What requirement must a force acting on a object satisfy in order for the object to undergo simple harmonic motion?

Physics

viktelen [127]3 years ago

Answer:

Simple harmonic motion is the movement of a body or an object to and from an equilibrium position. In a simple harmonic motion, the maximum displacement (also called the amplitude) on one side of the equilibrium position is equal to the maximum displacement.

The force acting on an object must satisfy Hooke's law for the object to undergo simple harmonic motion. The law states that the force must be directed always towards the equilibrium position and also directly proportional to the distance from this position.

Illusion [34]
In optics, you have to create a layer of coating that is approximately 1/4 of the light's wavelength. The working equation for this problem is:

d = λ₀/4n, 
where
λ₀ is the wavelength of the incident light
n is the refractive index of the coating

Substituting the values,

d = (650 nm)/4(1.39)
<em>d = 116.9 nm</em>

the formula relates the time, t, in seconds for a pendulum with the length, l, in feet, to make one full swing back and forth. w
Dovator [93]

This shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

Given the formula for calculating the length of the pendulum expressed as:

T= 2\pi\sqrt{\frac{L}{32} } where:

L is the length of the pendulum

T is the period of the pendulum

Given the following parameters:

Period T = 2.2 seconds

Substitute the given parameters into the formula will give;

2.2=2\pi \sqrt{\frac{L}{32} }\\ (\frac{22}{6.58} )^2 =\frac{L}{32} \\L=3.5032 \times 32\\L = 3.92.71 feet

So, this shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

A 0.954-kg toy car is powered by three D cells (4.50 V total) connected directly to a small DC motor. The car has an effective e
Natasha2012 [34]

Answer:

0.06 A

Explanation:

We have given mass =0.954 kg

velocity =1.27 m/sec

efficiency =0.361 the output kinetic energy of the motor KE=\frac{1}{2}mv^2=\frac{1}{2}\times 0.954\times 1.27^2=0.769\ J

Efficiency =0.361

so input to the motor = output/efficiency

so input to the motor = \frac{0.769}{0.361}=2.1301

we know that P=\frac{E}{T} where E is energy and T is time so P=\frac{2.1301}{7.88}=0.2703W

We know that power P=VI we have given V=4.5 VOLT

So current I=\frac{P}{V}=\frac{0.2703}{4.5}=0.06 A
