How does a force pumb works​
ser-zykov [4K]

Answer:

A force pump can be used to raise water by a height of more than 10m, the maximum height allowed by atmospheric pressure using a common lift pump.

In a force pump, the upstroke of the piston draws water, through an inlet valve, into the cylinder. On the downstroke, the water is discharged, through an outlet valve, into the outlet pipe.

A sample contains 36 g of a radioactive isotope. How much radioactive isotope remains in the sample after 3 half-lives?
Gre4nikov [31]

Answer:

<u>Option "C":</u> "4.5 g"

Explanation:

N0 = 36 g, Let half-life is T.

t = 3 T, n is number of half lives = t / T = 3

<u>By using the decay law of radioactivity</u>

N / N0 = (1 / 2)^n

where

"N0" be the "initial amount"

"N" be the "amount left"

"n" be the "number of half-lives"

N / 36 = (1/2)^3

N / 36 = 1 / 8

N = 36 / 8 = 4.5 g

Tony gets stung by an ant. He applies baking soda, a weak base, to the site. What acid is Tony neutralizing with the baking soda
kumpel [21]
That's good !  I never heard of that before.  (Maybe because
I've never been stung by an ant.)

When an ant bites or stings, it injects a tiny amount of 'formic acid'
into your skin.  Soon, the formic acid itches, burns, and stings, and
after a while, a little piece of skin dies and falls off.  Some people
are seriously allergic to it, and it can make them really sick.

'Acids' and 'bases' are opposites, and one can neutralize (cancel out)
the other.  Tony is putting a weak 'base' on the sting, to neutralize the
formic acid that the ant left him as a little gift.
