Why must the bottom of a food pyramid be wider then the top?
the reason is because its more important food ( health wise ) than the top
Why are penguins wider at the bottom than at top?
Natural Hydrodynamics. Same as in all birds nature has crafted them in a wedge shape for better movement through water or air.
Is denominator on the top or bottom?
Numerator on top; denominator on the bottom.
What is the rule in comparing a set of fractions?
the top adds what the bottom adds. the top subtracts what the bottom subtracts. the top divides what the bottom divides. the top multiplies what the bottom multiplies.
Is a denominator at the top or the bottom?
bottom
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Is the Hoover Dam the same thickness at the top as the bottom?
no, its thicker at the bottom
Why do dams need to be thicker on the bottom and thiner at the top?
because the water pressure on the damn is much higher on the bottom of it than the top.
Why are dams over rivers are made broader at bottom than at the top?
The pressure of the water (the weight) is greater at the bottom, due to the depth of the water. As the pressure is less near the top, the top of the dam wall doesn't need to be as thick as the bottom of the dam wall.
What is the width of the Nurek Dam?
The Nurek Dam in Tajikistan is 714 meters at the top and 1,420 meters are the bottom. It is an earthen dam across the Vakhsh River.
If the bottom of the population pyramid is wider than the top, what does that mean?
there are mums down there
Why is the base of a dam thinner then the wall?
The pressure against the dam wall increases at the lower levels than nearer the surface. So I expect the foot of the dam wall to be thicker at the bottom than at the top.
Why dams must be constructed so that they are much thicker at the bottom than the top?
Because the water pressure at the bottom of the dam is much more than the top.
Is pressure lower at the bottom of a dam?
Density of water per unit volume ie. g/cm3 * depth of water (cm). Answer will be in g/sq cm. Density of water is approximately 1g / cm3 therefore pressure at the bottom of a dam wall with 1m of water = 0.1kg / sq cm. Note: this is only valid at the bottom of the wall, half way up the 1m of water the pressure would be 0.05kg / sq cm. At the very surface of the water, there would be no pressure. Thats why a finger in a dyke (dike) can hold back the North Sea!

Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
When you measure a pie pan do you measure at the top where it's wider or at the bottom?
you measure at the top. Typically, pie pans are 8 or 9 inches.
