The pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an ideal gas are related by t

stich3 [128]

Answer:

$\dfrac{dV}{dt} = -0.466 m^3/s$

Explanation:

given,

P (in kilo pascals), volume V (in liters), temperature T (in kelvins)

P V = 8.31 T

Rate of increase the temperature = 0.1 K/s

temperature = 285 K

Pressure = 18 kPa

increasing at the rate of 0.07 k Pa/s

Rate at which volume is changing = ?

$V = 8.31 \dfrac{T}{P}$

$\dfrac{dV}{dt} = 8.31 \dfrac{P\dfrac{dT}{dt}-T\dfrac{dP}{dt}}{P^2}$

$\dfrac{dV}{dt} = 8.31 \dfrac{18 \times 0.1-285\times 0.07}{18^2}$

$\dfrac{dV}{dt} = 8.31 \dfrac{-18.15}{324}$

$\dfrac{dV}{dt} = -0.466 m^3/s$

A thin, uniform, metal bar, 3.00 m long and weighing 90.0 N , is hanging vertically from the ceiling by a frictionless pivot. Su

liraira [26]

Answer:

$\omega_f=-2.6rad/s$

Since the bar cannot translate, linear momentum is not conserved

Explanation:

By conservation of the angular momentum:

Lo = Lf

$I_B*\omega_o+I_b*(V_o/d)=I_B*\omega_f+I_b*(V_f/d)$

where

$I_B =1/3*M_B*L^2$

$I_b=m_b*d^2$

$M_B=90/g=9kg$ ; $m_b=3kg$ ; d=1.6m; L=3m; $V_o=-10m/s$ ; $V_f=5m/s$ ; $\omega_o=0 rad/s$

Solving for $\omega_f$ :

$\omega_f=m_b*d/I_B*(V_o-V_f)$

Replacing the values we get:

$\omega_f=-2.6rad/s$

Since the bar can only rotate (it canno translate), only angular momentum is conserved.

If the baseball and the plastic ball were moving at the same speed which ball would hit a bat harder

Natali [406]

The baseball because it has a greater mass and would go farther because it don't have holes for the air to go through and slow it down
