show that for a clósed organ pipe only odd harmonics are present wheras for an open organ pipe all the harmonics are present​

Answers

Answer:

For a closed organ pipe, the point at the closed end is always a node, 'N' while the open end is always an antinode, 'A'

Therefore, for a closed organ pipe, we only have;

NA = N↔A = First harmonics = f₁

NANA = NA↔AN↔ NA = Third harmonics, = f₃ = 3·f₁

NANANA = NA↔AN ↔ NA ↔ AN ↔ NA = f₅ = 5·f₁

It can also be shown that for a closed organ pipe, only f₇, f₉, f₁₁, ... are present

Therefore, a closed organ pipe has only odd harmonics present

For an open organ pipe, we have;

ANA = First harmonics = f₁

ANANA = ANA ↔ ANA = Second harmonics = f₂ = 2·f₁

ANANANA = ANA ↔ ANA ↔ ANA = Third harmonics = f₃ = 3·f₁

Similar relationship exist for f₄, f₅, f₆...

Therefore, for an open organ pipe, all harmonics, (multiples of the fundamental, f₁) are present

Explanation:

A boy moves around a square path of side 15m. He completes 1 round in 40 sec. 1 Calculate the displacement of the boy at the end of 2min 20sec.





Plsss answer fast!

Answers

Answer:

Explanation:

2 min 20 sec = 140 sec .

In 40 sec  one round

In 140 sec 140 / 40 round = 3.5 round .

That means the boy will be positioned at the diametrically opposite corner of the square path .

side of square path = 15 m

length of diameter = 15√2

= 21.21 m

Displacement of boy is 21.21 m .

An astronaut has a mass of 70kg.
The force of gravity on the Moon is approximately 1.5N/kg.
Calculate the weight of the astronaut when they are on the Moon.

Weight = .............................................................. N

Answers

Answer:

Weight = 105 Newton

Explanation:

Given the following data;

Mass = 70kg

Force of gravity = 1.5N/kg

To find the weight;

Weight = mass * force of gravity

Substituting into the equation, we have;

Weight = 70 * 1.5

Weight = 105 Newton

Therefore, the weight of the astronaut when they are on the Moon is 105 Newton.

Pred p = mxv> (1 kg) x (+5) = +5 kg m/s

Pblue: P = mxv

(1 kg) x (0) = 0 kg m/s

Answers

Answer:

Momentum of red car = 5kgm/s

Momentum of blue car = 0kgm/s

Explanation:

Momentum = mass × velocity

For the red car

Mass = 1kg

Velocity = 5m/s

Momentum of the red car = 1kg × 5m/s

Momentum of the red car = 5kgm/s

For the blue car.

Mass = 1kg

Velocity = 0m/s(shows that the blue car is stationery)

Momentum = 1kg ×0m/s

Momentum of the blue car = 0kgm/s

A baseball player slows down as he slides to base is he balanced or unbalanced?

Answers

Answer : this pretty much gives you the answer Lol

Explanation:

Fundamentals. When the forces acting upon an object are balanced, the object will maintain its state of motion; that is, its velocity remains constant. If the forces are unbalanced, the object will either speed up or SLOW DOWN. ... And if an object is speeding up or slowing down, the forces are unbalanced.

What are the elements of an electric circuit?

An electric circuit is the continuous closed path along which the electric current flows from the positive terminal of the circuit to the negative terminal of the battery. An electric circuit can be constructed easily by joining all the elements of the circuit together in order.

The components of an electric circuit are:

A cell or a battery, which is the source of electricity.

The connecting wires which act as conductor to flow electric current.

A key or a switch to control the current through the circuit.

A bulb or electric device which act as a load to the circuit.

The length of the electric wire increases the resistance through the circuit and decreases the current flowing through the circuit which in turn dims the bulb.

Therefore, the correct option is B.

On Earth, a scale shows that you weigh 585 N. What would the scale read on the Moon (g = 1.60 m/s2)? N

Answers

Answer:

95.51 N

Explanation:

First, find the mass in kg:

Fg = 585 N

Fg = m*g

585 N = m*9.8 m/s^2

m = 59.69 kg

Then, to find your weight (Fg) on the moon, you use the same equation of

Fg(moon) = m*g, except this time g = 1.60 m/s^2

Fg(moon) = 59.69 kg * 1.60 m/s^2

Fg(moon) = 95.51 N

10 A ship is made of 4000 m' steel of density
7900 kgm^3
a. What volume of fresh water
1000 kg m) would the ship need to
displace in order for it to float?

b. Explain how the design of the ship enables
it to displace this much water.​

Answers

Answer:

Explanation:

mass of ship = volume x density

= 4000 x 7900 = 316 x 10⁵ kg

The ship must displace water equal to weight of ship that is 316 x 10⁵ kg .

If volume of displaced water be V .

V x 10³ is mass of displaced water

V x 10³ = 316 x 10⁵

V = 31600 m³.

b ) Now the volume of steel making ship is only 4000 m³ so if it is in the form of a lump , it will displace only water equal to its volume ie 4000 m³ . So in order that it may displace water equal to volume 31600 m³ , it must be given shape so that it is hollow .

Kimora is very concerned about the lack of care for homeless cats and dogs. She proposes legislation whereby citizens of all states are to be taxed sufficiently to provide for no-kill animal shelters, and that citizens in states with higher-than-average incomes are to be taxed at a higher rate than citizens of other states. She also proposes that federal funds for state highways be denied to any state that fails to provide assistance to low-income citizens in covering pet vaccinations. Jose, another new senator, tells Kimora that, apart from the mandated federal income tax, Congress lacks the authority to tax states because the U.S. Constitution expressly reserves that right to the states. Sven, another senator, tells Kimora that Congress has no authority to link highway funds or any other funds with social welfare objectives.
