A 2.0-kg object is attached to a spring (k = 55.6 N/m) that hangs vertically from the ceiling. The object is displaced 0.045 m v

ertically. When the object is released, the system undergoes simple harmonic motion. What is the magnitude of the maximum acceleration of the object?

Answer:

Maximum acceleration will be 1.251m/sec^2

Explanation:

We have given mass of the object m = 2 kg

Spring constant k = 55.6 N/m

Amplitude is given as A = 0.045 m

We know that maximum acceleration in SHM is given by

Maximum acceleration =A\omega ^2

We know that \omega ^2=\frac{k}{m}=\frac{55.6}{2}=27.8

So maximum acceleration = 27.8\times 0.045=1.251m/sec^2

Answer:

34.78 m/s^2

Explanation:

mass of object, m = 2 kg

Spring constant, K = 55.6 N/m

Displacement, A = 0.045 m

Angular velocity

\omega =\sqrt{\frac{k}{m}}

\omega =\sqrt{\frac{55.6}{2}}

ω = 27.8 rad/s

The value of maximum acceleration is given by

a = ω² A

a = 27.8 x 27.8 x 0.045 = 34.78 m/s^2

Thus, the maximum acceleration is 34.78 m/s^2.

Is a quantum of light or a single packet/particle of light at a given wavelength.
Yanka [14]

Photon is a quantum of light or a single packet/particle of light at a given wavelength.

Answer: Option B

<u>Explanation: </u>

It is known that light has dual nature of wave as well as particles. Light waves can behave in wave nature as well as in particle nature depending upon the situation. So the light waves are assumed in different views to easily understand the nature of light waves.

There are several models proposed to simplify the nature of light. Among the several assumptions, one of the most prominent observations are that light waves or quantum of light are termed as photons which are made up of single packet/particles of light in a given wavelength.
