As per Newton's law we know that
F = ma
here we know that
F = 4 N
m = 2 kg
so from this equation we will have
4 = 2 a
a = 4/2 = 2 m/s^2
so the acceleration will be 2 m/s^2
Note: I'm not sure what do you mean by "weight 0.05 kg/L". I assume it means the mass per unit of length, so it should be "0.05 kg/m".
Solution:
The fundamental frequency in a standing wave is given by
where L is the length of the string, T the tension and m its mass. If we plug the data of the problem into the equation, we find
The wavelength of the standing wave is instead twice the length of the string:
So the speed of the wave is
And the time the pulse takes to reach the shop is the distance covered divided by the speed:

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.
