A violin sounds a note of F sharp, with a pitch of 370 Hz. What are the frequencies of the next three harmonics produced with this note?

Answers

Answer:

Answer 740 H z, 1110 H z, 1480 H z

Explanation:

The F sharp note (370 Hz) makes the next three harmonics with frequencies of 740 Hz, 1110 Hz, and 1480 Hz, respectively.

It is necessary to have an understanding of the relationship between harmonics and the fundamental frequency in order to calculate the frequencies of the following three harmonics produced by the note F sharp, which has a pitch of 370 Hz.

The fundamental frequency, denoted by f1, is the first harmonic and corresponds to the frequency of the note (F sharp in this example) when it was initially played. Its pitch is 370 hertz.

The fundamental frequency (f1) is multiplied by two to get the second harmonic frequency (f₂), which is written as f₂ = 2 × f1.

The frequency of the third harmonic (f₃) is equal to three times the frequency of the fundamental tone, or f₃ = 3 × f₁.

The frequency of the fourth harmonic, denoted by f₄, is equal to four times the frequency of the fundamental tone. f₄ = 4 × f₁

If we know that the fundamental frequency, or f₁, is 370 hertz, then we can figure out the frequencies of the following three harmonics, which are as follows:

f₂ = 2 × 370 Hz, which equals 740 Hz

f₃ = 3 times 370 Hz, which equals 1110 Hz; f₄ = 4 times 370 Hz, which equals 1480 Hz

Following the frequency of the F sharp note (370 Hz), the next three harmonics produced have frequencies of 740 Hz, 1110 Hz, and 1480 Hz respectively.

what is the angular displacement of a minute hand of a clock after 3 minutes?​

Answers

Answer:

π/10 rads

Explanation:

It takes an hour (60 minutes) for the minute's hand to turn a full circle or achieve an angular rotation of

2πl rad.

Now, number of periods of 3 minutes in an hour is;

Number of periods = 60/3 = 20 periods

Thus, 3 minutes rotation accounts for 1/20 of 2π the rotation of the minute's hand in an hour.

Thus;

Angular displacement = (1/20) * 2π = π/10 rads

Nepal has high potential for producing hydroelectricity however it is difficult too.
give one reason of each.​

Answers

Answer:

I'm not a scholar of hydroelectric power in Nepal, so consider my answers carefully, below.

Explanation:

High Potential:  Hydroelectric power comes from the potential energy stored in a mass that is above Earth's surface.  As the word "hydro" implies, the mass in this case is water.  Water from snow and glacier melt, and from normal precipitation (rain) in mountainous regions eventually cascades down the mountains in fast-flowing rivers or waterfalls.  Often, there are lakes or man-made reservoirs to collect and store the water before it flows down.  Mt. Everest is 8848 meters tall (about 29,000 feet).    If a lake forms at just 2,000 meters, one can calculate the amount of energy in each kilogram of water stored in the lake that represents the potential energy available at that altitude.  1 kg of water at 2,000 meters has potential energy, PE, according to the equation:  PE = mgh, where m is the mass in kg, g is Earth's acceleration due to gravity (9.8 m/sec^2), and h is height, in meters.  

PE = mGH

PE = (1 kg)*(9.8 m/sec^2)*(2,000 meters) = 19,000 kg*m/sec^2

1 kg*m/sec^2 is the SI unit for 1 Joule, a measure of energy.

This potential energy can be converted into electrical energy by releasing the water so that it can flow down to a water-powered turbine that spins magnets and coils of wire that produce electricity.  The 19,000 Joules of water potential energy can be converted to electrical power, less any inefficiency in the system, such as friction.

Nepal has the natural advantage in that it has many high mountain ranges with water flows that can be used for generating electrical power.  The result is low operating costs (the fuel is the flowing water) and no greenhouse gas emissions

The difficulty in developing hydroelectric power in Nepal is due to the same factor that gives it an advantage:  it is difficult constructing large hydroelectric plants in such rough terrain, and the power lines that are needed to transport the power to its destination are expensive and difficult to maintain and repair.

Take the radially inward direction to be positive) The car’s acceleration is 6.61 m/s2. What is it in g’s? What is the centripetal force acting on the car?

Answers

The car’s acceleration in g’s is equal to 0.67 m/s² and the centripetal force acting on is equal to 4033.47 Newton.

How to calculate the car’s acceleration in g’s?

Since the car’s acceleration is given as 6.61 m/s², we would simply divide it by the acceleration due to gravity (9.8 m/s²) to calculate the car’s acceleration in g’s as follows:

Acceleration, g = 6.61/9.8

Acceleration, g = 0.67 m/s².

What is the centripetal force acting on the car?

Mathematically, the centripetal force acting on this car can be calculated by using this formula:
