For precipitation to form, cloud droplets must grow in volume by roughly __________ times.

Answers

For precipitation to form, cloud droplets must grow in volume by roughly one million times.

Hope I helped :)

The correct answer is by roughly one million times.  

Any product of the condensation of atmospheric water vapor, which falls under gravity is known as precipitation. The main forms of precipitation are rain, drizzle, snow, sleet, and others.  

All the precipitation give rise to clouds and the clouds are produced when water vapor in the atmosphere condenses and cools. With the condensation of water vapor, the formation of water droplets takes place, and if the formation of clouds takes place within or is moved into the part of the atmosphere, which is below freezing then the droplets turn into ice crystals.  

In order to form precipitation, the cloud droplets must grow in volume by roughly one million times.

9. How does the length of the hypotenuse in a right triangle relate to the lengths of the legs? (2 points)
Open ended/Short answer question

Answers

Answer:

hypotenuse² = base² +height²

Explanation:

Let us suppose a right angled triangle having b as base, h as hypotenuse and p as perpendicular distance.

The relation between the length of legs, the base and the hypotenuse is called Pythagoras theorem. It is given by :

[tex]h^2=b^2+p^2[/tex]

or

hypotenuse² = base² +height²

Answer:

The relation between the length of the hypotenuse in a right triangle and  lengths of the legs is [tex]H^{2} = p^{2}+b^{2}[/tex].

Explanation:

The legs of right angled triangle is also known as perpendicular and base respectively.

Let p be length of perpendicular and b be the length of base. Then by Pythagoras theorem,

[tex]H^{2} = p^{2}+b^{2}[/tex]

here, H is the length of Hypotaneous.

Thus, relation between the length of the hypotenuse in a right triangle and  lengths of the legs is [tex]H^{2} = p^{2}+b^{2}[/tex].

A certain radio wave has a frequency of 2.0 x 10^6 Hz. What is its wavelength?

Can someone help me solve this??

Answers

Solution:  
Formula for finding wavelength from frequency is wavelength=wave velocity(c)/frequency(f). 
 General value of Wave velocity (c) = 3 x 10^8 m/s
 Given frequency = 2.0 x 10^6 Hz 
 Now,
 Wavelength = 3 x 10^8 m/s / 2.0 x 10^6 Hz
  = 150 m
 Therefore the value of wavelength is 150m.

Two vectors A and B have precisely equal magnitudes. In order for the magnitude of A+ B to be 110 times larger than the magnitude of A-B , what must be the angle between them?,

Answers

Due to the magnitudes, as mentioned in the problem, being equal, B has components Acos(θ)x along the x-axis and Asin(θ) along the y-axis. 

The solution is as follows:

A+B has: 
total x-component = A + Acos(θ) = A(1+cos(θ)) 
total y-component = 0 + Asin(θ) = Asin(θ) 
Resultant = √[( A(1+cos(θ)))² + (Asin(θ))²] 
= A√[1 + 2cos(θ) + cos²(θ) + sin²(θ)] 
=A√[2 + 2cos(θ)] 

A-B has: 
total x-component = A - Acos(θ) = A(1-cos(θ)) 
total y-component = 0 - Asin(θ) = -Asin(θ) 
Resultant = √[( A(1-cos(θ)))² + (-Asin(θ))²] 
= A√[1 - 2cos(θ) + cos²(θ) + sin²(θ)] 
=A√[2 - 2cos(θ)] 

A+B/A-B = [A√[2 + 2cos(θ)]] / A√[2 - 2cos(θ)] 
= [√[2 + 2cos(θ)]] / [√[2 - 2cos(θ)]] 

110 = [√[1 + cos(θ)]] / [√[1 - cos(θ)]] 
12100 = [1 + cos(θ)] / [1 - cos(θ)] 

12100 - 12100cos(θ) = 1 + cos(θ)
12101cos(θ)] = 12099 
cos(θ)= 0.999834724

a bicyclist in the Tour De France crests a mountain pass as he moves at 15km/h. At the bottom 4km/h farther, his speed is 75km/h. What is his average acceleration(m/s^2) while riding down the mountain?,

Answers

For an uniformly accelerated motion, the following relationship can be used:
[tex]2aS = v_f^2 -v_i^2[/tex]
where a is the acceleration, S the distance covered, vf the final speed and vi the initial speed.

Before using the formula, we need to convert everything into SI units.
The distance covered is:
[tex]S=4 km=4000 m[/tex]
To convert the speed from km/h to m/s, let's keep in mind that
[tex]1 km=1000 m[/tex]
[tex]1h=3600 s[/tex]
so
[tex]1 \frac{km}{h}= \frac{1000 m}{3600 s}= \frac{1}{3.6} [/tex]
is the conversion factor.
So the speeds are:
[tex]v_i = 15 km/h \cdot \frac{1}{3.6}=4.17 m/s [/tex]
[tex]v_f = 75 km/h \cdot \frac{1}{3.6}=20.83 m/s [/tex]

and so, now we can re-arrange the formula to find a, the average acceleration:
[tex]a= \frac{v_f^2-v_i^2}{2S} = \frac{(20.83m/s)^2-(4.17m/s)^2}{2\cdot 4000 m}=0.05 m/s^2 [/tex]

Work can _____ energy between objects and can cause a change in the form of energy.

A. Transfer
B. Change
C. Increase
D. Decrease

Answers

Answer:

Work can transfer energy between objects and can cause a change in the form of energy.

Explanation:

The best explanation can be done with an example.Consider an apple of mass m falling from a tree. Initially, the apple is at rest on the tree, at a certain height h above the ground, so it has a form of energy called gravitational potential energy, equal to: where g is the acceleration due to gravity.As the apple falls, the force of gravity acts on it, and so this force does work on the apple. As a result, the potential energy of the apple is converted into another form of energy, kinetic energy, which is the energy due to the motion of the apple: where v is the speed of the apple.Consider another example: a man pushing a box along the floor with a force F. The man is doing work on the box, and this work is equal towhere d is the displacement of the box. As a result of this work, some of the chemical energy contained in the muscles of the man is transferred into the box and converted to kinetic energy of the box, which is put in motion and it gains a certain speed v. In particular, if there are no frictional forces involved, the work done by the man is equal to the kinetic energy gained by the box.

2. What happens when multiple forces act on an object? (Points : 1)
A. The object will always move.

B. The object will move if the forces are balanced.

C. The object will move if the forces are unbalanced.

D. The object will always stay in place.



3. An object moves in the direction of the __________ force. (Points : 1)
A. net

B. balanced

C. strongest

D. weakest

Answers

2. C. The object will move if the forces are unbalanced. 

3. A. Net force.
The answer to 2) is C - the object will move if the forces are unbalanced. This is a rephrasing of Newton's Second Law, which states that a net force will cause acceleration in the direction of that force. Similarly, the answer to 3), keeping in line with Newton's Second Law, is that an object will move in the direction of the A. net force.

What are some possible sources of error when using the modified mercalli scale to locate the epicenter of an earthquake?

Answers

Effect differs from one location to another and hence different magnitude may be arrived at, yet the same Earth quake regardless of the epicenter. This effect could be  affected by people related factors as well as buildings resilience.

The Modified Mercalli scale is used measures the amount of damage done during an earthquake. This helps to locate the epicenter of the earthquake.  It depicts the intensity of the earthquake based on the damage occurred due to the earthquake. The responses from many people who experienced the earthquake are collected by the scientists, assigned a value and plotted on a map

The plotted number can change with the reference place within the region of disturbance. It depends on the location of the observer with reference to the epicenter of the earthquake. The reporting depends on the witness. Some can exaggerate the extent of damage caused. All  the above mentioned are possible sources of error  when using the Modified Mercalli scale to locate the earthquake's epicenter.

Answers

When the key is off there should be no current in the circuit. 
Our ammeter still measures some current, and this is called hysteresis error. This means that this particular ammeter is going to add some amount of current to any current measured. In order to compensate for this error, we simply we deduct it from all measurements.
Each mark on the ammeter is worth:
[tex]m=\frac{100mA}{20}=5mA[/tex]
This means that our error is:
[tex]e_r=3\cdot m=15mA[/tex]
When the circuit is closed we measure:
[tex]I_{er}=200mA+17\cdot m=285mA[/tex]
This is current with the error, real current in the circuit is:

Explanation:

Final answer:

The group incorrectly assumes that ozone layer depletion is connected to global warming when they are separate issues. Ozone depletion is about the loss of stratospheric ozone that protects from ultraviolet radiation, while global warming concerns the greenhouse gas effect and climate change.

Explanation:

The major flaw in the reasoning of the political action group that wants to overturn the Montreal Protocol is c. The loss of stratospheric ozone is not connected to global warming. There is a common misconception that ozone layer depletion and global warming are directly related, but they are in fact separate phenomena resulting from different processes in the atmosphere. The ozone layer, consisting of ozone (O3) molecules, is crucial for absorbing harmful ultraviolet radiation from the sun and thereby protecting living organisms. The Montreal Protocol aimed to reduce the production and release of industrial chemicals like chlorofluorocarbons (CFCs), which were proven to contribute to ozone depletion. While the protocol led to a significant reduction in CFCs and a gradual recovery of the ozone layer, this effort is different from initiatives like the Kyoto Protocol, which address greenhouse gas emissions and aim to mitigate global warming.

A piano tuner stretches a steel piano wire with a tension of 1000 n. the wire is 0.5 m long and has a mass of 5 g. what is the number of the highest harmonic that could be recorded by a computer that is capable of sensing frequencies up to 10,000 hz

Answers

The frequencies of the n-harmonics of a string is given by
[tex]f_n = \frac{n}{2L} \sqrt{ \frac{T}{\mu} } [/tex]
where n is the number of the harmonic, L the length of the wire, T the tension and [tex]\mu = \frac{m}{L} [/tex] is the linear density, with m being the mass of the string.
Let's calculate the linear density first, using the mass [tex]m=5 g=5 \cdot 10^{-3}kg[/tex]:
[tex]\mu = \frac{m}{L} = \frac{5\cdot 10^-3 kg}{0.5 m}=0.01 kg/m [/tex]
The problem says that the computer is able to analyze frequencies up to 10000 Hz. This means that we have to find the highest number of harmonic that generates a frequency smaller than this value. So, using [tex]f=10000 Hz[/tex], the tension of the string [tex]T=1000 N[/tex] and the mass m and the length of the string L, we can re-arrange the previous formula to find which n corresponds to this frequency:
[tex]n = 2f_n L \sqrt{ \frac{\mu}{T} }=2 (10000 Hz)(0.5 m) \sqrt{ \frac{0.01 kg/m}{1000 N} }=31.6 [/tex]
And since n can only be integer, the highest harmonic that can be analyzed by the computer is n=31.

A certain instant camera determines the distance to the subject by sending out a sound wave and measuring the time needed for the wave echo to return to the camera. how long would it take the sound wave to return to the camera if the subject were 3.42 m away? the speed of sound is 343 m/s. answer in units of s.

Answers

Final answer:

The time it would take for the sound wave to travel to a subject 3.42m away and back, with a sound speed of 343 m/s, is approximately 0.01995 seconds.

Explanation:

The time it takes for the sound wave to return to the camera can be found by applying the equation distance = speed * time. This principle is often utilized in technologies such as sonar and ultrasound imaging. Here the distance is doubled since the sound has to travel to the subject and back to the camera. If the subject is 3.42 m away, the total distance covered by the sound wave is 3.42m * 2 = 6.84m. Given that the speed of sound is 343 m/s, we can rearrange the equation to solve for time: time = distance/speed. Hence, time = 6.84m / 343 m/s = 0.01995 s, rounded to 5 decimal places.

It takes 0.02 seconds for the sound wave to return to the camera if the subject were 3.42 metres away.

The given question can be solved by simple use of kinematic equations. It is given that the camera determines the distance to the subject by sending out a sound wave. The speed of the sound wave is v = 343 m/s

Now, for a subject at a distance of 3.42 metres away the sound wave has to travel to the subject and travel back to the camera as well. Therefore the total distance covered by the sound wave will be twice the distance of the subject from the camera.

d = 2 × 3.42 m = 6.84 m

From the kinematic equation;

[tex]v = \frac{d}{t}[/tex], where t = time taken

rearranging for t, we get:

[tex]t = \frac{d}{v}[/tex]

substituting the values,

[tex]t = \frac{6.84 m}{343 m/s}[/tex]

or, t = 0.019 s ≈ 0.02 s

A mixing blade on a food processor extends out 3 inches from its center. if the blade is turning at 600 revolutions per minute, what is the linear velocity of the tip of the blade in feet per minute? (round your answer to the nearest whole number.)

Answers

First let's convert everything into SI units.
The length of the blade is 3 inches. Keeping in mind that 1 inc=0.025 m, we have
[tex]L=3 in \cdot 0.025 \frac{m}{inc} =0.075 m[/tex]
The angular speed is 600 revolutions per minute. Keeping in mind that [tex]1 rev=2 \pi rad[/tex] and [tex]1 min=60 s[/tex], the angular speed becomes
[tex]\omega = 600 \frac{rev}{min} \frac{2 \pi rad/rev}{60 s/min}=62.8 rad/s [/tex]

And so, the linear velocity of the edge of the blade is equal to
[tex]v=\omega L=(62.8rad/s)(0.075 m)=47 m/s[/tex]

Answer:

The linear  velocity of the tip of the blade is 940.94 ft/min.

Explanation:

It is given that,

A mixing blade on a food processor extends out 3 inches from its center, r = 3 inches = 0.0762 meters

Angular speed of the blade, [tex]\omega=600\ rev/minute=62.83\ rad/s[/tex]  

Let v is the linear velocity of the tip of the blade. The relation between the angular velocity and the linear velocity is given by :

[tex]v=r\times \omega[/tex]

[tex]v=0.0762\times 62.83[/tex]    

v = 4.78 m/s

or

Since, 1 m/s = 196.85 ft/min

4.78 m/s = 940.94 ft/min

So, the linear  velocity of the tip of the blade is 940.94 ft/min. Hence, this is the required solution.
