A waste treatment pond is 50 m long and 25 m wide, and has an average depth of 2 m. The density of the waste is 75.3lbm/ft^3 .Ca
umka21 [38]

Answer:

W = 6.65 \cdot 10^{6} lbf

Explanation:

To find the weight (W) of the pond contents first we need to use the following equation:

W = m\cdot g   (1)

Where m the mass and g is the gravity  

Also, we have that the mass is:

m = \rho*V  (2)    

Where ρ is the density and V the volume

We cand calculate the volume as follows:

V = L*w*d   (3)

Where L is the length, w is the wide and d is the depth  

By entering equation (2) and (3) into (1) we have:

W = \rho*L*w*d*g

W = 75.3 lbm/ft^{3}*50 m*25 m*2 m*9.81 m/s^{2}  

W = 75.3 lbm/ft^{3}*\frac{(1 ft)^{3}}{(0.3048 m)^{3}}*\frac{0.454 kg}{1 lbm}*50 m*25 m*2 m*9.81 m/s^{2} = 2.96 \cdot 10^{7} N}*\frac{0.2248 lbf}{1 N} = 6.65\cdot 10^{6} lbf              

Therefore, the weight of the pond is 6.65x10⁶ lbf.

I hope it helps you!

Answer asap with at least 3 or more sentences!
mixas84 [53]

Answer:

no.

Explanation:

The reason this has

never happened is due to the source of magnetic fields:  moving electric

charges.  When electric charges (e.g. electrons) move in circles, they

produce a magnetic field.  In a piece of iron, it is very easy to line up

these circles, getting all the little magnets to work together as one big

magnet.

For each of these circles, one side is the north pole and one side is the

south pole.  Since each circle has two sides, each circle has a north and a

south pole.  Even the smallest possible magnets (spinning electrons) have a

north and a south pole.
