Answer:

It's not plugged in. A fuse is blown. Oxygen is no longer present because we killed all our trees. The pressure gauge is broken and all your Oxygen is gas because the gauge says you are at 30 atmospheres when you are actually at 1.5. The cooler is outdated and requires CFCs, which are now illegal. The cooler is too small to reduce the temperature of the quantity of oxygen you wish to liquefy. Your liquid oxygen machine is actually a liquid helium machine. The company that sold you your liquid oxygen machine was scamming you and now it looks really complex but in fact if you break it open with a sledgehammer, you will see that the inside is made completely of useless nonbouyant rubber duckies. Operator error.

Explanation:

All are entirely possible and would cause a liquid oxygen machine to be defected.

The infrared spectrum above represents the absorption of certain wavelengths of radiation by molecules of CO2. Which of the foll
valkas [14]

Answer:

Carbon Dioxide is an Infrared Radiation Absorber. The (CO2) molecules also emits the absorbed infrared (IR) radiation energy. The photon energy from the infrared radiation causes the CO2 molecule to vibrate. Only some of its vibrational modes absorb infrared radiation

Explanation:

Its linear structure is considered when working with the formula to calculate the number of molecular vibrational modes. It has 3n - 4 vibrational modes, where n is the number of atoms in a compound of CO2

With 3 atoms, CO2 has

3n−5=4 types or patterns of vibration

1. The symmetric stretch

2. The asymmetric stretch

3. The bend

The symmetric stretch vibrational mode is ir-inactive.

The asymmetric stretch is ir-active as it results in changes in dipole moment

The bend is ir-active as well as it results in a change in dipole moment too.

<h2>Plasma is most likely inflence by - Option C</h2>

This plasma is most likely influenced by magnetic and electric fields. The massive positively charged ions which are influenced the lighter electrons than replace the ions to keep charge impartiality.

Therefore electric field influence the plasma. The movement of charged particles identical to a magnetic field line is not influenced. Plasma contains charged particles which are positive nuclei and negative electrons which can be molded and restricted by magnetic forces.

Alike iron filings in the closeness of a magnet, bits in the plasma will ensue magnetic field lines.
