If the wavelength is doubled, frequency is halved. The wavelength and frequency of a wave are inversely proportional to each other and both are directly proportional to the velocity of the wave.
Answer:
The applied force is greater than the frictional force.
Explanation:
the chair moves at <u>a constant speed</u><u> </u><u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>not</u><u> </u><u>A</u><u> </u><u>or</u><u> </u><u>C</u><u>.</u>
if there is no friction then the chair <u>would accelerate and it would not be at a constant speed</u><u>.</u>
hence, the only possible answer is B.
For a solid to change its state of matter into liquid, energy is applied or heat is being used. With a solid, particles are very compacted and still, with a liquid they are not as compacted but can still take a defined shape.
Similar chemical behavior. All the members of a group of elements have the same number of valence electrons and similar chemical properties.
