It would be purple. That is why it is the outside of the rainbow:)
Answer:9.8x10^(-3) w/m°C
Explanation:
Quantity of heat(Q)=14.1w
Distance(d)=2.44cm=2.44/100=0.0244m
Area(a)=1.88m^2
Temperature change(t)=18.6°C
thermal conductivity(k)=?
K=(Qxd) ➗ (a x t)
K=(14.1x0.0244) ➗ (1.88x18.6)
K=0.34404 ➗ 34.968
K=9.8x10^(-3) w/m°C
<span>When you in inhale, you move your diaphragm down increasing the volume of the cavity in your ribs (its called pleural cavity). This lowers the pressure inside your lungs. When the pressure in your lungs is less than the atmospheric pressure, air draws inwards. Ideal gas law: PV=nRT -> assume nRT are constant for our purposes. then we allow one system to be equal to the same system at different conditions, thus: P1V1=P2V2 (Boyles Law) assume P1=1 atm and V1=1 L (keeping the numbers simple to avoid confusion). when the V is increased (for example say doubled) V2=2 L, then: (1 atm)*(1 L)=P2*(2 L) -> P2=0.5 atm The pressure was decreased. Apply the same logic for exhalation.</span>
Acceleration = (change in speed)/(time for the change)
Change in speed = (end speed) - (start speed)
Change in speed = (10 m/s) - (20 m/s) = -10 m/s
Time for the change = 5.00 seconds
Acceleration = (-10 m/s) / (5 sec)
<em>Acceleration = -2 m/s²</em>
That's choice-A .
