Answer:
$0.43
Step-by-step explanation:
Preston adopted a cat from a rescue shelter
He needs to buy food for his new cat so he compared the price of cat litter at different stores
Preston gets the best deal at fluffy felines pet shop
They sell 20 pound jug litter for $8.60
Therefore the cost of the cat litter per pound can be calculated as follows
= 8.60/20
= 0.43
Hence the cost of the cat litter per pound is $0.43

Answer:
a). V
= 14.6208 litres : b). = 0.29844 Litres/sec
Step-by-step explanation:
a).
Step 1.
Volume when one half of rod is inserted = (50/2)*(2.2) = 55cm³
Step 2.
As we know that,
V
= (ρV
IΔT)
/ (ρL
)
where
= 290 - 4.2 = 285.8K
sepecififc heat of aluminum = 0.215 cal/g
density = 2.7 g/cm3
= (2.7)*(55)*(0.215)*(285.8) / (0.125)*(20900)*(1/4186)
V
= 14.6208 litres
b).
Step 1.
As we know that
P = kA(dT/dx) = 31*2.2*[(290-4.2)/25]
= 779.6624 W
Step 2.
Now, approximate boil rate of helium is:
P/ρL
= [(779.6624)*(10^3g/kg)] / [(0.125)*(20900)]
= 0.29844 Litres/sec
