1.nstrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building.

other:

A wind vane (also known as a weathervane) is an instrument that tells you the wind direction. Specifically, a wind vane lets you know what direction the wind is coming from.

2. 3. There are three primary types of wind vanes: the classic weathervane, wind sock, and digital wind vane.

Weathervane – In use for centuries, these are the type often seen on top of barns, cathedrals, and a variety of other buildings. Since weathervanes are also used for decorative purposes (in addition to functional applications), they can take on a variety8 of shapes and styles. The classic style features a fin in the shape of a rooster, but a variety of other fin shapes can be featured.

you’ll see situated four horizontal posts that read “N,” “S,” “E,” and “W” (north, south, east, and west) to help the viewer determine the wind direction.

Wind Sock – This type of wind vane is primarily seen in airports, near runways. While a wind sock determines the wind direction, it generally does not indicate a north/south/east/west direction. However, based on how much the sock is inflated, the viewer can estimate the strength of the wind.

This is helpful because, for example, a pilot needs to know the wind direction and strength to help him or her adjust for the wind when landing or taking off. A wind sock can also be beneficial at a golf course, marina, baseball field, or any other location where knowing the wind direction and strength is useful when participating in an activity.

Digital Wind Vane – A digital wind vane shares many basic design elements with a classic weathervane, but is significantly more sophisticated. Quite often, a digital wind vane is seen as a component of a weather station, which will also measure conditions such as wind speed, temperature, humidity, barometric pressure, and sometimes rainfall.

A digital wind vane will either hang from a weather station sensor’s underside, or sit atop a pole or housing of some sort, and rotate on a spindle. At the end of the spindle will usually be an optical sensor that allows a digital processor to know the wind direction, typically up to 16 positions. The reading is sent to a digital display where the wind direction is shown on a circular graphic called a wind rose. Oftentimes, the wind rose will show (in the form of arrows) the current wind direction, as well as the previous two readings.

4.A wind vane can provide a variety of uses. These can include enhanced enjoyment of a recreational activity, safety, protection of property, and the general enjoyment of weather observation.

Safety – Wind conditions play a significant role during severe weather events. If there is a storm in your area, a wind vane can help you determine if it is moving toward you or away from you. Having this information can give you extra time to take action and get your loved ones to a safe location.

Protection of Property – Another advantage of knowing the wind direction during a storm is the ability to determine if your personal property may be in harm’s way. This can offer a chance to make preparations to your home, automobile, yard, and more in an effort to eliminate damage.

Boating, Remote Control Aircraft, Golf, Etc. – Knowing the direction of the wind can help you fine tune a tee shot down a long fairway or adjust the angle of a sail boat. If an activity is affected by the wind, chances are knowing the wind direction can be helpful.

Storm Spotting and Chasing – Storm spotters and chasers work with organizations like the National Weather Service and SKYWARN to provide vital, real-time information during severe weather events. This helps local authorities keep their communities safe. Since the direction a storm is traveling is vitally important to a chaser or spotter’s report, knowing the wind direction is a key piece of information.

Watching the Weather – Weather buffs truly enjoy keeping tabs on weather conditions, just for the fun of it. Having a weather vane provides another key data point, integral to weather observation.

5. The disadvantage is wind vane is not

accurate and unreliable at the time, does

not show the speed of the wind, and

depends on winds breezes and thus is

unable to tell the high pressure and low

pressure in the region.

6. Wind has both speed and direction. Anemometers measure wind speed and wind vanes measure wind direction. (digital)

A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind. (classic)

7. may be the modified wind vane is the digital one which has many features mentioned in previous question.

Answer from: Quest

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule. $\begin{aligned} f(x) & = (0.5)^{2x} \\ f'(x) & = 0.5^{2x} \cdot \ln(0.5) \cdot (2x)' \\ f'(x) & = 0.5^{2x} \cdot \ln(0.5) \cdot 2 \\ f'(x) & = 2\ln(0.5) \cdot 0.5^{2x} \end{aligned}$ set the derivative to equal -1 and solve for x. $\begin{aligned} -1 & = 2\ln(0.5) \cdot 0.5^{2x} \\ -\frac{1}{2} & = \ln(0.5) \cdot 0.5^{2x} \\ -\frac{1}{2\ln(0.5)} & = 0.5^{2x} \end{aligned}$ take log base 10 of both sides. also recall that $\log_c(m^n) = n \log_c m$ . $\begin{aligned} \log\left[ -\frac{1}{2\ln(0.5)}\right] & = \log\left[0.5^{2x}\right] \\ \log\left[ -\frac{1}{2\ln(0.5)}\right] & = 2x \log(0.5) \\ \dfrac{\log\left[ -\frac{1}{2\ln(0.5)}\right]}{2\log(0.5)} & = x \\ x & \approx 0.2356 \end{aligned}$ so the x-coord of the point of tangency is $x \approx 0.2356$ .the y-coordinate of this point of tangency can be calculated using the original function: $\begin{aligned} f(x) & = (0.5)^{2x} \\ f(0.2356) & = (0.5)^{2 \cdot 0.2356} \\ & \approx 0.7213 \end{aligned}$ using point-slope form, the equation of the tangent line is $y - 0.7213 = -1(x-0.2356)$ the x-intercept of this tangent line is when the graph is at y=0. $\begin{aligned} 0 - 0.7213 & = -1(x-0.2356)\\ - 0.7213 & = -(x-0.2356) \\ 0.7213 & = x-0.2356\\ x & = 0.9569 \end{aligned}$ this rounds off to $x & = 0.957$ .choice c.

I’ll be a junior in high school next year and i’m aiming for top colleges like northwestern university, princeton, stanford, etc. i’m worried my schedule for next year isn’t challenging enough in the eyes of top colleges. my courses next year are: ap english lit, ap psychology, english 3 hn, pre-calculus hn, us history (only offered at an average level or ap which is a 2 semester course), physics (same reasoning as us history), students in action (a class centered around volunteer work), and creative writing (i want to major in creative writing or literature). is this a “challenging” junior year? i’m on the varsity swim team and i have a part-time job so i don’t want to overwork myself. i also have limited space in my schedule and can’t take both ap us history and ap physics (both are 2 semesters). i can always take ap biology (2 semester class) and get rid of both physics and us history altogether (i’d rather take ap bio than ap physics and i can easily take physics senior year) but i’d have to take us history online because it’s a required junior class. it all comes back around to i need us history no matter what.
