State Pascal's principle of transmission of pressure​
bulgar [2K]

Answer:

Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

A tennis ball is tossed upward with a speed of 3.0\,\dfrac{\text m}{\text s}3.0 s m ​ 3, point, 0, start fraction, start text, m
MrRa [10]

Answer:

The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).

Explanation:

Hi there!

The equation for the velocity of an object thrown upward is the following:

v = v0 + g · t

Where:

v = velocity of the ball.

v0 = initial velocity.

g = acceleration due to gravity (-9.8 m/s² considering the upward direction as positive).

t = time.

To find the velocity of the ball at t = 0.40 s, we have to replace "t" by 0.40 s in the equation:

v = v0 + g · t

v = 3.0 m/s - 9.8 m/s² · 0.40 s

v = -0.92 m/s

The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).

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.
