The diagram you posted above represents a standing wave on a string. The maximum constructive interference occurs at the antinodes B and D. The correct answer choice is number 3, antinodes B & D. Be careful when choosing as the above choices are not in correct order. Instead of 1,2,3,4, the choices above are 1,3,2, and 4.
Answer:
<h2>27.65 sec</h2>
Explanation:
The Cylinder rotates about it's axis, thus there exists a Centrifugal force on a object which is on the inner surface of the cylinder. This is one of the many ideas that are currently being used in space habitation.
So, Centrifugal force acts like Normal gravity when both have equal magnitude.
is the mass of astronaut, is the Earth's gravity, is the velocity of astronaut, is the Time period of rotation.
∴ It takes 27.65 sec for rotation of cylinder, if it is to provide normal gravity for astronauts.
Less than 7, Ph of 7 is neutral Acid Rain would be between 4 and 0.
Answer:
The answer is:-
Explanation:
An electron emitted from an atom by enteraction with an photon, especially an eclectron emitted from a solid surface by the action of light.
One - Cosmic "egg"
Two - Expansion
-no explosion
-expansion causes cooling
Three - Subatomic particles form quarks/electrons
Four - More cooling
Protons and neutrons form
Five - Formation of atoms
Six - Gravity causes atoms to form clouds of gas which forms stars
Seven - Stars group together to form galaxies
hope that helped somehow...
