If we assume also that the temperature of the air does not change, we can use Boyle's Law:
p₁V₁ = p₂V₂
Now, we know:
p₁ = 100kPa
V₂ = 100cm³ (the volume of the tyre)
V₁ = 120cm³ (becuse the air is contained inside the tyre AND the pump)
We can solve for p₂:
p₂ = (p₁V₁)/V₂
= (100×120)/100
= 120kPa
Therefore your answer is: 120kPa

Answer:
The percentage change in the hypothetical time is 10.53%
Explanation:
Percentage change in a quantity is given by;
* 100%
In this case, the quantity in question is time.
Therefore, percentage change in time =
* 100%
<em>where;</em>
Final time = 42minutes
Initial time = 38minutes
Substituting these values into the equation above gives;
=>
* 100%
=>
* 100%
=> 10.53%
<em>Hope this helps!</em>
