The answer is "A mechanical wave transfers energy through matter."
I got it right on my quiz :)
The solution for this problem is:
99.5 MHz means 99.5 × 10^6 cycles/second.Electromagnetic radiation (counting radio waves) travel at 3.0×10^8 meters/secondWavelength = Speed/FrequencyThe wavelength of a 99.5 MHz radio signal is3.0 × 10899.5 × 106 meters=3.015 meters

Answer:
0.7 m/s
Explanation:
The following data were obtained from the question:
Distance travalled (d) = 190 m
Time (t) = 260 secs
Speed (S) =..?
Speed is simply defined as the distance travelled per unit time. Mathematically, it is expressed as:
Speed = Distance (d) /time(t)
S = d/t
With the above formula, we can calculate the speed of the security guard as follow:
Distance travalled (d) = 190 m
Time (t) = 260 secs
Speed (S) =..?
S = d/t
S = 190/260
S = 0.7 m/s
Therefore, the speed of the security guard is 0.7 m/s
