What is the pressure of the oxygen coming straight out of the O₂ flush valve (bypass)? a. 2000-2200 PSI b. 12-16 PSI c. 50-60 PSI d. 5-6 PSI"

The characteristics of electromagnetic waves typically represent as follows:

• There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values ​​at the same time and place.
• The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
• The shape of electromagnetic waves is transverse waves.
• It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
• The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
• The universal constant of the velocity of electromagnetic waves in a vacuum is
• The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
• Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

Further explanation

• Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
• From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
• Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
• As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
• Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
• Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

Answer: reflection

Refraction

Energy

Speed

Explanation:

Reflection results when em wave hits a plane surface and returns in the same angle it incident

Refraction is the change in velocity and direction of em wave as it crosses boundaries of different medium

The energy of em wave is evenly distributed in electric field and magnetic field

The speed of em wave is the same as 3×10^8

Answer;

-A triple beam balance

Explanation;

-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.

-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

Mass is measured using scales, a triple beam balance, or a mass meter.

What are scales used for?

Scales are commonly used for everyday measurements, where an object's weight is indirectly measured by the force it exerts on a spring or load cell.

A triple beam balance is a type of mechanical balance that uses a combination of sliding weights to determine mass.

Answer:how long it took you to get there and the distance between your house and her house

Explanation:

Answer:

349 m

Explanation:

Parameters given:

Mass of climber, m = 92.6 kg

Amount of food calories = 735

1 food calorie = 103 calories

735 food calories = 75705 calories

1 joule is equal to 0.239 calories. Therefore, 75705 calories will be 316749.72 joules.

Hence, this is the amount of work the climber must do work off the food he ate.

Work done is given as:

W = Force * distance

W = m * g * h

h = W/(m * g)

h = 316749.72/(92.6 * 9.8)

h = 349 m
