Answer:

Main Sequence star

Explanation:

Hertzsprung-Russell (H-R) diagram is a scatter plot showing the relation b/w a star's absolute magnitude and its temperature.  Through this diagram one can predict the life cycle of a star and its classification. Our Star, the Sun, is a main sequence star on H-R diagram.

What water pressure must a pump that is located on the first floor supply to have water on the thirteenth of a building with a p
irga5000 [103]

The water pressure on the first floor must be 455 PSI in order to push the water to the 13th floor at the given pressure.

The given parameters;

  • <em>Pressure on the 13 th floor, P₁ = 35 PSI</em>
  • <em>Distance between each floor, d = 10 ft</em>

The vertical pressure of the water is calculated as follows;

P = \rho gh\\\\\frac{P}{h} = \rho g\\\\\frac{P}{h} = k\\\\\frac{P_1}{h_1} = \frac{P_2}{h_2} \\\\

The vertical height of the first floor from the 13th floor = 130 ft

The vertical height of the 13 ft floor = 10  ft

P_1 = \frac{P_2 h_1}{h_2} \\\\P_1 = \frac{35 \times 130}{10} \\\\P_1 = 455 \ PSI

Thus, the water pressure on the first floor must be 455 PSI in order to push the water to the 13th floor at the given pressure.

You want to manufacture a guitar such that the instrument will be in tune when each of the strings are tightened to the same ten
charle [14.2K]

Answer:

0.000507 kg/m

Explanation:

L = Length of string

T = Tension

\mu = Mass density of string

E denotes the E string

D denotes the D String

Frequency is given by

f=\dfrac{1}{2L}\sqrt{\dfrac{T}{\mu}}

So

f\propto \sqrt{\dfrac{1}{\mu}}

\dfrac{f_D}{f_E}=\sqrt{\dfrac{\mu_E}{\mu_D}}\\\Rightarrow \mu_E=\dfrac{f_D^2}{f_E^2}\mu_D\\\Rightarrow \mu_E=\dfrac{146.83^2}{329.63^2}\times 0.00256\\\Rightarrow \mu_E=0.000507\ kg/m

The mass density of the E string is 0.000507 kg/m

sleet_krkn [62]

Answer:

The answer is below

Explanation:

Dear Friend,

I received your letter a few days back. And because I was busy with work, I couldn't write a reply to you immediately. However, here is my well-detailed reply to your request. I hope you find it satisfactory. I am excited to learn that you wish to go on a tour to Nepal. For the advice, here is my suggestion for some places for you to visit.

1. Kathmandu: this is the capital of Nepal. It also doubles as the capital city. The atmosphere there is electric. The streets are wide and there are old monumental buildings there.

2. Bhaktapur: here you find interesting things around. It is the third-largest royal city. Durbar square is a nice place to visit.

3. Pokhara: this place has the largest population and the city is cleaner compared to most other big cities around. It has wonderful places to relax. And if you enjoy hiking this is the place for you.

4. Chitwan National Park: I know you love watching wildlife. So this is a must for you to visit. You get to see amazing animals such as rhinos, Bengal tigers, leopards, etc.

However, due to space and for me not to bore you, here are other honorable mentions

Trekking in the Langtang region, Swayambhunath, known as Monkey Temple. You should also consider the Everest & the Trek to Base Camp.

I hope you will enjoy your stay to the fullest. Don't forget to send me details of your tour after your visit.

I love you, friend.

Yours sincerely,

MyName
