One comparison is that both people in the cars (whether they were wearing a seat belt or not) is that they sustain injuries. People are obviously going to get hurt in a crash. A prime difference though is how big of an injury it is. People who were wearing seat belts at the time of a crash are less likely to have serious injuries, while those who weren't wearing seat belts have a higher possibility of sustaining really serious injuries.
Answer:
a) increase
Explanation:
The frequency of sound produced due to vibration of a string is governed by the following formula
n = 1/2L√T/m ;
L is length of the string in vibration, T is tension in the string and m is mass of string per unit length.
So frequency is inversely proportional to length of the string. Hence shortning of length of string increases the frequency of vibration.
I don’t use the metric system, so I used feet and then went back.
25 meters is about 82 feet.
So around 82 feet per minute (kinda slow LOL)
82 (feet per minute) x 90 (minutes) = 7380 feet (in 90 minutes)
7380 feet is equal to 2249.424 meters.
