A body of mass 1kg is made to oscillate on a spring of force constant 16 n/m calculate 1 the angular frequency 2 the frequency o
Scilla [17]

Explanation:

Given that,

Mass of a body, m = 1 kg

Force constant, k = 16 N/m

We need to find the angular frequency and the frequency of oscillation.

(a) The angular frequency of a body is given by :

\omega=\sqrt{\dfrac{k}{m}} \\\\=\omega=\sqrt{\dfrac{16}{1}} \\\\=4\ rad/s

(b) The frequency of oscillation is given by :

f=\dfrac{\omega}{2\pi}\\\\f=\dfrac{4}{2\pi}\\\\=\dfrac{2}{\pi}\ Hz

Hence, this is the required solution.

Doug is doing work. Without knowing exactly what he is doing, which can be said about the work he is doing?
WARRIOR [948]
<h3>Answer;</h3>

<em>Energy is transferred.</em>

<h3>Explanation;</h3>
  • Work is the force applied over a given distance, in other words work is the product of force and distance. That is; Work = force × distance.
  • Work is measured in Joules.
  • Energy on the other hand, is the ability to do work.
  • According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.
