It is very difficult to generate simple harmonic motion in a real world environment. Explain why this is the case.


I REALLY NEED HELP

Answers

Answer:

Simple harmonic motion is difficult to generate since real processes have irreversibilities, which are omitted in the physical model and represented by physical concept of damping.

Explanation:

It is very difficult to generate simple harmonic motion since real processes have irreversibilities that dissipy the mechanical energy within the system (e.g. air viscosity, friction), meaning that a permanent presence of an external load is needed to counteract such damping effects, in contrast with simple harmonic motion, where motion is self-sustained.

The 1.5kg ball is launched straight upward with an initial velocity of 7m/s. What is the maximum height it will reach?​

Answers

Answer:

h = 2.5 m

Explanation:

Given that,

Mass of a ball, m = 1.5 kg

Initial velocity of the ball, u = 7 m/s

We need to find the maximum height reached by the ball. Let it is be h. Using the conservation of energy to find it such that,

[tex]mgh=\dfrac{1}{2}mu^2\\\\h=\dfrac{u^2}{2g}[/tex]

Put all the values,

[tex]h=\dfrac{7^2}{2\times 9.8}\\\\=2.5\ m[/tex]

So, it will reach to a height of 2.5 m.

A 10 kg ball is falling on the planet Mars. Mars has an acceleration due to gravity of about 4 m/s/s. What is the force of gravity (or weight) of the ball on Mars?
A.6N
B.40N
C.0.4N
D.14N

Answers

Answer:

The force of gravity = 40 N

Explanation:

Given that,

The mass of a ball, m = 10 kg

The acceleration due to gravity on the surface of Mars, a = 4 m/s²

We need to find the force of gravity of the ball on Mars. The force of gravity on an object is given by :

F = mg

Substitute all the values,

F = 10 kg × 4 m/s²

F = 40 N

Hence, the correct option is (B).

In an electrical circuit, what happens to the current flowing through the wire if the initial voltage of 18 V is doubled, and the initial resistance of 35 Ohms is reduced by a factor of 4?

ANSWER QUICKLY PLEASE! ITS URGENT!

Answers

The current is increased by a factor of 8.

From 18/35 A. to 144/35 A.

The electric current changes from 0.514 ampere to 4.14 ampere, i.e, electric current flow in the circuit increases 8 times.

What is electric current?

A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.

Initial electric current flowing through the circuit = (18 volt ÷ 35 ohms)

= 0.514 ampere.

When the initial voltage of 18 V is doubled, and the initial resistance of 35 Ohms is reduced by a factor of 4, electric current flowing through the circuit will be = (2 × 18 volt )÷ (35 ohms÷4)

= 4.114 ampere.

Hence, electric current changes from 0.514 ampere to 4.14 ampere, i.e., electric current flow in the circuit increases 8 times.

A thin beam of light of wavelength 50 μm (in the infrared portion of the em spectrum) goes through

a thin slit and falls on a screen 3.00 m past the slit. You observe that the first completely dark fringes

occur on the screen at distances of ±8.24 mm from the central bright fringe, and that the central bright

fringe has an intensity of I0 at its center. (a) How wide is the slit? (b) What is the highest order fringe

this scenario is capable of producing? (c) What is the intensity of light at a point on the screen that is

one-quarter of the way from the central bright fringe to the first dark fringe?

Answers

Solution :

Given :

Wavelength of the thin beam of light, λ = 50 μm

Distance of the screen from the slit, D = 3.00 m

Width of the fringe, Δy = ±8.24 mm

Therefore, width of the slit is given by :

[tex]$d=\frac{n \lambda D}{\Delta y}$[/tex]

  [tex]$=\frac{2 \times 50 \times 10^{-9} \times 3}{2 \times 8.24 \times 10^{-3}}$[/tex]

  = 0.000018203 m

  = 0.0182 mm

  = 0.018 mm

The intensity of light is given by :

[tex]$I=I_0\left(\frac{\sin \beta /2}{\beta/ 2}\right)^2$[/tex]   , where [tex]$\beta=\frac{2 \pi D \sin \theta}{\lambda}$[/tex]

[tex]$I=I_0\left(\frac{\sin \frac{\pi d \sin \theta}{\lambda}}{\frac{\pi d \sin \theta}{\lambda}}\right)^2$[/tex]

[tex]$I=I_0\left(\frac{\sin \frac{\pi d y}{D\lambda}}{\frac{\pi d y}{D\lambda}}\right)^2$[/tex]

Now, [tex]$\frac{dy}{D \lambda} = \frac{8.24 \times 10^{-3}\times 0.018 \times 10^{-3}}{4 \times 50\times 10^{-9}\times 4}$[/tex]

               = 0.1854

               ≈ 0.18

[tex]$I=I_0\left(\frac{\sin 0.56}{0.56}\right)^2$[/tex]

  [tex]$=I_0 \times 0.81$[/tex]

  = 2  x0.81

  [tex]$= 1.62 \ W/m^2$[/tex]

A student does an experiment with a string vibrating at 20 hertz and observes the resonance pattern shown in the
diagram:
What is the speed of the wave on the string in Figure 24-3A?
4.0 m/s
8.0 m/s
20 m/s
100 m/s

Answers

Answer:

v = 8.0 m/s

Explanation:

The diagram clearly shows that the string is vibrating in the 5th harmonic. Hence, the length of string in terms o wavelength can be given as:

[tex]L = \frac{5}{2}\lambda\\\\\lambda = \frac{2}{5} L[/tex]

where,

λ = wavelength = ?

L = Length of string = 1 m

Therefore,

[tex]\lambda = \frac{2}{5}(1\ m)\\\\\lambda = 0.4\ m[/tex]

Now, the speed of the wave can be given by the following formula:

[tex]v = f\lambda\\[/tex]

where,

v = speed of wave =?

f = frequency of wave = 20 Hz

Therefore,

[tex]v = (20\ Hz)(0.4\ m)\\v = 8\ m/s\\[/tex]

Hence, the correct answer is:

v = 8.0 m/s

Photos A and B both show the same field of view containing a star-forming molecular cloud. One of the photos was taken in visible light and the other in infrared light. Which one is the visible-light photo, and how do you know?

Answers

Hello. You did not present the photos to which the question refers, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way.

Your question informs us that the photos are of a star-forming molecular cloud. The molecular cloud has dust, especially when the star is forming. In this case, we must keep in mind that in photos taken in visible light, the dust is able to appear, especially in space, where this dust would not reflect light, unlike the star in formation. In this case, we can conclude that in the case of the photo taken in visible light, we could see the molecular cloud as a dark spot, due to the dust. However, it would not be possible to view it in a photo taken with infrared light.

What is assimilation? Discuss the importance of social assimilation. Discuss immigration and some key challenges that an immigrant might face. What could be some benchmarks through which you can measure immigrant assimilation? What are some challenges that partners in an intercultural marriage may face? What can they do to avoid conflicts and resolve an argument or a disagreement?

Answers

Answer:

Assimilation refers to the process by which a person or ethnic group that constitutes a minority people imitates the culture of the majority population and, when the process is complete, completely abandons its own culture. Thus, the original cultural differences disappear and society becomes a monoculture. For example, immigrant groups or colonized indigenous peoples may abandon their culture, either spontaneously or after religious persecution and coercive measures, called assimilation policies.

A number of immigrant groups were assimilated into American society during the 19th century in what is usually described as a cultural melting pot or Americanization. In this case, the adaptation was not one-way, and largely spontaneous.

Four basic forces act on an airplane while in flight: lift, weight, drag, and thrust. These four forces and their directions are indicated below.

Answers

Complete question is;

Four basic forces act on an airplane while in flight: lift, weight, drag, and thrust. These four forces and their directions are indicated in the image attached.

If the thrust acting on an airplane is greater than the drag, then

A. The airplane will accelerate backward.

B. The lift will be greater then the weight.

C. The airplane will accelerate forward.

D. The weight will be greater than the lift

Answer:

C. The airplane will accelerate forward.

Explanation:

From the image attached, we can see that the thrust is the forward force responsible for pushing the plane forward while the drag is the one resisting this forward motion.

Thus, if the thrust is greater than the drag, it means the plane will accelerate forwards.

Thus, option C is correct.

explain why fish survive under water when the surface is already frozen​

Answers

Answer:

ice is a poor conductor of heat and less dense than water. During winter, ice floats and insulates the water under it. Below the frozen layer, the water remains in its liquid state and does not freeze. Also, oxygen is trapped beneath the layer of ice. This makes it possible for aquatic animals to survive during winter.

what do you mean by efficiency of a machine?​

Answers

Answer:

Efficiency in general means How well an object does with respect to its designated purpose for example a battery with Voltage of 10 volts won't exert 10 volts but slightly less due to internal resistance let's say 8V so efficiency will be 8/10 x100 = 80%

Same thing with a machine/engine If an engine is designed to produce 150 horsepower it won't give you the full energy due to part of the energy being dissipated in form of heat due to friction so let's say 145 hp is produced which is 96% efficiency
