Answer:

P.E.=29.4Nm

Explanation:

given data

m=1kg

h=3m

g=9.8m/s²

to find

gravitational potential energy=P.E.=?

solution

P.E.=mgh

PUTTING VALUES

P.E.=1kg×9.8m/s²×3m

P.E.=29.4Nm

What are the two applications of electron beam welding
Georgia [21]

First of all, there are not <u>just</u> two applications that are solely applicable to the electron beam welding process. There are MANY.

Please visit out website at the URL below and you can click the "View Application" button under each  listed Industry segment to view case studies of commonly EB welded applications.

Suppose an extraction with methylene chloride (d = 1.33 g/mL), also called dichloromethane, is performed with the desired compou
bekas [8.4K]

Answer:

Methylene chloride.

Explanation:

Two layers in the separation funnel are the aqueous phase and the organic phase. For solvents lighter than water (i.e., density < 1), the organic phase will rest on top in the separatory funnel, whereas solvents denser than water (density > 1) will sink to the bottom.

Since, methylene chloride is denser than Brine therefore, methylene chloreide sinks at the bottom while methylene chloride stays on top.

The simplest form of a traveling electromagnetic wave is a plane wave. For a wave traveling in the x direction whose electric fi
musickatia [10]

Answer:

amplitudes

Explanation:

In everyday physics we define the amplitude of a wave as the maximum (this can also be called the highest)displacement or distance moved by a point on a given vibrating body or wave as measured from its equilibrium position. The key idea in defining the amplitude of a wave motion is the idea of a 'maximum displacement from the position of equilibrium'.

Given the equations;

E= EoSin(kx - ωt)y

B= Bosin(kx- ωt)z

Both Eo and Bo refer to the maximum displacement of the electric and magnetic field components of the electromagnetic wave. This maximum displacement is known as the amplitude of the electric and magnetic components of the electromagnetic wave.

Answer:

TRUE OR FALSE : ) IT'S TRUE

EXPLAIN:

Radiation

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Radiant energy spreads out from its source in all directions. ... GAMMA RAYS have more energy than XRAYS, Radio waves, microwaves and ultraviolet waves all have longer wavelengths than visible light. Both X rays and gamma rays have higher frequencies than ultraviolet rays.

stepan [7]

Answer:

L'ozone est produit à partir du dioxygène, composé de deux atomes d'oxygène(O2). Aux altitudes supérieures à 30 km, le rayonnement solaire possède encore une énergie suffisante pour casser une partie des molécules de dioxygène et libérer les atomes
