I would say D. because you round to the nearest whole number and 0.04 is way less than 0.5 which is a good rounding up number.
Answer:
<em>Micro waves and radio waves are electromagnetic </em><em>waves while </em><em>ocean wave and seismic wave are mechanical waves. </em>
Explanation:
Electromagnetic waves do not require a medium for propagation. They can travel along vacuum just like they travel through matter.
Further examples of electromagnetic waves are x rays, infrared waves etc.
Spectrum of electromagnetic waves in the increasing order of frequency is radio waves, microwaves, infrared waves, visible light, ultraviolet, x ray, gamma ray.
Mechanical waves require a medium for propagation. Thus they cannot travel through a vacuum.
Sound wave is an example of mechanical wave.
Its becuase weight and mass are different. Even if an object weighs more than another object it might not have more mass than the other object.

Answer:
a) T=1.35s
b) amplitude = 0.0923m
Explanation:
m=300 gr
k=6.5 N/m
first we need to get the angular frequency of the motion
so we have that
ω = √(k/m)
in this case motion is a simple harmonic so the period is defined by:
T= 2π / ω
T= 2π / √(k/m)
replacing the variables...
T= 2π / √(6.5/0.3)
T=1.35s (period of the block's motion)
and...
α max = | ω²r max |
2 = (2π/1.35)² * r max
r max= 0.0923m
