Applying Concepts Your friend is playing a song on a piano. Whenever your friend hits a certain key, the lamp on top of the piano rattles. Explain why the lamp rattles.

Answers

Answer 1

Answer:

The lamp rattles because close resonant frequency.

Explanation:

The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.

Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.

Thereforee, the lamp rattles because close resonant frequency.

C. 3rd Law

Answers

Answer: C (3rd law)

Explanation:

Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.

Will pigs ever fly?
Support your answer with suitable examples. ​

Answers

Answer:

NO

Explanation:

the pigs will never be able to fly as the birds have:

wings – these enable the force of lift.

lightweight, smooth feathers – this reduces the forces of weight and drag

streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)

light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight

Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.

Answer:yes they might

Explanation:

Birds are able to breed with pigs and pigs might get wings
