Answer:
<em>The mass of the object is 40 Kg</em>
Explanation:
<u>Net Force</u>
According to the second Newton's law, the net force exerted by an external agent on an object is:
F = m.a
Where:
a = acceleration of the object.
m = mass of the object.
The mass can be calculated by solving for m:

The object has a net force of F=600 N acting on it and travels at
, thus the mas is:

m = 40 Kg
The mass of the object is 40 Kg
Answer:
ΔX = λ = 0.68 m
Explanation:
Wave speed is related to wavelength and frequency by the equation
v = λ f
where the speed of sound is 340 m / s
λ = v / f
λ = 340/500
λ = 0.68 m
this is the wavelength, it is the minimum distance for which the wave epitates its movement, which is equal to the distance between two consecutive compressions of the sound
ΔX = λ = 0.68 m
