Recall that the particles that make up matter are always moving. These particles have kinetic energy, the energy an object has due to its motion. The faster particles move, the more kinetic energy they have. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy. got it from this site http://www.ckrs.org/ckrs/About%20CKRS/Faculty%20Email%20and%20Web%20Pages/Mrs.%20Gail%20Grisi/GRADE%208%20PHYSICAL%20SCIENCE-Lessons%2CStudy%20Guides/%28Owls%29%20Reading%20essentials%20c.6-2%20Changes%20in%20State.pdf
Answer:
The force of the golf ball on Earth!
Explanation:
Action/Reaction Pairs work like this:
Earth on Golfball, Golfball on Earth.
Here's the magic formula: 1 'volt' = 1 joule per coulomb .
Everything else is just arithmetic.
So Voltage = (energy) / (charge)
Voltage = (0.5 J) / (1.6 x 10⁻¹⁹)
= 3.125 x 10⁻¹⁸ .
It's gotta be purple!!!!!!!!!!!!!!!
Answer:
Radio waves have a wavelength between and
While,
X rays have a wavelength between 1m and 10km.
=> It is one of the condition of diffraction that the obstacle (coming in the way) must be comparable with the size of the wavelength.
=> This shows, that radio waves have a wavelength which is comparable with the size of buildings and can really easily diffract through it
=> While, X-rays are big enough to diffract through the wall.
So, if an X-ray technician stands behind a wall during the use of her machine, she will remain safe.
