the answer would be B) displacement of particles is perpendicular to the direction of wave motion
Answer:
Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.
Explanation:
The correct answer is option 2. Systems, by
nature, tend to undergo changes toward higher entropy and lower energy since
this is the state where they are most stable. Entropy is the degree of
disorderliness of a substance. Systems tend to go to higher disorder since
systems always tend to change which can be linked to disorder and is
inevitable.
Answer:
The frequency of the photon is .
Explanation:
Given that,
Energy
We need to calculate the energy
Using relation of energy
Where, = energy spacing
Put the value of h into the formula
Hence, The frequency of the photon is .
Student 1 will win the race.
More kinetic energy= faster
