As a liquid is added to a beaker, the pressure exerted by the liquid on the bottom of the beaker ________.

Answers

Answer 1

Answer:

Answer:

Explanation:

Hydraulic systems is based on the principle of Pascals principle. Pascal's principle states that " Pressure applied to the to a fluid in a closed container (at rest) is transmitted equally to every point of the fluid and on the walls of the container".

Answer 2

Answer:

As a liquid is added to a beaker, the pressure exerted by the liquid on the bottom of the beaker increases compared to the liquid near at the tip of the beaker. Pressure increases as depth increases in any form of matter.

What is the half life of each of these radioactive isotopes?a radioactive isotope decreased to one-fourth its original amount in 18 months.

Answers

One fourth means (one half) of (one half) .

So the 18 months must be two half-lifes.

The half-life of this particular isotope is 9 months.

The half life would be 9 months long.

There is very high humidity in your area and a cold front moving in. What would be your forecast?

Answers

Answer:

Rain

Explanation:

A cold front is of a cooler mass of air, which replaces warmer mass of air of ground level and lies within a fairly sharp surface trough of low pressure.

As your area has very high humidity and a cold front is moving in, ultimately there will be continues rainfall and it will be there until cold front has moved away.

As in a cold front, warmer air mass is replaced by cold air mass, the cold air mass will combine with humidity resulting in lots and lots of rain.

You will end up having lots of rain until the cold front goes away.

Answers

Vi = 6 m/s
d = -2 m
a = - 9.81 m/s^2
t = ?
Formula
d = vi*t + 1/2 a t^2
- 2 = 6m/s *t - .5 * 9.81 * t^2
Put the - 2 on the right.
4.905 t^2 + 6 m/s t +2 = 0
a = -4.905 m/s^2
b = 6 m/s
c = 2 m
t = [- b +/- square root(b^2 - 4ac)]/(2a)
t = [ -6 +/- square root (6^2 - 4*(-4.905)*2)] / (- 4.905*2)
t = [-6 +/- 8.674) / - 9.81
t = -14.674/-9.81
t = 1.69 seconds.

Convert the term of g from m/s2 to cm/s2

Answers

To convert the acceleration from meters per second squared (m/s²) to centimeters per second squared (cm/s²), you can use the following conversion factor:

1 m = 100 cm

So, to convert from m/s² to cm/s², you need to square this factor because acceleration is in units of length per time squared:

(1 m/s²) = (100 cm/s²)

Therefore, 1 m/s² is equal to 100 cm/s².
