How Do Manometers Work? steps by steps

Physics

blondinia [14]4 years ago

Explanation:

A manometer is a device that measures air pressure using a container with a "U"-shaped tube open at one or both ends. In a closed manometer, a sample of gas is introduced into one end, which is then capped. ... This pressure represents the positive or negative difference between the gas pressure and atmospheric pressure

Answer:

<h2>I hope this helps </h2>

  1. In the manometer, one end connects to a gas-tight seal to test the pressure source.

2. In addition, the other end of the tube is left open to the atmosphere and it will be subjected to the pressure of approximately 1 atmosphere (atm).

3. Besides, the test pressure is greater than the pressure of 1 atm (atmosphere) the liquid in the column will be forced down by the pressure.

4. Furthermore, it will cause the liquid of the reference column to rise by an equal amount.

Law Incorporation [45]
Drag is usually ignored because its effect on the horizontal velocity is usually negligible due to the short time of flight.

An object's surface area and geometry, along with the object's surrounding wind speed will affect the drag force.

In most cases, drag force will cause the object to land horizontally closer to the predicted landing point as drag is a resistive force.

victus00 [196]

In the absence of a net force, an object can be at rest or in motion with a constant velocity.

<h3>What is Newton's first law of motion?</h3>

Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path <u>unless acted upon</u> by an external force.

This law is also called the law of inertia because it depends on mass.

F(net) = ma

when, F(net) = 0, acceleration will be zero and velocity will be constant.

Thus, in the absence of a net force, an object can be at rest or in motion with a constant velocity.

During the spin cycle of your clothes washer, the tub rotates at a steady angular velocity of 31.7 rad/s. Find the angular displ
Crank

Answer:

\Delta \theta = 3116.11\,rad and \Delta \theta = 495.944\,rev

Explanation:

The tub rotates at constant speed and the kinematic formula to describe the change in angular displacement (\Delta \theta), measured in radians, is:

\Delta \theta = \omega \cdot \Delta t

Where:

\omega - Steady angular speed, measured in radians per second.

\Delta t - Time, measured in seconds.

If \omega = 31.7\,\frac{rad}{s} and \Delta t = 98.3\,s, then:

\Delta \theta = \left(31.7\,\frac{rad}{s} \right)\cdot (98.3\,s)

\Delta \theta = 3116.11\,rad

The change in angular displacement, measured in revolutions, is given by the following expression:

\Delta \theta = (3116.11\,rad)\cdot \left(\frac{1}{2\pi} \frac{rev}{rad} \right)

\Delta \theta = 495.944\,rev

What area of earth contains semi-solid rock and lava?
ioda
Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.

Hope this helped! :)
