Answer:
Answer:
Option B
Explanation:
Option B talks about how the frequency of the wave increases the shorter it's wavelengths
Answer:
61.0168 g/mol Explanation:
This is mainly because the
wavelength of a moving soccer ball is extremely small so it is not detectable
to the naked eye. The wavelength of a moving soccer ball is much smaller
than what the human eye can pick up, so it cannot be seen.
Answer:
Potential Energy is given as:
P.E = mgh
which means P.E is directly proportional to height 'h'.
Kinetic Energy is given as:
K.E = (1/2)mv²
which means K.E is directly proportional to velocity 'v²'.
Total Energy of Pendulum = K.E + P.E
1. The pendulum has the most potential energy at extreme position because the height is maximum at the extreme position.
2. The pendulum has the least kinetic energy at extreme position because the velocity is zero at extreme position.
3. The pendulum has most kinetic energy at the mean position because the velocity is maximum at this point.
4. The pendulum has the least potential energy at the mean position because the height is minimum.
A rule to remember: The point where K.E is maximum, P.E is zero at this point and vice versa.
