Answer:Both Technician A and Technician B are right.
Explanation: The cracks in an engine can be detected when the engines are thoroughly cleaned because the transmission vent is basically designed to vent hot air.
Also pressure testing can equally detect cracks easily. When you increase the pressure,you will notice leaks from the blocks or cylinder indicating a crack on them.
 
        
             
        
        
        
Answer:  his total speed would be 3 seconds

Answer:

Explanation:
k = spring constant of the spring = 40 Nm⁻¹
A = amplitude of the simple harmonic motion = 4 cm = 0.04 m 
m = mass of the block attached to spring = 0.20 kg
w = angular frequency of the simple harmonic motion 
Angular frequency of the simple harmonic motion is given as 
 = Speed of the block as it pass the equilibrium point 
Speed of the block as it pass the equilibrium point is given as
