Answer:
Velocity of truck will be 20.287 m /sec
Explanation:
We have given mass of the truck m = 4000 kg 
Radius of the turn r = 70 m 
Coefficient of friction 
Centripetal force is given  
And frictional force is equal to 
For body to be move these two forces must be equal 
So

Answer:
With more particles there will be more collisions and so a greater pressure. The number of particles is proportional to pressure, if the volume of the container and the temperature remain constant. ... This happens when the temperature is increased.

Answer: 
M = ρ V = 9 gm/cm^ 3 * cm^3 = 27 gm
a = (V2 - V1) / t = (6 - 2) m/s / 12 s = 1/3 m/s^2     the acceleration
F = M a = 27 gm * 1/3 m/s^2 = 9 dynes      net force applied
 
        
             
        
        
        
Speed = (frequency) x (wavelength)
Speed = (19 per second) x (7 mm)
Speed = (19 x 7) (per second · mm)
<em>Speed = 133 mm/sec</em>
or you might want to write  <em>Speed = 0.133 m/s</em> .
