vivado [14]

Answer: They have 30 containers of soup in all.

Step-by-step explanation:

Given: Total quantity of tomato basil soup= 6 gallons

Since 1 gallon = 4 quarters

Then , 6 gallons = 6 x 4 = 24 gallons

Since shop sells soup in 1-quart containers.

Now, total containers need to store 24 quarts soup= 24

They also had 8 containers leftover from yesterday.

So, total containers of soup they have =24+8 = 32

Hence, they have 30 containers of soup in all.

An aquarium 2 m long, 1 m wide, and 1 m deep is full of water. Find the work (in J) needed to pump half of the water out of the

Nitella [24]

Answer:

$W=2452.5 J$

Step-by-step explanation:

The work is define as the integral of the force times distance. So we have:

$W=\int^{a}_{b}Fxdx$

Now, we can write the force in terms of density.

$F=m*g=\rho Vg$

V is the volume (V=2*1*1=2 m³)

So the work will be:

$W=\int^{0.5}_{0} 2*1000*9.81*xdx=\int^{0.5}_{0} 2*1000*9.81*xdx=\int^{0.5}_{0}19620xdx=19620(\frac{x^{2}}{2})|^{0.5}_{0}$

The limit of integration is between 0 and 0.5 because we want to pump half of the water out of the aquarium.

$W=19620(\frac{x^{2}}{2})|^{0.5}_{0}=19620(\frac{0.5^{2}}{2})$

$W=2452.5 J$

I hope it helps you!
