14. Boyle’s Law states that when a sample of gas is compressed at a constant temperature, the pressure P of the gas is inversely

Ostrovityanka [42]

Answer:

dV/dt = 100 cm³/min

Step-by-step explanation:

Given

V = 728 cm³

P = 182 kPa

dP/dt = - 25 kPa/min

dV/dt = ?

If we apply the ideal gas equation

P*V = n*R*T

where n*R*T is constant

we have

d(P*V)/dt = d(n*R*T)/dt

⇒ d(P*V)/dt = 0

⇒ V*(dP/dt) + P*(dV/dt) = 0

⇒ dV/dt = - (V/P)*(dP/dt)

Plugging the known values we obtain

⇒ dV/dt = - (728 cm³/182 kPa)*(- 25 kPa/min)

⇒ dV/dt = 100 cm³/min

The diagram shows a right-angled triangle.

earnstyle [38]

Answer:

x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(x) = $\frac{9}{15}$

x = $\text{tan}^{-1}(\frac{9}{15} )$

x = $\text{tan}^{-1}(0.6)$

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°
