Answer:
V₂ = 2 L
Explanation:
given,
P₁ = 203 kPa
V₁ = 0.5 L
Now, volume is expanded
P₂ = 50.8 kPa
V₂ = ?
Using Boyle's law
P₁V₁ = P₂ V₂
inserting all the values
V₂ = 2 L
Hence, new volume of air in the pump is equal to 2 L.
Answer:
Considering the lack of information, this is the best I can do.
The average velocity can be calculated via .
If there is acceleration instead of V or V not given, use the first kinematic equation:
Hope it helps :) and provide more complete information and I can answer better
<u>Answer:</u>
Force = 20N
acceleration (a) = 1.5 m/s²
Mass of object (m) = ?
<u>From Newtons II law</u>
<em> F = m. a N</em>
m = F/a
m = 20/1.5
<em> m = 13.34 Kg</em>
<em>Mass of an object is 13.34 Kg</em>
