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:
I think that it might be cytoplasm
Explanation:
I got this from google
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
Answer:
11.9 moles of carbon-dioxide will produced.
Explanation:
Given moles of ethane = 5.95 mol
According to reaction 2 moles of ethane produces 4 moles of carbon-dioxide.
Then, 5.95 moles of ethane will produce:
of carbon-dioxide
11.9 moles of carbon-dioxide will produced.
False; Because when 2 substances are mixed another substance is created.
Answer:
well it is because of mainly what we call reaction the petrol are highly reactive with the flames
