When all of the linear dimensions are doubled . . .
-- the perimeter is also doubled
-- the area is multiplied by 22 = 4.
The volume increases by 8 times (23). doubling is 2, so its 2 to the power of 3. Leigh
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
You would also double the perimeter.
Since the perimeter is a linear measure it is also doubled.
If the side is 11 then the perimeter is 44.The altitude is irrelevant. It can be anything less than 11, with no effect on the perimeter.
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
The volume increases by 8 times (23). doubling is 2, so its 2 to the power of 3. Leigh
Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =? (2l)(2w)Rectangle Area =? 4lw4(Rectangle Area) = 4lwThus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.
the velocity is decreased
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
doubles
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
You would also double the perimeter.
pressure will be halved
Since the perimeter is a linear measure it is also doubled.
It is define as twice the maximum symetrical short circuit current.
If the side is 11 then the perimeter is 44.The altitude is irrelevant. It can be anything less than 11, with no effect on the perimeter.
