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:
direction, speed, and shape of a body
Explanation:
Answer:
B) the aluminum
Explanation:
The density of an object is proportional to its mass and inversely proportional to its volume. Since lead is denser than aluminum and both pieces have the same mass, then the aluminum piece has a larger volume and due to this, it will also displace more fluid. The buoyant force is proportional to the volume of the displaced fluid. Therefore, the buoyant force on aluminum is greater.
Explanation:
An elastic band is hung on a hook and a mass is hung on the lower end of the band. When the mass is pulled downward and then released, it vibrates vertically. The equation of motion is given by :
Where
s is in centimeters
t is in seconds
Velocity of the particle,
Acceleration of the particle,
Hence, this is the required solution.
