1. during a collision, the person not wearing a seatbelt is already in motion. there is no outside force (the seatbelt) to stop this motion. 
2. Kinetic Energy = 0.5 * m * v^2  because velocity is a squared term, doubling the velocity actually quadruples the kinetic energy, making the stopping distance much much greater
3. by the same logic as above, mass is not a squared term, therefore doubling the mass will double the kinetic energy, increasing the stopping distance -- but by not as much as increasing the velocity.
4. because a driver cannot alter the mass of his vehicle, the best way to enter sharp curves would be decreasing velocity (speed)
5. there are many factors that determine the degree of damage (to humans and property in a crash), most notably the size of the vehicle(s) and velocity.

Write the definition of a function typing_speed, that receives two parameters. The first is the number of words that a person ha
Lera25 [3.4K]

Answer:

The definition of function is as follows:

def typing_speed(number_of_words,Time_Interval):

number_of_words>=0  

Time_Interval>0

speed=float(60*number_of_words/Time_Interval)

return speed

Explanation:

Above function is defined step-by-step as follows:

        def typing_speed(number_of_words,Time_Interval):

  • A function named typing speed has two arguments, num_of_words and Time_Interval.

                             number_of_words>=0  

                             Time_Interval>0

  • The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.

                    speed=float(60*number_of_words/Time_Interval)

                    return speed

  • For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.

Which type of software is offered in trial form or for a limited period of time?
kkurt [141]

The type of software which is offered in trial form or for a limited period of time is called shareware.

Software which are offered for free in trial form or for a limited time period are called shareware. They operate on the principle that once the user understands what the software can offer they will pay to use it later.

Most shareware software has built in countdowns which start as soon as you start the trial and at the end of which access is automatically revoked. They require the user to form a simple account. These versions generally provide a very basic selection of functions and are used to rake in more paying users.

Types of shareware include:

  1. Adware: It stands for advertising-supported software where the advertisements generate revenues.
  2. Demoware: This is a trial version of the original software including all features.
  3. Crippleware: This software is free but provides limited features till it is purchased.
  4. Trialware

This provides the user with full feature access for a time limit and then requires purchase.
