Amass-spring system oscillates with an amplitude of 4.60 cm. if the spring constant is 234 n/m and the mass is 524 g, determine the mechanical energy of the system.

Mechanical energy, U = 0.247 Joules

Explanation:

Given that,

Spring constant of the spring, k = 234 N/m

Mass, m = 524 g = 0.524 kg

Amplitude, A = 4.6 cm = 0.046 m

To find,

The mechanical energy of the system.

Solution,

We know that the sum of kinetic energy and the potential energy is equal to its mechanical energy. In mass-spring system, it is given by :

U = 0.247 Joules

So, the mechanical energy of the system is 0.247 Joules.

d) physical means can be used to separate the components of air.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
