A damped harmonic oscillator driven by a harmonic external force maintains a steady oscillatory motion. Is energy lost to fricti

Answer:

Answered

Explanation:

When you are saying "damped harmonic oscillator" it basically implies the motion of the oscillator will be damped, so the oscillation should decay with time.

For example, consider a harmonic oscillator inside water. so here the motion of the oscillator will be damped due to the friction with the water.

So, yes energy will be lost to friction in the motion.

Ok, now for your case, you are giving an external harmonic force, that will keep the oscillator moving. Also, it maintains a steady oscillatory motion, implies that whatever damping is causing because of the friction, is exactly nullified by the external harmonic force.  Hence you get the steady oscillation.

A forces of 5 N accelerates an object. The object’s mass is 50 g. What is the acceleration of the object? (Formula: F=ma)
Harrizon [31]

Answer:

100 m / s^

F =ma from this divided F and ma by m to get acceleration

a = F / m

a = ?

F = 5 N

m = 50 g = 0. 0 5 kg ; if 1 kg = 1000g how much kg of 50 g by criss cross method we get 0.05 kg

so; 5N / 0. 05 kg = 5kg m / s^ / 0.05 kg

kg cancel by kg

the result is 100 m/ s^

A difference In density between gases creates buoyancy which is the ability of an object to float. 0°C helium has a density of .
rjkz [21]

Answer:

mass = 0.18 [kg]

Explanation:

This is a classic problem where we can apply the definition of density which is equal to mass over volume.

density = \frac{mass}{volume} \\\\where:\\volume = 1 [m^3]\\density = 0.18[kg/m^3]

mass = 0.18*1

mass = 0.18 [kg]

The particles ejected from the sun during a coronal mass ejection is called
ipn [44]

Answer:

Plasma

Explanation:

A Coronal Mass Ejection (CME) is an outburst of energy that occurs near the outer part of the sun's atmosphere which causes a production of plasma along with a magnetic field.

The outermost part of the sun's atmosphere is called the Solar Corona Although difficult to see, the corona can be seen during a total solar eclipse.

Plasma from CME are clouds of magnetized electrically charged particles which the solar wind causes to travel at a speed of 1.6 million km/hr.

inysia [295]

Answer:

Best explains Jamming

Explanation:

<em>The deliberate radiation of electromagnetic (EM) energy to degrade or neutralize the radio frequency long-haul supervisory control and data acquisition (SCADA) communications links, best explains what?</em>

Jamming is defined as the blocking or interference with authorized wireless communications. it's a problem  in personal area network wireless technologies. Jamming can occur inadvertently due to high levels of noise .

Jammers can send radio signals to interfere or disrupt communication flows by by decreasing the signal-to-noise ratio.They use radio frequency to interfere with communications by keeping it busy.
