A heavy piano is pushed up an inclined plane into a moving van. Which of the following choices best explains how the inclined plane made the task easier?
1. The force needed to move the piano up the plane was less than the force needed to lift it straight up into the van, but the distance over which the piano moved was greater.
2.The force exerted on the piano was the same as if it had been lifted, but the distance it needed to be move decreased, so the total work decreased.
3.The distance that the piano was moved was less that the distance it would have had to be lifted, so the total work decreased.
4. The amount of force need to push the piano up the ramp is the same as the force needed to lift it, so the amount of work remained the same.

The term mechanical advantage has to do with the ratio of the load to the effort.
What is mechanical advantage?
The term mechanical advantage has to do with the ratio of the load to the effort. There is a mechanical advantage when the effort applied is less than the load.
Hence, the task is made easier because the force needed to move the piano up the plane was less than the force needed to lift it straight up into the van, but the distance over which the piano moved was greater.

At high elevations or high latitudes, some of the water that falls on land does not immediately soak in , run off, evaporate or transpire. where is the water being temporarily stored?
Answers
Answer:
The water is stored in ice sheets and as snow
Explanation:
Temperature reduces with an increase in altitudes. The standard laps rate is 6.5°C per 1,000 m gained in elevation
At very high elevations, therefore, the air is usually very cold such that when an elevation of 4,500 meters is reached at the equator, it is possible to observe snowfall and the water remain temporarily stored on the surface of the mountain as ice and snow

If water is flowing in a 1-inch diameter pipe with an average velocity of 3 m/s and the wall roughness is 400 microns, calculate the wall shear stress.
Answers
Answer:
Shear stress is 50.63 Pascal
Explanation:
As we know shear stress = [tex]\frac{\rho V^2 f}{8} \\[/tex]
Rho is the density
V is the velocity
f is the value from Moody's chart
We will know determine Reynolds number to determine the flow type and then the f value
[tex]R_e = \frac{ \rho*V*D}{u}[/tex]
[tex]R_e = \frac{1000*3*0.0254}{0.001} = 76200[/tex]
This is a turbulent flow and hence the roughness index is [tex]\frac{E}{D} = 0.0157[/tex], From this we get f = 0.045
Now shear stress = [tex]\frac{1000 * 3^2 * 0.045}{8} = 50.63[/tex] Pa

Name the type of component that has a greater resistance as the current through it increases
Answers
Answer:
filament bulb, filament lamp
Explanation:
More length of a wire is a component that has a greater resistance as the current through it increases.
The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions present in the wire as they pass through. The moving electrons can collide with the ions present in the metal.
This makes more difficult for the current to flow and causes resistance in the wire so we can conclude that more length of a wire is a component that has greater resistance as more current passes through it.

A tuning fork vibrating in water with a frequency of 840 Hz produces waves that are 2.5 m long. If a tuning fork vibrating at 500 Hz produces the same type of wave in water, what will the wavelength of the waves be?
A) 1.5 m
B) 4.2 m
C) 3.2 m
D) 2.5 m
Answers
Answer:
Option B
Explanation:
As we know
Frequency (F) * wavelength (W) = C (speed of light - can also be taken as constant)
Hence,
[tex]F1 W1 = C\\F2W2 = C[/tex]
Or [tex]F1W1 = F2W2[/tex]
Substituting the given values, we get -
[tex]840 *2.5 = 500 *XX = 4.2[/tex] m
Hence, option B is correct

Explanation:
Humidity is the total concentration of water in the atmosphere or air. Dew point can be defined as the temperature at which the air get saturated into vapors. Clouds are the mass of water vapors enters into higher atmosphere due to evaporation these water vapors when condense they result in precipitation in the form of rain, hail, and others.

Two charges, one with a charge of +10.0 x 10-6 C, the other with a charge of -3 x 10-6 C exert a force on each other with a magnitude of 1.7 Newtons on each other. Is this a repulsive or attractive force. What is the separation distance of these charges?
Answers
Answer:
b.
Explanation:
Answer:
Attractive force and r = 0.399 m
Explanation:
One charge is positive and the other charge is negative. Opposite charges attract, so there has to be a force that attracts between them.
q1 = 10.0 x 10^-6 C
q2 = -3 x 10^-6 C
F = 1.7 N
Plug those values into Coulomb's Law:
[tex]F = k\frac{q1q2}{r^{2} } \\1.7 = \frac{(9x10^{9})(10.0 x 10^{-6})(-3 x 10^{-6})}{r^{2} }[/tex]
Solve for r
r = 0.399 m
The left end of a spring is attached to a wall. When Bob pulls on the right end with a 200 N force, he stretches the spring by 20 cm. The same spring is then used for a tug-of-war between Bob and Carlos. Each pulls on his end of the spring with a 200 N force. How far does the spring stretch
Answers
Answer:
40 cm
Explanation:
Since Bob pulls with a force of F = 200 N when the spring is attached to the wall and it extends a length x = 20 cm, from Hooke's law,
F = kx where k = spring constant
So, k = F/x = 200 N/20 cm = 10 N/cm
Now, sine both Bob and Carlos pull with a force of F = 200 N in opposite directions, the spring stretches about its center and has an extension, x' in each direction.
So, from F = kx
x = F/k = 200 N/10 N/cm = 20 cm
So, the spring stretches 20 cm in both directions.
So, the total extension is thus x' + x' = 2x' = 2(20 cm) = 40 cm
The spring will stretch 40 cm.When a force is act om the spring the spring will stretch or compress depeds on the application of force.
What is hooke's law?Hooke's law states that the force used to extend the spring is directly equal to the amount of stretch.
The force needed to extend the spring is proportional to its displacement. It is stated as
F=Kx
The given data in the problem is;
F is the force of pull to bob= 200 N
x is the length of extension= 20 cm.
F' is the force act on the another end= 200 N
According to Hooke's law,
[tex]\rm F = Kx \\\\ \rm K= \frac{F}{x} \\\\ \rm K= \frac{200}{20} \\\\ \rm K=10 \ N/cm[/tex]
The extension due to another end force is found by;
[tex]\rm x' = \frac{F}{K} \\\\ \rm x' = \frac{200}{10} \\\\ \rm x' = 20[/tex]
The total extension of the spring will be;
[tex]\rm x_t = x+x' \\\\ \rm x_t = 2(20) \\\\ \rm x_t =40\ cm[/tex]
Hence the spring will stretch 40 cm.

In which of these can convection not occur
A. Gases
B.solids
C.liquids
D.fluids
Answers
I believe the answer would be B.solids.
Explanation:
Hope this helped!
In solids these can convection not occur and convection can occur in both liquids and gases, as they are both considered fluids. Thus, option B is correct.
However, convection cannot occur in solids, as the particles in solids are generally fixed in position and do not have the freedom to move and transfer heat through bulk motion as in convection.
A solid is one of the three fundamental states of matter, along with liquids and gases. It is characterized by having a definite shape and volume. Solids are composed of tightly packed particles, such as atoms, molecules, or ions, that are held together by strong intermolecular forces.
These particles vibrate in fixed positions but do not have the ability to move freely throughout the substance. As a result, solids maintain their shape and volume under normal conditions and exhibit relatively low compressibility compared to gases and liquids. Examples of solids include metals, rocks, wood, plastics, and ice.
