If one oscillation has 5.8 times the energy of the second one of equal frequency and mass, 2.4:1 is the ratio of their amplitudes.
Oscillation is defined as the process of repeating fluctuations of a quantity or measure around its time equilibrium value. Oscillation can also be defined as the periodic fluctuation of matter between two values or about their average.
The definition of happiness is someone or something that makes you feel great joy or pleasure. An example of good luck is someone who wins the lottery. An example of happiness is a laughing baby. Besides making you feel better, positive emotions are good for your brain and body. It lowers stress hormones, relieves anxiety and depression, and strengthens the immune system. Feeling positive emotions every day has a huge impact on our well-being and health.

NoseIt - is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. It also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose there is the olfactory mucosa and the sinuses.
turbinate(or nasal concha)- is a long, narrow and curled bone shelf (shaped like an elongated sea-shell) which protrudes into the breathing passage of the nose. The turbinates divide the nasal airway into three groove-like air passages -and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible surface of cilia and climate controlling tissue.
Sinus- A sinus is a sack or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue.
Paranasal- Paranasal sinuses are air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face The paranasal sinuses are joined to the nasal cavity via small orifices called ostia.
Pharynx-The section of the alimentary canal that extends from the mouth and nasal cavities to the larynx, where it becomes continuous with the esophagus.
Larynx- Voice box
Epiglottis- The thin elastic cartilaginous structure located at the root of the tongue
Trachea-A thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs. Also called windpipe.
Bronchi-The two main brances of the trachea, leading directly to the lugns.
Bronchiole-The fine, thing-walled, tubular extensions of a bronchus.
Answer:
a.
b.
Explanation:
The computation is shown below:
data provided in the question
The initial angular velocity = 0 rev/s,
f = Final angular velocity = = 382000 rpm i.e = = 6,366.67
And time = t = 3.0s
Based on the above information
a. For angular acceleration of drill
b. For the number of revolutions
We simply applied the above formulas for determining each parts
Answer: bismuth and nitrogen, because they have the same number of valence electrons
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
The number of valence electrons in Bismuth and nitrogen are 5 and thus thus they will show similar chemical properties and thus belong to the same group.
The atomic masses of elements in a group will differ drastically.
The group number has got nothing to be the isolation year.
Thus bismuth and nitrogen belong to same group because they have the same number of valence electrons
Answer:
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A
Explanation:
the law of force show that focuses will always come in 2 or pairs and it also says that one body cannot exert a force on another without experiencing a force itself.
