Can an astronaut hear a mile away when helmet mic is broke?
Because sound needs particles to travel through ; when a sound from inside one helmet is made, the particles vibrate the surrounding particles therefore vibrating the other astronauts helmet particles ( as they are touching) allowing him to hear the sound.
Some regions along the plane of the Milky Way appear dark because?
stars in that region are hidden by dark dust particles.
Why do you sneeze if there are ashes?
Because some of the ash particles get in your nose, and irritate the nerves in your nose, that's the bodies way of getting stuff out of your nose.
How is the relationship between protons and alpha particles similar to the relationship between beta particles and electrons?
An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
Why can't the astronauts use regular salt and pepper in space?
Because the small particles will float around and cause problems and corrosion on the electronics and other mechanisms.
The ability to become uniformly distributed describes what type of matter?
The type of matter is a gas, because the particles in a gas are spread or distributed far apart
Is Iodine and water a heterogeneous or homogeneous mixture?
A heterogeneous mixture is a mixture of two or more substances that are not uniformly distributed. The iodine and water in the question are not homogeneous because they are not uniformly distributed.
Why doesnt air temperature change uniformly with altitude?
Altitude doesn't change uniformly because the four main layers of the atmosphere have different temperature gradients, creating the thermal structure of the atmosphere.
What makes the army uniform a uniform?
Because it's worn uniformly by all personnel in the Army.
Why is a copper ore heterogeneous?
Because an ore contain many components which are not uniformly distributed in the mass.
Why does radiation not require other particles?
Because radiation is particles.
Can synchrotron accelerate charged particles to high speeds because it compensates for the increase in the particles because of the increase in the particles energy?
Yes, a synchrotron can accelerate charged particles to high speeds because of this compensation.
What is a mixture that looks the same throughout because it's components are uniformly mixed together?
This is called a homogenous mixture
What do mixtures have in them that makes particles visible?
nothing, the particles are visible because the particles are in the mixture. The substances being visble and identifiable in a mixture is because that mixture is heterogenous.
Why are electrons atomic particles?
Because they are particles, and they are part of the atomic structure.
Why particles vibrates?
Particles vibrate because of heat being present
Is a energy drink a homogeneous or heterogeneous?
Heterogeneous, because it contains liquid and gas (carbonation), so it can't be uniformly mixed.
