You drop a stone down a well that is 9.5 m deep. how long is it before you hear the splash? the 9) speed of sound in air is 343 m/s and air resistance is negligible.

[ad_1]

Answer:

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²    

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

D. To move the reader toward the climax of the story This is the correct naswer.

Authors create tension to engage the readers. Tension is what makes a story  worth reading since it will touch or move the reader’s feelings. The reader’s rational side will be set aside by his/ her emotions.

These answers are not right:

A. To introduce the characters in the story and describe where the story takes place  ( This is part of the setting).

B. To reveal the author’s personal bias and opinion ( The opinion should be infered through the whole story , not jut through the tension in it).

C. To neatly tie up loose ends at the story’s close ( The tension leads to the climax not to the end of the story),

Which excerpt from “The Man to Send Rain Clouds” best illustrates how Leon’s beliefs differ from those of Father Paul? “Well, I’m glad you understand. I hope I’ll be seeing you at Mass this week—we missed you last Sunday. See if you can get old Teofilo to come with you.” The priest smiled and waved at them as they drove away. Leon walked toward the old man’s bed. The red plaid shawl had been shaken and spread carefully over the bed, and a new brown flannel shirt and pair of stiff new Levi’s were arranged neatly beside the pillow. It was noontime now because the church bells rang the Angelus. They ate the beans with hot bread, and nobody said anything until after Teresa poured the coffee. Leon turned to look up at the high blue mountains in the deep snow that reflected a faint red light from the west. He felt good because it was finished, and he was happy about the sprinkling of the holy water; now the old man could send them big thunderclouds for sure.

If the telescope is 1 m deep and 8 m wide, how far is the focus from the vertex? 1 2 4 16 Find the vertex, focus, directrix, and focal width of the parabola. negative 1 divided by 12 times x squared = y

[ad_1]

First, let me introduce the general equation of the parabola:

(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where

(h,k) are the coordinates of the vertex
a is the distance of the vertex to the focus
4a = length of lactus rectum or the focal width

If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis). 

The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:

x^2 = -12y
Therefore, 

-4a = -12
4a = 12
a = 3, and the parabola is facing downwards.

The vertex is (0,0) at the origin.
The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.
The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3
Focal width is 4a which is equal to 12 units.

A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting? A.Compression B.Strong nuclear force C.Tension D.Air resistance

[ad_1]

The equation for how temperature changes the resistance R is: 

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. 

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.  

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

Answer:    Joshua is correct

Explanation:  Animals, however well preserved and bred in conditions that are not in nature, that is, not in their natural habitat, animals still retain the animal instinct. Thus, young animals in the wild can be met daily, except for members of their species, and members of all other species, including predators, as well as humans. This means that in the natural environment, young animals can find themselves in a variety of dangers on a daily basis, but not only that. In this way young animals develop their ability to survive, escape from predators, manage, and develop their hunting skills, etc. All this is essential for socialization because according to all these developed skills and abilities their socialization depends. To deny any of the conditions prevailing in the wild means to deny the development of any skill or instinct, to deny proper socialization.

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

The frequency of light that has a wavelength of 249 nm is about 1.20 × 10¹⁵ sec⁻¹

Further explanation

The term of package of electromagnetic wave radiation energy was first introduced by Max Planck. He termed it with photons with the magnitude is :

large {boxed {E = h times f}}

E = Energi of A Photon ( Joule )

h = Planck’s Constant ( 6.63 × 10⁻³⁴ Js )

f = Frequency of Eletromagnetic Wave ( Hz )

The photoelectric effect is an effect in which electrons are released from the metal surface when illuminated by electromagnetic waves with large enough of radiation energy.

large {boxed {E = frac{1}{2}mv^2 + Phi}}

large {boxed {E = qV + Phi}}

E = Energi of A Photon ( Joule )

m = Mass of an Electron ( kg )

v = Electron Release Speed ( m/s )

Ф = Work Function of Metal ( Joule )

q = Charge of an Electron ( Coulomb )

V = Stopping Potential ( Volt )

Let us now tackle the problem !

Given:

λ = 249 nm = 2,49 × 10⁻⁷ m

A fuel oil tank is an upright cylinder, buried so that its circular top is 14 feet beneath ground level. the tank has a radius of 5 feet and is 15 feet high, although the current oil level is only 14 feet deep. calculate the work required to pump all of the oil to the surface. oil weighs 50lb/ft350lb/ft3.

[ad_1]

Say we have a cylinder
that has a height of dx, we see that the cylinder has a volume of: 

Vcylinder = πr^2*h = π(5)^2(dx) = 25π dx

Then, the weight of oil in this cylinder is: 

Fcylinder = 50 * Vcylinder = (50)(25π dx) = 1250π dx. 

Then, since the oil x feet from the top of the tank needs to
travel x feet to get the top, we have: 

Wcylinder = Force x Distance = (1250π dx)(x) = 1250π x dx. 

Integrating from x1 to x2 ft gives the total work to be: (x1
= distance from top liquid level to ground level; x2 = distance from bottom
liquid level to ground level)

W = ∫ 1250π x dx  
W = 1250π ∫ x dx
W = 625π * (x2 – x1)

x2 = 14 ft  + 15 ft = 29 ft

x1 = 14 ft + 1 ft = 15
ft


W = 625π * (29^2 – 15^2) 
W = 385,000π ft-lbs
= 1,209,513.17 ft-lbs

In a residential solar thermal system, called the Solar Heating System, the solar panels are of the Solar Thermal Collector type, which have the function of capturing the thermal energy of the solar radiation and transferring it to the water, heating it.
This water will be stored in a thermal reservoir, which will maintain its temperature until the moment of use.
The size of the reservoir and the area of solar thermal collectors (solar heating plates) required for the solar heating system vary according to the amount of hot water used in the residence.
This is simple to calculate after an interview with the residents, where the consumption profile will be studied according to the habits of bathing, washing utensils, clothes, etc.

In a residential solar photovoltaic generator system the solar panels are of the photovoltaic module type, consisting of photovoltaic solar cells that transform solar radiation into direct current electric energy.
For the operation of an on-grid photovoltaic solar system (connected to the grid) it is necessary to use a grid-tie inverter, which converts the energy generated into continuous currents by the photovoltaic solar panels into current electric energy Alternating.
The grid-tie inverter is then connected to the general picture of the residence, where it is in charge of mixing the solar energy (already in alternating current) with the power of the public network, allowing to use it in any apparatus or electrical equipment.
