if the volume of a gas contracted from 648 mL to 0.15L, what was its final pressure if it started at a pressure of 485 kpa
bija089 [108]

Answer:

2100 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

p₁V₁ = p₂V₂     Divide both sides of the equation by V₂

p₂ = p₁ × V₁/V₂  

p₁ = 485 kPa; V₁ =              648 mL  

p₂ = ?;            V₂ = 0.15 L = 150 mL      Calculate p₂

p₂ = 485 × 648/150

p₂ = 2100 kPa

pshichka [43]

The acceleration of Moby is 2 m/s²

<u>Explanation:</u>

Given:

Time, t = 5 seconds

Velocity, v = 10 m/s

Acceleration ,a = ?

We know:

Acceleration = \frac{velocity}{time}

On substituting the value we get:

a = \frac{10}{5} \\\\a = 2 m/s^2

Therefore, the acceleration of Moby is 2 m/s²
