Two organ pipes, open at one end but closed at the other, are each 1.03 m long. one is now lengthened by 2.00 cm. find the frequency of the beat they produce when playing together in their fundamental

Answer:

48 km/hr

Explanation:

These are often calculated incorrectly because TIME is ignored

time = distance / rate

               uphill =  d / 40       downhill = d/60

average rate =   distance / time

                      =   2d / ( d/40 + d/60)              2d is uphill + downhill

                        = 2 / ( 1/40 + 1/60 ) =   48 km/hr

According to the given statement  the pulse pressure = 70mm Hg.

The correct option is 2.

Systolic, as well as diastolic blood pressure, as well as diastolic blood pressure, is divided to create pulse pressure. Mercury millimeters are used to measure it (mmHg).It represents the contractional force of the beating heart. Normal rested blood pressure is about 120/80 mmHg, which results in a pulse pressure of about 40 mmHg.

Diastolic blood pressure is subtracted from systolic blood pressure to determine pulse pressure. Age-related changes in the aorta and minor arteries' compliance result in elevated systolic pressure and decreased diastolic pressure, which raises pulse pressure.

Diastolic and systolic blood pressure differences are used to compute pulse pressure.

So, 150 - 80

= 70.

The intersection of the sphere with the yz- plane will be (y -z)² + (z- 5)² =7

A sphere is can be define as , a geometrical object that has a three-dimensional analogue to a two-dimensional circle. In a very simple word, i.e. a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.

We are given that ,

The center of sphere = (h, k, l) = (-3,2,5)

The radius of sphere = (r) = 4

Then the formula of the equation of sphere with radius r and center (h, k, l) is given as,

(x- h)² +(y - k)² + ( z -l)² = r²

So that putting the value of center of sphere (h, k, l) and radius (r) in above equation then we get,

(x- (-3))² +(y - 2)² + ( z -5)² = 4²

(x +3 )² +( y - 2)² + ( z -5)² = 16

Therefore, we can write the equation of intersection of the sphere with the yz- plane and putting (x = 0) in above equation then,

(0 +3 )² +( y - 2)² + ( z -5)² = 16

( y - 2)² + ( z -5)² = 16 - 9

( y - 2)² + ( z -5)² = 7

The intersection of the sphere with the yz- plane is, (y -z)² + (z- 5)² =7

When the total debt ratio is 0.36, the debt-equity ratio is 0.5625.

The debt-to-equity ratio is a financial metric that shows how much debt and shareholder equity were utilized to finance the assets of a company. The ratio, often known as risk, gearing, or leverage, is closely related to leveraging. The debt-equity ratio serves as a gauge for how equally creditors and owners or shareholders contributed to the capital used by the company. The debt-equity ratio is the simple ratio of all long-term debt and equity capital in the company. The debt-to-equity ratio is calculated by dividing a company's total liabilities by the sum of its shareholders' equity. For the majority of businesses and industries, a desirable debt-to-equity ratio is around 2.0. A high debt-to-equity ratio shows that a business is using more market capital to finance its operations, whereas a low debt-to-equity ratio shows that the business is making better use of its assets and using less market capital. The debt-to-equity ratio is often higher in the capital industries.

Total Debt ratio = Debt/Asset

Hence, Debt=0.36*Total Assets

Assets = Debt*Equity

Hence Equity=(1-0.36)*Total Assets=0.64*Total Assets

So, Debt-Equity Ratio=Debt/Equity

=0.36Total assets/0.64Total assets

=0.5625

⇒Debt-Equity Ratio=0.5625

The minimum speed the ball must be served so as to clear the net is 25.69 m / s

We know that,

Speed = Distance / Time

In order to calculate the time, we can use one of the equations of motion,

y = [tex]y_{0}[/tex] + [tex]v_{0}[/tex]t + 1/2 a[tex]t^{2}[/tex]

where,

y = Initial height

[tex]y_{0}[/tex] = Final height

[tex]v_{0}[/tex] = Initial velocity

a = Acceleration due to gravity

t = Time

Given that,

y = 2.7 m

[tex]y_{0}[/tex] = 1.08 m

[tex]v_{0}[/tex] = 0

a = -9.81 m / [tex]s^{2}[/tex] (Due to gravity)

Distance = 14.9 m

y = [tex]y_{0}[/tex] + [tex]v_{0}[/tex]t + 1/2 a[tex]t^{2}[/tex]

2.7 = 1.08 + 0 + 1/2  * ( -9.81 ) * [tex]t^{2}[/tex]

[tex]t^{2}[/tex] = 1.62 / ( - 4.9 ) = 0.33

t = 0.58 s

Speed = 14.9 / 0.58

Speed = 25.69 m / s

Velocity (speed) is the rate of change of distance with respect to time. It is denoted as V.

Therefore, the minimum speed the ball must be served so as to clear the net is 25.69 m / s

The stopping distance is 62.5m for a car traveling at vxvxv_x = 25 m/sm/s and the driver applies the brakes and the car decelerates at axaxa_x = -5.0 m/s2m/s2.

Explanation:

Acceleration occurring in the opposite direction of an object’s the motion, is negative or referred to as deceleration. The formula below (stopping distance) solely compares the magnitudes of distance travelled, beginning velocity, and deceleration.

We use the fourth equation of motion, v2 = u2 +2ax. When the car stops, we have v = 0, and so

0 = u2 +2ax.

Solving for x, we have

x =−u2/2a

Given the following information from the question

Answer:

Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches.

MECHANICS :

Mechanics is the branch of physics that deals with the motion of an object without or with the reference of force. Mechanics can be further divided into two branches, namely quantum mechanics and classical mechanics. Quantum mechanics deals with the behaviour of the smallest particles like neutrons, protons, and electrons, while classical mechanics is the branch that deals with laws of motion of forces and physical objects.

OPTICS :

This branch of physics deals with the behaviour, propagation, and properties of light. Optics can be simply described as the study of the behaviour of infrared light, visible light, and ultraviolet.

THERMODYNAMICS:

Thermodynamics deals with the study of heat and its relation with work and energy. Thermodynamics also deals with the transmission of heat energy by means of convection, conduction, and radiation.

ELECTROMAGNETISM:

Electromagnetism deals with the study of electromagnetic force like electric fields, light, magnetic fields, etc. There are two aspects of electromagnetism which are “electricity” and “magnetism”.

RELATIVITY:

This branch of physics deals with the theorem that was formulated by Albert Einstein. The theory of relativity states that space and time are relative and all the motion must be relative to a frame of reference.

ACOUSTICS :

Acoustics deals with the study of sound and its transmission, production, and effects. Acoustics mainly involves the mechanical waves in gases, liquids, and solids, which include vibration, sound, ultrasound, and infrasound.
