 Page 2 / 11

Uniform velocity

Velocity is uniform when equal distances along a straight line are traversed in equal intervals of time. In this case

v = s/t

where

• v is uniform velocity
• s is the distance traveled (displacement)
• t is an interval of time

Because uniform velocity occurs along a straight line, the computations involving uniform velocity, distance, and time may notnecessarily include the direction of that straight line. However, since both displacement and velocityare vector quantities, it is understood that the direction of velocity is the same as the direction of the displacement.

On the other hand, as you will see later, when combining two or more uniform velocities into a single resultant velocity, the directions of thedifferent uniform velocities becomes extremely important.

Speed, distance, and time

Note also that this same equation can be applied to computations involving speed, distance, and time where

• v represents speed and not velocity
• s is the distance traveled (not necessarily in a straight line)
• t is an interval of time

Units of velocity

The units of velocity are units of distance (such as meters) divided by units of time (such as seconds).

## A simple exercise on uniform velocity

Let's begin this section with a short exercise involving uniform velocity.

How long does it take an airplane traveling at a uniform velocity of 350 miles per hour to traverse a distance of 700 miles?

Please copy the code shown in Listing 1 into an html file and open the file in your browser.

Listing 1 . A simple exercise on uniform velocity.
```<!---------------- File JavaScript01.html ---------------------><html><body><script language="JavaScript1.3">document.write("Start Script" + "<br/>") var velocity = 350;//uniform velocity in miles/hourvar distance = 700;//miles var time = distance/velocity;//miles/(miles/hour) = hoursdocument.write("uniform velocity = " + velocity + " miles/hour<br/>"); document.write("distance = " + distance + " miles<br/>"); document.write("time = " + time + " hours<br/>"); document.write("End Script")</script></body></html>```

```Start Script speed = 350 miles/hourdistance = 700 miles time = 2 hoursEnd Script```

Analysis of the code

The equation given earlier that shows the relationship among uniform velocity, distance, and time can be manipulated algebraically tofind any one of the three terms when the values of the other two terms are known. The objective in this exercise is to find the time required to traverse a known distance witha known uniform velocity.

Algebraic manipulation of the equation

Multiplying both sides of the equation by t and dividing both sides by v allows us to rewrite the equation as

t = s/ v

where

• v is uniform velocity
• s is the distance traveled
• t is an interval of time

The solution to the problem is...

This version of the equation is used in Listing 1 to solve for the time required to traverse 700 miles at a uniform velocity of 350 miles/hour. Theanswer is 2 hours as shown in Figure 1 .

The given of f(x=x-2. then what is the value of this f(3) 5f(x+1)
hmm well what is the answer

how do they get the third part x = (32)5/4
can someone help me with some logarithmic and exponential equations.
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
hmm
Abhi
is it a question of log
Abhi
🤔.

what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.

algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

can nanotechnology change the direction of the face of the world
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
