True. When speaking to someone, it’s important to make eye contact to show confidence in what you are saying. It’s also good to make eye contact when someone is talking to to you to make it clear that you are listening. It also makes you look more professional. Hope this helps :)!

true, it is very important to give the person talking your full attention. poor eye contact can show lack of interest or signs you aren’t paying attention.

Answer:

Velocity = 0.4762 m/s

Explanation:

Given the details for the simple harmonic motion from the question as:

Angular frequency, ω = 12 rad/s

Amplitude, A = 0.060 m

Displacement, y = 0.045 m

The initial Energy = U = (1/2) kA²

where A is the amplitude and k is the spring constant.

The final energy is potential and kinetic energy

K + U = (1/2) mv² + (1/2) kx²

where x is the displacement

m is the mass of the object

v is the speed of the object

Since energy is conservative. So, the final and initial energies are equal as:

(1/2) k A² = (1/2) m v² + (1/2) kx²

Using, ω² = k/m, we get:

Velocity:

$v=\omega\times \sqrt{[ A^2 - y^2 ]}$

$v=\omega\times \sqrt{[ {0.06}^2 - {0.045}^2 ]}$

<u>Velocity = 0.4762 m/s</u>
