A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm l

galben [10]

Answer:

Depth = 9 cm

Explanation:

First, calculate the volume of the cylindrical tin.

Mathematically, that would be the following:

$V = \pi * r^{2} * h$

Now, r = d/2 = 12/2 = 6 cm

h = 9 cm

Therefore, the volume will be:

V = 22/7 * 14 * 6^2 =1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

As we don't have the height of the tin so let's suppose it x, now it means that

l * b * h = 16 * 11 * x = 176x

Therefore, the depth would be:

176x = 1584

x = 1584 / 176 = <u>9 cm</u>

Which of the following is not an effect of complement activation? Select one: Interference with viral replication Increased phag

Nostrana [21]

Answer:

The correct answer is "Interference with viral replication".

Explanation:

The complement system is an essential part of the immune system that involves the activation of a series of proteins that act as a cascade and result in the development of inflammatory responses that help to fight infections. There are multiple effects of complement activation, however interference with viral replication is not one of them. The molecules that are able to interfere with viral replication are called interferons, and they synthesis and activation are not related with complement activation.
