seismic waves are not represented by electromagnetic graphs, nor can they be reflected on an electromagnetic spectrum. Visible light, radio waves, and microwaves are all electromagnetic waves, which are represented by graphs and electromagnetic spectrums.
Answer:
b) weaker
Explanation:
Hot rolled steel is generally weaker than the cold drawn steel. The yielding stress of cold rolled steel is higher than than hot rolled steel. At the same time the crystal structure remain the same in cold rolled steel. Giving it a better surface finish and closer tolerances. The strength and hardness of a cold roll steel is higher than the hot rolled steel
