Answer:
The answer is
<h3>6000 N/m² or 6000 Pa</h3>
Explanation:
The pressure exerted by an object given the force of the object and the area can be found by using the formula

where
P is the pressure
f is the force
a is the area
From the question
f = 2400 N
a = 0.4 m²
So we have

We have the final answer as
<h3>6000 N/m² or 6000 Pa</h3>
Hope this helps you
I think it's less, more, more. correct me if i'm wrong
Answer:
c) more particles collide with the walls of the container
Explanation:
More moles means more particles. If the volume remains the same, the collisions of more particles with the container walls cause the pressure to increase.
Answer:
Endothermic
Explanation:
This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.
Answer:
The answer to your question is: [H+] = 0.0016
Explanation:
Data
pH = 2.8
[H+] of the solution = ?
Formula
pH = -log [H+]
process
2.8 = -log [H+] then we get antilog
antilog (-2.8 ) = [H+]
[H+] = 0.0016
