Answer:
No.
<em>Electromagnetic waves do not need a medium to travel through. </em>
Explanation:
Wave: A wave is a disturbance which travel through a medium and transfer energy from one point to another without causing any permanent displacement of the medium itself.
Waves are classified into two
(i) Mechanical Wave:These are waves that require a material medium for their propagation. E.g water wave, wave generated in a spring, and sound wave.
(ii) Electromagnetic wave: These are waves that do not require a material medium for their propagation. E.g light rays, radio wave, x-rays and gamma rays.
<em>Thus from the above explanation, electromagnetic waves do not need a medium to travel through. </em>
Answer:
C. Nuclear fission of uranium-235
When the two sides of a composition correspond to one another in size, shape and placement of form, the work has symmetrical balance. Symmetrical balance refers to the balance that is achieved when elements are arranged on either sides of a center of a composition in an equally weighted manner.
Answer
given,
mass of block = 0.21 Kg
speed = 1.70 m/s
spring constant = k = 4.50 N/m
using conservation of energy
a) K.E = P.E
x = 0.367 m
b) if the track is not friction less the maximum compression will be same as the compression in the part a.
Answer: I think it would be Different atoms
