Explain in terms of energy how dissipative forces such as friction reduce the amplitude of a harmonic oscillator. Also explain h
miss Akunina [59]

Answer:

There is the conservation of energy in a harmonic oscillator. As a result, the system amplitude will remain constant. The dissipative forces (i.e. friction) lead to loss of energy in different forms and the system amplitude is reduced due to the reduction in both kinetic and potential energies at the end of each oscillation.

The external forces acting on a driving mechanism must be accounted for at all times. In this case, there is a loss of energy because dissipative forces can be returned back to the system in the presence of the driving to account for the loss in energy.

Technician A says that failure analysis will assist the technician in determining whether it is more cost effective to replace r
Jobisdone [24]

Answer:

The correct option is;

Technician A

Explanation:

Here we note  failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.

However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.

a sponge and a bar of soap occupy the same amount of space, but the soap is much more dense than the sponge
Alex Ar [27]
Yes, that's correct.  That's a big part of the reason why
the soap floats in water and the sponge sinks in it.
