A uniform Capillary tube closed at one end Contain dry air trapped by a thread of mercury 8.5x10 m long when the tube was held horizontally, the length of the air Column 5.0X10^2 Wher it held verti cally with the closed end downward the length was 4.5x10^2m Determine the value of atmospheric pressure take g=10m/s, density of mercury (1.36×10^4kg/m)

Answers

Answer 1

Answer:

Answer:

To determine the value of atmospheric pressure, we can use the concept of hydrostatic pressure. By comparing the lengths of the air column in the capillary tube when held horizontally and vertically, we can equate the pressure difference to the difference in height of the mercury column. Using the given values and the density of mercury, we can calculate the atmospheric pressure.

The gravitational potential energy of an object Is always measured relative to the

Answers

The gravitational potential energy of an object Is always measured relative to the height of the object. It has the equation equal to mass PE = mgh where PE is the potential energy, m is the mass of the object, H is the height of the object and g is the acceleration due to gravity.

The gravitational potential of an object is always measured relative to reference level/another point

Further explanation

Energy is the ability to do work. Energy can change from one energy to another

Gravitational potential energy is the energy that an object has because of its position

The potential energy can be formulated:

Ep = m. g. h

E = potential energy of an object, joule

m = object mass, kg

g = gravity acceleration, m / s2

h = height of an object, m

The higher the object from the surface of the earth and the greater the mass, the greater the potential energy of the object. Earth's gravity also affects the potential energy of objects

Potential energy itself includes mechanical energy

Em = Ek + Ep

Em = mechanical energy

Ek = kinetic energy

Ep = potential energy

The amount of kinetic energy and potential energy of objects is always constant

Answer:

Reproducibility

Explanation:

The results of an experiment should be reproducible. By repeating the experiment several times, a confidence interval can be determined that will help establish that the results are real, and not an artefact

A wave will "break" because ________. a wave will "break" because ________. the sediment load of water is greater near the shore of random molecular motion in wave forms the density of water increases closer to shore the bottom interferes with its oscillatory motion the wind increases its speed near shorelines

Answers

A wave will "break" because the bottom interferes with its oscillatory motion. Breaking of waves may occur anywhere that the amplitude is sufficient, including in mid-ocean. When waves enter shallow water they break because the motion of water in lower part of the wave nearest the bottom is slowed by friction so that their oscillation is faster than its supporting portion at the bottom. Thus, the wave collapses forward and breaks.

Final answer:

A wave breaks due to the interference of the ocean floor with its oscillatory motion. As the wave nears the shore and the water gets shallower, the bottom of the wave slows down while the top continues its original speed, causing the wave to break.

Explanation:

A wave will 'break' or crash due to its interaction with the ocean floor as it approaches the shore. Waves follow an oscillatory motion, moving in an up-down pattern. When a wave gets closer to shore, the water becomes shallower which interferes with the oscillatory motion of the wave. The bottom of the wave slows down upon hitting the ocean floor while the top of the wave continues its original speed. This causes the wave to become steep and eventually break, forming the crashing wave front we often see on beaches.
