The speed of a wave in a uniform medium doesn't depend on its wavelength.
If object is not accelerating, the sum of all forces on the object will be equal to ZERO...
The answer is D.Competition with the Soviet Union spurred American space missions.

D=m÷v
so density would be 57.9 ÷ 3 = 19.3 g/cm³
Answer:
3331.5 kg
Explanation:
Given:
Spring constant of the spring (k) = 24200 N/m
Frequency of oscillation (f) = 0.429 Hz
Let the mass be 'm' kg.
Now, we know that, a spring-mass system undergoes Simple Harmonic Motion (SHM). The frequency of oscillation of SHM is given as:

Rewrite the above equation in terms of 'm'. This gives,

Now, plug in the given values and solve for 'm'. This gives,

Therefore, the mass of the truck is 3331.5 kg.
