mgh where
- m = mass,
- g = acceleration due to gravity and
- h = height of object.
Also, W = mg = weight of object.
So, PE = Wh
<h3>
The bell's potential energy</h3>
Now, given that the bells weight 190 N and is 45 m high,
So, PE = Wh
= 190 N × 45 m
= 8550 Nm
= 8550 J
So, the bell’s potential energy is 8550 J

Answer:
Alien Species
Explanation:
This is known as an alien species threat to biodiversity as there is a newly added species taking over another. Mongooses were intended to control the snake population but it got out of control and is now threatening snake life in Hawaii.
