The difference is that electromagnetic waves can travel through the vacuum of space but however mechanical waves only travel through air and solid materials
The answer is C, i just did it and got it right so you can trust this answer, i wrote so much because of the 20 character thing

It is c.a decrease of gravity!!
The given question is incomplete. The complete question is as follows;
The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a relative rate of 16% per hour. Suppose that a sample culture has an initial population of 71 bacteria. Find the predicted population after three hours Do not round any intermediate computations, and round your answer to the nearest tenth bacteria
.
Answer:
114.7
Explanation:
A (t) represent the population of the bacteria at the time t.
Since, the population grows exponentially, the population can be calculated as follows:
A (t) = Ao ×
A (t) is teh final population, Ao is the initial population, e is the exponential, k is rate and t is time.
A (t) = 71 ×
For t = 3 hours
A (t) = 71 ×
A (t) = 114.7.
The population of bacteria after 3 hours is 114.7.
