Which statements best describe x-rays? check all that apply. x-rays are electromagnetic waves. x-rays are longitudinal waves. x-
igor_vitrenko [27]

X ray is one of the electromagnetic waves.

As per Clark Maxwell's electromagnetic theory, all the electromagnetic waves move with the velocity of light i.e c= 3×10^8 m/s

In case of electromagnetic waves,the electric field and magnetic field are perpendicular to each other as well as perpendicular to the direction of propagation.The electromagnetic waves exhibit the property of polarisation. Hence they are transverse in nature.

Hence the best statements about X- ray will be-

1- X -rays are electromagnetic waves

2-X-rays are transverse transverse waves

3- X- rays travel at the speed of light.

If a weightlifter lifts a 286 kg mass 0.25 meters above his head, how much PEg does the mass have?
vazorg [7]

Answer:

Change in potential energy is 700.7 J.

Explanation:

Given:

Mass of the object is, m=286 kg

Height to which the object is raised above his head, h=0.25 m

Acceleration due to gravity is, g=9.8 m/s²

We know that for a mass m raised to a height h, the change in potential energy is given as:

\Delta PE=mgh, where, \Delta PE\rightarrow \textrm{Change in Potential Energy}

Now, plug in the given values and solve.

\Delta PE=286\times 9.8\times 0.25=700.7\textrm{ J}

Therefore, the change in the potential energy is 700.7 J.

What produced the helium now present in the sun’s atmosphere? In Jupiter’s atmosphere? In the sun’s core?
Paul [167]

Answer:

The helium contained in the Sun's atmosphere was produced by fusion of hydrogen to helium in the Sun's core. Since planets including the sun where all formed at the same time, Jupiter's atmosphere also contains Helium.

Explanation:

1) the helium in the suns atmosphere from the original helium and any helium the sun has produced from the nuclear fusion of hydrogen.

2) the helium present in Jupiter's atmosphere came from the helium in the matter that produced our solar system.

3) the helium found in the suns core comes only from the nuclear fusion of hydrogen
