A
An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.
Explanation:
Answer:
= 5.74W
=0.27 W
Explanation:
d= 2.6cm =>0.026m (for both the ceramic and the carpet )
Thermal conductivity of wool '
'= 
= 
= 0.04J/(sm °C)
Thermal conducticity of carpet '
' = 0.84 J/(sm °C)
Area 'A'= 
= 
= 77.2cm²=> 77.2 x 
m²
=33.0°C
=10.0°C
Average Power 
is determined by dividing amount of energy'Q' by time taken for the transfer't':
= Q/Δt
Due to conductivity, heat of flow rate will be P= dQ/dt
P=
= ![\frac{kA[T_{h}-T_{c} ]}{d}](https://tex.z-dn.net/?f=%5Cfrac%7BkA%5BT_%7Bh%7D-T_%7Bc%7D%20%5D%7D%7Bd%7D)
For CERAMIC:
=![\frac{k_{c} A[T_{h}-T_{c} ]}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Bk_%7Bc%7D%20A%5BT_%7Bh%7D-T_%7Bc%7D%20%5D%7D%7Bd%7D)
=> [0.84 x 77.2 x (33-10) ]/0.026
= 5.74W
For WOOL CARPET:
= ![\frac{k_{w} A[T_{h}-T_{c} ]}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Bk_%7Bw%7D%20A%5BT_%7Bh%7D-T_%7Bc%7D%20%5D%7D%7Bd%7D)
=> [0.04 x 77.2 x (33-10) ]/0.026
=0.27 W
Answer:
C. Distance 90 feet Displacement 0 feet
We can certainly draw water into our lungs, even though
our brain screams "Don't do that !".
But our lungs can only separate oxygen out of air, not out of
water. So if there's only water in our lungs, we pass out after
a short time because we're not getting any oxygen.
