When a person has experienced a tire blow out, there are steps to follow in order to prevent harm to others and self. After following the required and helpful steps after a tire blow out, slowed down and regain control, it is best that the person should head to a stop road or at the safe side of the lane where they won't be a bother to the road or to people driving in the high way. After pulling over to the side, it is advisable to turn on the emergency flashers of the car. This will set as a signal that you are in need of help or had gone through a problem.
        
             
        
        
        
<u>Answers</u>
(a)  6.75 Joules.
(b)  5.27 m/s
(c) 0.75 Joules
<u>Explanation</u>
Kinetic energy is the energy possessed by a body in motion.
(a) its kinetic energy at A?
K.E = 1/2 mv²
        = 1/2 ×  0.54 × 5²
        = 6.75 Joules.
(b) its speed at point B?
K.E = 1/2 mv²
7.5 = 1/2 × 0.54 × V²
V² = 7.5 ÷ 0.27
      = 27.77778 
V = √27.77778
    = 5.27 m/s
(c) the total work done on the particle as it moves from A to B?
 Work done = 7.5 - 6.75 
                  = 0.75 Joules
 
        
             
        
        
        
Answer:
wavelength = 0.968 m
frequency = 39.02 Hz
Explanation:
given data
mass = 0.0127 kg
force = 9.33 N
length = 1.93 m
to find out 
wavelength and Frequency 
solution
we know here linear density that is 
linear density =  .........1
   .........1
linear density =  
 
linear density = 6.5803 ×  kg/m
 kg/m
so 
wavelength will be here 
wavelength =  ..............2
   ..............2
here n = 4 for forth harmonic 
wavelength = 
wavelength = 0.968 m
and 
frequency will be for 4th normal mode of vibration is 
frequency =  ..........3
    ..........3
frequency = 
frequency = 1.036269 × 37.654594
frequency = 39.02 Hz
 
        
             
        
        
        
Answer:
High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms), ice storms, and duststorms. 
Explanation:High winds-  wind speeds as low as 23 knots (43 km/h) may lead to power outages when tree branches fall and disrupt power lines. Once wind exceed 135 knots (250 km/h) within strong tropical cyclones and tornadoes, homes  completely collapse,  and significant damage is done to larger buildings. Total disruption occurs once wind exceeds 175 knots (324 km/h)
Tornado- Typically look like a narrow funnel reaching from the clouds to the ground. Their wind speed goes from 65 to 250 miles per hour.
"An extreme weather condition in which we face the high speed wind in combination with heavy snow."
As for any blizzard has the normal wind speed of about 40 mph, and the visibility range reduces to less then 500 ft.
